Notebookcheck's Best of December 2012

The reviewers were not inactive around Christmas. We reviewed 31 notebooks and numerous tablets and smartphones, which we elect separately: Best of December 2012 – Smartphones and Tablets. Looking back, which devices did we like most in December? We compare laptops of five categories and elect a winner in each. Dell 1720 charger

Alike in November Windows convertibles are gaining ground. But, only Lenovo's IdeaPad Yoga 11 uses Windows RT. This is not surprising as it comes with a Tegra 3 SoC. Samsung's ATIV Smart PC and Acer's W510 are tablets which can turn into a clamshell notebook via Keyboard-Dock. Compaq CQ70 charger

We again had a lot of subnotebooks under review in December. Lenovo's ThinkPad T430u is a special contender, because it comes with a GeForce GT 620M despite a low price (T series). With the Fujitsu Lifebook P702, the old laptop style returns for a moment: conventional input devices, a lot of interfaces, and a matte display. Unfortunately the wobbly case cannot keep up with today's stiff plastics chassis. G6000 charger

As Office notebooks are demanded just before Christmas, we reviewed as much as nine. HP' ProBook 6570b, 6470b, and 4540s show professional ambitions, while the IdeaPad S405 and U510 turn out inferior. Especially the S405 can not meet the needs of its target group.

General-purpose laptops with big diagonals and decent to very good gaming performance have always been popular. We do not talk about gaming notebooks, as the graphics cards are mid-range. In December none of the devices proved to be especially good. Acer, HP, and Samsung achieved a rating of 83 % each. Many of our test samples are about on par, but not all of them, as the beaten devices from Asus and MSI prove. Lenovo R61 charger

Finally, two dissimilar gaming bolides competed, Asus' G75VX and MSI's GX60. Because of the AMD quad core, the most powerful Radeon, the HD 7970M performs vastly inferior. What did the "gaming specialists" think when they chose this configuration?

The only workstation of this month did not have any competitors: The Bullman E-Klasse 4 i7 17FHD (84 %) is a mobile 17-inch CAD workstation equipped with powerful Nvidia Quadro K3000M graphics card and Core i7 3940XM, the fastest mobile processor in Q3 2012. HP dv6 charger

After the 13-inch Yoga 13 (November) we reviewed the 11.6-incher. In being equipped with Tegra 3 and a 64 GB SSD it could be a typical tablet, but why does it cost nearly 800 Euro? Because it comes with Windows RT and features a clever folding mechanism. Its hinges allow the display to be turned by 360 degrees and afterwards the keyboard (deactivated in this mode) is the underside. We like its build quality, materials, and runtime. But, the keyboard with poor feedback somewhat dampens our enthusiasm. And the connectivity is minimalistic for a Convertible. On the other side, a tablet with three fully-fledged USB-ports is a nice thing, but, as a tablet, the Yoga 11 is inherently bulkier and heavier then its super-slim Android competition. The later often feature higher resolutions. 1366 x 768 pixel do no longer appear to be opportune for a premium device. But, we cannot complain about colors and brightness. By the way, Lenovo just introduced the Intel model called Yoga 11s at the CES 2013 in Las Vegas. HP 8530w charger

Samsung's ATIV Smart PC XE500T1C combines an Intel Atom Z2760 (designed for tablets) with a fully-fledged Windows 8. Performance freaks won't appreciate this, while standard users will dislike the small 64 GB SSD, because only 32 GB are free on delivery. The keyboard dock does not belong to the best of its kind, but the mouse replacement and the keys are better than the Yoga's. The operating concept is appropriate, but docking and undocking could get annoying after a while. Lenovo R500 charger

Acer's Iconia Tablet W510 uses the same technology as the ATIV Smart PC, but is a little bit smaller (10-inch). HD resolution, IPS panel, Atom processor and 64 GB SSD are in a well built case. Unfortunately, the keyboard (tightly packed layout) and the touchpad (hangs, no multi-touch) perform poorly. The 13:35 h battery life could not be better and the brightness of nearly 300 cd/m² is also available on battery. The price of about 600 Euro is lower than the ATIV Smart PC's, which features a built-in 4G-modem. Notebook 6730b charger

