Review One K56-3F (Clevo W650SR) Notebook

Florian Glaser (translated by Bernie Pechlaner), 07/05/2013

Low-key multi-talent. The One K56-3F is a 15-inch all-purpose notebook equipped with a Haswell processor, Nvidia's attractive GeForce GT 750M GPU, and a razor-sharp Full HD display. How does the One K56-3F stack up against competitors like the Asus N56VB, the Samsung Chronos 770Z5E, and the Toshiba Satellite P70?

For the original German review, see here.

Users in search of a highly configurable notebook should take a look at One. Just like the gaming-systems K56-3N2 and K73-3N, the K56-3F offers many different equipment and configuration options.

First off: the processor choices. The Core i7-4700MQ (2.4-3.4 GHz), Core i7-4800MQ (2.7-3.7 GHz), and Core i7-4900MQ (2.8-3.8 GHz) are quad-core CPUs from Intel's brand-new Haswell generation. Considering the performance of the GeForce GT 750M - which is the limiting factor for most 3D applications in this case - even a less expensive dual-core CPU should be sufficient.

As far as "sufficient" is concerned: 4-8 GB of RAM should satisfy most home users, even though the notebook offers two DDR3 RAM slots for a maximum of 16 GB RAM. The most difficult decision is going to be the hard drive configuration: the K56-3F can be equipped with mSATA drives from 60-256 GB but also offers a regular-sized opening for 2.5-inch HDDs, SSDs, and hybrid drives.

The WLAN module is either sourced from Intel (Centrino Wireless-N 2230 or Centrino Advanced-N 6235) or from Qualcomm Atheros (Killer Wireless-N 1202). There are also three choices for the optical drive - the notebook can either be equipped with a DVD-RW, a Blu-ray drive, or a Blu-ray writer. The system does not come with an OS, although it can be equipped with one for a surcharge (Windows 8, 64-bit).

The base version of the notebook retails for 799 Euros (~$1048)our test system - as configured - would sell for 1144 Euros (~$1500).

Case

Like most other One notebooks, the K56-3F is based on a chassis from Clevo. The W650SR barebone (which is almost identical to the W650EH) measures 374 x 252 x 35 millimeters and is thus not overly massive.

The slightly slower Asus N56VB (GeForce GT 740M) mentioned earlier is almost exactly the same size. Compared to the W350ST barebone, which is equipped with the significantly more powerful GeForce GT 765M, the W650SR appears a tad slimmer. We really like the look of the 15-inch system with its clear lines and matte finish. Since none of the surfaces are glossy, the notebook doesn't attract dirt nearly as much as a lot of its competitors.

The display lid is noteworthy as it features a brushed aluminum finish which looks surprisingly real even though it's just an imitation. The 15-inch system looks quite upscale - but there's no denying the fact that the surfaces are made from inexpensive plastic.  The build quality also doesn't come close to that of the Samsung 770Z5E (Radeon HD 8870M). In addition, the chassis is not particularly sturdy: both the area above the drives and the display lid are not very rigid.

Typical for Clevo, the hinges are a bit wobbly and the lid bounces back and forth when the base unit is subjected to vibrations. Fortunately, the system is spared from another typical Clevo misstep: the display bezel is not high-gloss as we have seen in the past. The weight also seems appropriate: 2.6 kilograms is not too cumbersome to lug around. The clear and unobtrusive design also fits in well in various environments.

Connectivity

Ports

The port selection is on par with what other multimedia notebooks have to offer. The back of the unit only contains the battery, the front edge houses the 9-in-1 card reader. The right side is home to a Kensington lock slot, a USB 3.0 port, a USB 2.0 port, and two audio jacks (headphone and microphone).

The front area of the left side contains the VGA and HDMI ports, an RJ-45 jack, an eSATA/USB 3.0 combo port, and an additional USB 3.0 port. The power jack is located behind the fan exhaust. 

Using a mouse on the left side of the notebook can - depending on how many ports are occupied - not only result in a warm hand because of the exhaust fan, but also makes for a rather crowded workspace. Other Clevo barebones, like the aforementioned W350ST, feature - in our opinion - a much better port distribution.

Wireless Communication

Wireless communication is courtesy of the Centrino Wireless-N 2230 module, which supports WLAN 802.11 b/g/n and Bluetooth 4.0 as well as Wireless Display and Smart Connect. The maximum transmission rate of the module - which is known for its reception quality (although it doesn't support the 5.0 GHz band) - is 300 Mbit/s according to the manufacturer.