Lenovo's ThinkPad Twist ultrabook is a conventional convertible. Size and weight are typical for a 12.5-inch ultrabook. The Twist does not try to be a light and slim Windows tablet. First of all it is a subnotebook with decent performance with optionally a classic tablet mode. The advantage of the Twist is its decent performance for Windows 8, the many interfaces typical for notebooks and the good keyboard (but, a poor touchpad). It is rather designed for business use, but the short battery life of 3:16 hours (WiFi test) is disappointing. HP 8530p charger

Convertible notebook of December 2012: Lenovo IdeaPad Yoga 11

While the operating concept of the SmartPC, which achieved the same rating as the Yoga 11, is appropriate, we did not like its weak netbook hardware. If being handy and mobile is a criterion, we would chose Windows RT and the Yoga 11. The folding wonder will find its fans as its possible fields of application in job, study, or private life are enormous. Furthermore, using docking keys is only limited joy (Smart PC, Iconia W510). In our opinion, single unit devices are smarter solutions. IBM G40 charger

The 14-inch Lifebook S752 from Fujitsu looks a little bit bulky. However, neither beauty nor ultimate performance are important in this category. Instead, the Lifebook scores points with excellent ergonomics (waste heat, system noise), decent build quality, long battery life (6:27 Stunden) and a keyboard with strong feedback. Its plastics look and Core i3 are unremarkable. The hard drive is slow and only 2 GB RAM are unbalanced. This is too miserly for 700 Euro. Lenovo Z560 charger

HP's ProBook 6570b achieved the same rating. Input devices and build quality are slightly better, but the matte display is striking in the office category: contrast of 1000:1 and brightness of 271 cd/m². As it is a TN panel the 1600 x 900 pixels screen has narrow viewing angles. The ergonomics is not that perfect as the Lifebook's, but it can score points in connectivity with a docking port and even a rare RS-232 (serial). Its biggest weakness is the short battery life of only 2:23 hours. SAMSUNG RV420 charger

We continue with the ProBook 4540s, which is also a 15.6-incher. The 4xxx models are designed for ProBook novices, which have to live with lower resolution (HD), contrast (370:1) and without docking port. Our test sample with Core i3 and 7200 rpm hard drive costs 525 Euro and delivers a decent office performance. Furthermore, HP did not save in the important aspects, keyboard, touchpad, stability of the case and heat management, which are of best ProBook quality. LENOVO Y580 charger

ProBooks keep coming. Finally, the 14-inch sister model of the 6570b mentioned above faced up to our critical review. The 6470b does not feature a dedicated graphics card and the display only has HD (1366 x 76 resolution. Unfortunately, the user can not appreciate the vibrant colors and the decent brightness of the 6570b. Strange enough: Now the battery life of 4:23 hours is balanced. Important aspects like input devices, build quality, temperature, and connectivity are largely on par with its 15.6 inch sister. HP 576833-001

In regards of display the Asus P45VJ (14-inch) does not perform well (brightness: 196 c/m²). But, it costs significantly less then the 14-inch Probook despite coming with a relatively powerful GeForce GT 635M. High-end business features like docking port, ExpressCard or eSATA/serial are missing. The stable plastics chassis appears rather consumer-oriented. The same is true for the input devices, which do not feature the ProBook's strong feedback. The battery life (4:43 hours) is alright. To summarize, the Asus P45VJ is a compromise for consumers who like to play computer games and are looking for a laptop for work and entertainment. ASUS X71SL charger

If you do not want to spend 800 Euro for a mobile computer, you'll maybe come across Acer's TravelMate P243-M for 550 Euro. The 14-inch laptop features a stable carbon/Mg-AI case, a decent keyboard (touchpad is not that good) and a battery life above four hours. The low brightness of the TFT on battery (130 cd/m²) is disappointing. The TravelMate is only an alternative if interfaces typical for the consumer range (no docking port) are sufficient. Fujitsu FMVNBP199

Lenovo's IdeaPad S405 also wants to be cheap. It features an AMD Radeon HD 7600G and an AMD A-Series A8-4555M for 550 Euro. The performance of the 14-inchers is very low and so is its energy consumption. This could have resulted in excellent battery runtimes, but due to its small 32 Wh battery only just three hours are possible. The plastic chassis twists, the keys spring, and the brightness of the display is low. Not even the price is a buying criterion as comparable and partly better Core i3 alternatives cost the same. Samsung NP-Q45 charger

The IdeaPad U510 from the same manufacturer is a 15.6-incher cheekily categorized as ultrabook. It's up to the user's discretion whether weight (2.2 kg) and height (24 mm with feet) still conform to this claim. In mobility it achieves 5 hours with Core i5 and HD 4000. Because of the relatively dark, reflective display, the U510 is rather an elegant indoor device. The aluminum look reminds on the MacBook Pro series, but the flexibility of the base unit unmasks the imitator. SONY VGP-BPS20/B

The Maxdata M-Book 4000 U G1 Select is a cheap ultrabook. The build quality is not disappointing and the matte, high-quality surfaces hardly show any weaknesses, but do also not achieve a top rank as an alu unibody would. We appreciate the long battery life of above six hours, but the matte, dark HD display cannot be used in the sun. For an interesting price Maxdata incorporates a genuine 128 GB SDD (no hybrid), which is unfortunately very slow. Unfortunately, it can not keep up with high-end devices in ergonomics and display. Under load the M-Book 4000 U gets louder and warmer than other 14-inch ultrabooks. Toshiba PABAS098

Office notebook of December 2012: HP ProBook 6570b

Despite its short battery life we elect the ProBook 6570b and not the Lifebook S752, because we want to honor the decent HD+ panel after countless pale office displays. Too often this important user interface is just an ordinary TFT.

Acer's Aspire TimelineUltra M5-581TG can be described as gaming-capable ultrabook with sufficient display size. The GeForce GT 640M (Kepler, newest chip generation) and Core i5 provide gaming power on-the-go. This is the first ultrabook that achieves a gaming rating of 86 %. It even outperforms the HP Envy m6-1101sg (Radeon HD 7670M) with standard voltage Core i5. Despite a its relatively low price of 800 Euro it achieves a high level in build quality (89 %) and battery life (5 hours WiFi test). Toshiba PA3534U-1BRS

It's much more difficult for the HP Envy m6-1101sg with similar price to attract gamers. The 15-incher comes with HD 7670M and Core i5 3210M does not score that well in keyboard and build quality, but performs better in ergonomics, while the battery runtime is about on par. Both competitors have a reflective TN display with narrow viewing angles. The Envy m6-1101sg somewhat excels with a contrast of 571:1. Toshiba W100 charger

Fast gaming and good looking? That's what Samsung thought when they updated their series 7 (model 700Z5C) with a powerful GeForce GT 640M. Together with a Core i7 it is slightly faster than the Aspire M5-581TG low voltage system. A lot of games can be stored on the 1,000 GB hard drive, but poor contrast (144:1) and narrow viewing angles are outperformed by the HP Envy m6. This is a pity as the matte display feature a comfortable 1,600 x 900 pixel resolution. Customers expect a better color representation for 1,400 Euro. The series 9 models demonstrate how this can be accomplished with a matte IPS panel. ASUS G75V Charger

Do you demand an excellent display? If only the 700Z5C could change displays with the Envy dv7-7202eg. The 17-incher features a matte FullHD display, which is not only bright, but also achieves a contrast of 868:1. The TN panel performs above average in viewing angels and sRGB is nearly covered. In contrast, high system noise and relatively few interfaces devalue the dv7. Gamer will spurn the GeForce GT 630M, which is significantly slower than the 640M. Games do sometimes not even run smoothly in HD resolution. Here the GT 640M would have been much appreciated. LENOVO L08S6D13

If you do not want to spend 1,200 Euro for the Envy dv7, you might be interested in the HP Pavilion g6-2200sg. The 15.6-incher comes with a contrast-rich HD display and a gaming capable AMD Radeon HD 7670M for significantly less than 500 Euro. The good news from our test: Its Pentium processor does hardly limit gaming performance. Most of today's games run smoothly in native resolution. But, users have to live with a complicated GPU switch and a moderate build quality. Dell T1G6P

Same CPU, but less fun due to an AMD processor? This is our verdict on the 460 Euro cheap Asus K53TK. The AMD A-Series A4-3305M slows down the Radeon HD 7670M in games. Games even run faster on HP's Pavilion g6-2200sg with cheap Pentium. The display features decent contrast (595:1) and the battery keeps up with the Pavilion g6-2200s'. HP 6830s charger

The K series from Asus is also available in 17-inch. We reviewed the powerful model with GeForce GT 635M and Intel quad core (nearly 800 Euro). The gaming performance is slower than with GT 640M, but suffices high details in HD resolution. But, the native 1600 x 900 pixels screen is not much fun. Pale colors, low brightness and narrow viewing angles indicate that it is an ordinary display. The second 2.5 inch hard drive slot is a special feature. Lenovo E530 charger

If you want to save money, do it right. The MSI CX61 is available for barely 600 Euro in virtual shops. The 15.6-incher houses a GeForce GT 635M and a Core i5 3210M. Its gaming performance is solid and similar to the Asus K75VJ-TY102H's. Not everyone will like the moderate build quality (input devices too) and the unstable chassis is not well manufactured. In addition, the short battery life, the poor display and the loud system noise under load downgrade the laptop. Asus A42-U46

Multimedia notebook of December 2012: Acer Aspire M5-581TG

One laptop must win. The same rating forces us to balance pros and cons. We elect Acer's Aspire M5-581TG as it combines decent build quality and high performance. Users will gladly live with high waste heat and loud system noise under load as this is the ultrabook currently running games fastest. None of the notebooks with a rating of 83 % features a really decent display. If you appreciate such a thing, consider the HP Envy dv7-7202eg.

The G75VX is the gaming bolide from Asus. The flagship now comes with NVIDIA GeForce GTX 670MX. So, it is based on the newest Nvidia-Kepler architecture. Together with the i7 3630QM the 17.3-incher can run all games without problems - but not all of them in native full HD resolution. Despite lacking Optimus, the battery life of three hours is remarkable. However, the 4.2 kg bolide needs a 74 Wh battery to accomplish this. We still have to criticize the suboptimal interface layout, but we like the high-quality case and the bright matte display with appropriate contrast (454:1). However, we expected an IPS panel for 1,600 Euro. Dell E6500 charger

Rashly, MSI combined the most powerful AMD GPU with the weak AMD A-Series A10-4600M. This is the only way to keep the low price of 1,200 Euro. In terms of performance this mobile quad core is on par with a Core i3. Accordingly, the results of the gaming tests are sober. The A10 often slows down the Radeon HD 7970M that much, that games can only run on mid-range level. That said, the gentle reader can also buy a GT-640M system like the Acer Aspire M5-581TG above with better build quality (incl. input devices), weight on ultrabook level and low brightness for less than 900 Euro. The matte full HD display of the GX60 with good brightness, decent contrast and appropriate viewing angles is useful during games and work. The two mSATA-SSDs in RAID 0 are less impressive than expected. In reading small blocks the Raid-0 configuration performs poorly and worse than Solo SSDs (4K test: 8 MB/s). Fujitsu FPCBP88

Gaming notebook of December 2012: Asus G75VX-T4020H

According to the rating, the decision is easy. The G75VX profits from the MSI's fatal combination of strongest Radeon GPU with AMD quad core. The 17-incher from Asus keept its strength (ergonomics, input devices) and improved performance with the newest Kepler GPU. All things considered, there are no serious points of critique as even the matte FHD display can convince us completely.

HP Envy dv7-7202eg Notebook

The HP Envy dv7-7202eg we have put through its paces represents the flagship model from the dv7-7200 series which comprises eight notebooks in total. The currently 1200 Euros expensive 17.3 inch juggernaut with a Full HD resolution (1920 x 1080 pixels) houses an Intel Core i7-3630QM quad-core processor and a total of 12 Gigabytes of DDR3 RAM. Concerning graphics processing the choices are either the Intel HD Graphics 4000 graphics chip integrated into the processor, or the Nvidia GeForce GT 630M GPU. The HP Envy dv7-7202eg stores its data onto two 750 Gigabyte capacity hard drives and also has a Blu-ray burner. Replacement battery for HP ProBook 4340s

In order to determine the relative performance of the notebook in the bigger picture, we compared the Envy dv7-7202eg with some of its other HP colleagues, including the Envy dv6-7202eg, the Pavilion g7-2007sg and the Pavilion dv7-7000sg; as well as with three other models: Lenovo IdeaPad G780, Toshiba Satellite P875-30E and the Wortmann Terra Mobile 1773Q. Replacement battery for HP ProBook 4341s

The midnight black case of the Envy dv7-7202eg makes a good impression visually: The back of the display and the base unit are both covered with a matte aluminium layer which is surrounded by silver colored plastic around the edges. One other exception to the almost entirely black notebook is the HP logo on the lid which illuminates white when the notebook is switched on. Together with the rounded edges of the case and the perforated speaker panel above the keyboard, this provides for an altogether classy appearance. The metal look hasn't been rigorously adhered to by HP however, since the display frame has a shiny surface which doesn't evoke a particularly qualitative impression. Replacement battery for HP ProBook 4440s

We couldn't find any reason for criticism when it came the the thoroughly successful manufacturing quality. The case of the Envy dv7-7202eg is very stable and can only be warped marginally thanks to the solid aluminium elements of the case. All the components are precisely made and fit together exactly, while only denting marginally when pressure is applied. Due to the rigidity of the hinges it is necessary to use two hands to open the notebook, but the display is held firmly in place. Replacement battery for HP ProBook 4441s

Performance

The HP Envy dv7 series is altogether composed out of eight high performance multimedia notebooks, whose performance should be more than enough for daily use including internet browsing, video playback and word processing. Thanks to its good display and its other hardware components the Envy dv7-7202eg also still has ample performance reserves for significantly more demanding applications, which allows it to also be used for graphics intensive games and video editing.

Replacement battery for HP ProBook 4446s

System Performance
As can be expected from a notebook in the desktop replacement segment, the HP Envy dv7-7202eg provides a swift pace in Windows 8. With the PCMark 7 benchmark our reviewed notebook reached a score of 2645 points, and is thus level with the Lenovo IdeaPad Y580 (2646 points) and the Acer Aspire S3-391-53314G52add (2656 points). Juxtaposed to its predecessor our reviewed candidate isn't able to set itself apart considerably though - something that isn't surprising since both devices have the same CPU and GPU configuration. Replacement battery for HP ProBook 4540s

The Envy dv7-7202eg certainly isn't lacking storage capacity: The notebook has a total of two 2.5 inch Hitachi Travelstar 5K750 HTS547575A9E384 hard drives with 750 Gigabytes each of capacity. One of these contains the operating system and the recovery partition, while the second drive is completely empty. The Hitachi Travelstar 5K750 has an 8 Megabyte cache and operates with a rotational speed of 5400 revolutions per minute. It connects using the SATA-II interface with a nominal bandwidth of 3 Gb/s, and should be more than enough for most applications. Compared to notebook hard drives that operate at 7200 revolutions per minute, the Hitachi drive may be slower but is by no means out of place in the dv7-7202eg: The CrystalDiskMark benchmark ascribes the HTS547575A9E384 a read speed of 93.53 MB/s and HD Tune reports an average transfer rate of 75.2 MB/s. Considering the 1200 Euro price tag an SSD instead of one of the hard drives could also be a welcome change though. Replacement battery for HP ProBook 4545s

For the sake of protecting the two 2.5 inch hard drives HP has pre-installed the software 3D DriveGuard, which monitors the accelerometers of both drives and thus recognizes sudden shocks, in which case the tool parks the read and write heads of the Hitachi HDDs in order to avoid them getting damaged. Replacement battery for HP ProBook 4740s

Gaming Performance
Thanks to its Nvidia GeForce GT 630M GPU the HP Envy dv7-7202eg can also be used to play up to date games. These were almost all smoothly playable without any judders during our test with medium quality settings and a resolution of 1366 x 768 pixels. Especially demanding games such as Battlefield 3 do however force the dv7-7202eg to its limits, since the game already starts to judder with medium details settings and resolutions. Replacement battery for HP ProBook 6475b

Temperature
Day to day tasks don't even make the dv7-7202eg break a sweat, since the case surfaces on the top and bottom sides hardly get warmer than 25 degrees Celsius. Thanks to this it is also possible to use the notebook on your lap without any problems. When fully utilized with Prime95 and FurMark during our stress test the reviewed notebook did start to get into its stride though, and we measured a maximum temperature of 45 degrees Celsius on the top surface, and up to 48 degrees Celsius on the bottom. The HP Envy dv7-7202eg does however remain substantially cooler than its dv6-7202eg predecessor, whose case reached temperatures of 61.7 degrees Celsius. Replacement battery for HP ProBook 6470b

Battery Life

Power Consumption
Despite its good performance the HP notebook still proves to be relatively frugal in an idle state, with an idle power consumption between 10.4 and 17.9 watts, which more or less the same as similarly equipped rivals. When fully utilized the power consumption increases considerably, and reaches up to 84.2 watts during the 3DMark 2006 benchmark. Theoretically the notebook would be able to cope with a higher power consumption, since HP have provided the dv7-7202eg with a 120 watt AC adapter. The Lenovo IdeaPad G780 is much more economical in this respect with a maximum power consumption of 62.9 watts when fully utilized. Replacement battery for HP ProBook 6570b

Battery Runtime
During ideal conditions (idle state, all power saving options enabled, WLAN and Bluetooth off, minimum display brightness) the HP Envy dv7-7202eg manages to stay on its feet for 3:26 hours. Considering the measured power consumption the notebook therewith falls far short of our expectations. Thus our reviewed candidate is not only less enduring than its Envy dv6-7202eg predecessor (7:44 hours), but falls behind into last place compared to the other rivals. The closest contender is the HP g7-2007sg with 5:38 hours, while the Wortmann Terra Mobile 1773Q lasts the longest with 10:06 hours. Even a repeated iteration of the test with checking of the settings didn't yield any better runtimes. Replacement battery for HP EliteBook 2170p

When fully utilized the battery runtimes do however start to converge: In this case the HP Envy dv7-7202eg manages 1:41 hours (HP g7-2007sg 0:46 h, HP Envy dv6-7202eg 1:25 h, Wortmann Terra Mobile 1773Q 2:30 h). Replacement battery for HP Folio 13

During our practical WLAN test the notebook held out for 3:13 hours (Lenovo G780 2:22 h, HP Envy dv6-7202eg 4:17 h, Wortmann Terra Mobile 1773Q 7:48 h). During this test a website is refreshed every 40 seconds while the power saving profile is activated and the display brightness is reduced to 150 cd/m². Last but not least came the playback test which we carried out with a Blu-ray disc to represent optical media. Too long movies probably shouldn't be on the agenda though, since the battery is empty after 2:01 hours (HP Envy dv6-7202eg 3:20 h, Toshiba Satellite P875-30E 3:34 h, Wortmann Terra Mobile 1773Q 4:26 h). Replacement battery for HP Folio 13-1000

A very good display, more than enough performance for applications of all kinds, and a correspondingly appealing appearance and haptics - for the official retail price of 1200 Euros the HP Envy dv7-7202eg provides a lot of value. Positive aspects of the reviewed notebook furthermore include a Blu-ray burner, three fast USB 3.0 ports, the integrated fingerprint reader for additional security, and the two 2.5 inch hard drives with 750 Gigabytes of storage capacity each. The other models from the Envy dv7 series may be more affordable, but also have less potent CPU/GPU combinations. Replacement battery for HP Folio 13-2000

The HP Envy dv7-7202eg starts to fall short when it comes to the gaming performance though, which starts to reach its limits with particularly hardware intensive games due to the Nvidia GeForce GT 630M graphics card. We were also a bit disappointed with the comparatively short battery life, and the relatively loud system noise when fully utilized. In cases when a notebook with a long battery life is important the Wortmann Terra Mobile 1773Q, which also has a somewhat more powerful GPU (Nvidia GeForce GT 640M), would be a better choice.