Maintenance

Upgradeability and maintenance are strong points of the Clevo barebones. The W650SR is a great example: the maintenance cover can be removed with a simple Phillips screwdriver and reveals all major components underneath. Compared to other manufacturers like Acer (see for example the Aspire V3-772G), the user can easily access the cooling system. Even the heat-pipes of the GPU (which cannot be replaced) and the CPU (replaceable) can be unscrewed. An upgrade of the hard drive or the RAM also poses no problems.

Software

We appreciate the clean Windows install free of bloatware. As shipped, the system only comes with 14 programs - although we find it curious that One omitted the Sound Blaster Cinema software which improves the sound quality (it's possible that the software was simply forgotten).

One can't be held accountable for the outdated GPU driver (ForceWare 311.27) - Clevo has some additional work to do here. Official drivers from Nvidia are not available yet.

Accessories

Only the most basic accessories are included - aside from a DVD with drivers and a quick-start guide, the box is empty. However, the power adapter has been improved. While the multimedia barebone W150ER came with a big and clunky power adapter, the W650SR includes a 120 watt unit which is only 2.5 inches high and weighs a modest 470 grams. The 6-cell battery weighs in at 330 grams.

Warranty

The notebook is covered for a standard 12 months. Longer warranty coverage (to 24 and 36 months) or an extension of the pickup and return service cost extra - although the price is fair.

Input Devices

Keyboard

We find it a bit disappointing that Clevo didn't utilize the backlit keyboard found on the 15-inch P150SM and P157SM, but rather decided to incorporate the old chiclet-style version, which lacks this useful feature.

Another limitation is the dedicated number pad: while the one found on the W350ST barebone is four keys wide, the K56-3F has to make do with three. Otherwise, the layout of the keyboard is clear and concise. The keys feature rounded corners, measure a decent 14 x 14 millimeters, and the lettering is easy to identify. The feedback and resistance should satisfy most users, although the keyboard might be too clattery and noisy for some.

A point of criticism: the space bar, which doesn't register inputs well if not hit dead center. We have had the same problem with Clevo's chiclet keyboard on several occasions before. Especially when playing multiplayer titles, the unreliable input gets annoying.

Touchpad

The touchpad (Elan Smart Pad) was a pleasant surprise. A usable surface area of 107 x 62 millimeters is pretty uncommon for 15-inch systems. The pad is recessed slightly and features a smooth surface, which feels nice to the touch but doesn't allow fingers to glide that easily.

Gestures are also supported. Zooming, turning images, and scrolling all work fine; the precision is adequate and we never had any problems with inputs not being recognized.

The bottom of the touchpad houses two conventional mouse buttons, which feature a decent click mechanism. Since the touchpad is not right underneath the space bar, gaming doesn't necessarily require deactivation of the touchpad.

Display

According to One, the company initially was only able to acquire the W650SR barebone with the glossy Full HD display. Too bad - the glare panel (N156HGE-LB1) not only suffers from strong reflections, but also has several additional weaknesses.

The black value is relatively high at 0.6 cd/m² - compared to better panels, dark scenes in movies are more gray than black. For truly deep blacks, this value has to be less than 0.3 cd/m². Color accuracy and color space coverage are also less than stellar (see the screenshots below).

As far as the brightness is concerned, the display does well: 330 cd/m² is higher than what most competing systems are capable of (standard panels reach between 200 and 300 cd/m²). The contrast ratio of 600:1 is also quite decent.

The resolution of 1920x1080 pixels might seem high to some - especially since more system resources are required - but the desktop workspace is consequently quite generous, which makes multitasking with several windows open that much easier. Taking the performance of the GeForce GT 750M into account, 1600x900 pixels would be more appropriate (the display does a good job with interpolation at this resolution).

We already mentioned that the panel is highly reflective - which can be an issue no matter if the notebook is used outside or inside in brightly lit environments. Even though the brightness is more than adequate, the usability outside is hampered. A none-glare panel with the same brightness would definitely alleviate the problem.

The viewing angles are very restrictive. Even small deviations both in the horizontal and vertical plane cause a deterioration of the picture quality. The quality suffers especially when the panel is viewed from above and below.

Since One is planning to switch to a non-glare panel once available, we would recommend holding off on a purchase. Especially if Clevo should decide to use the LG Philips LP156WF1-TLF3 panel found in the W350ST barebone, the matte display would be a much more attractive option. Another alternative is the more expensive Schenker XMG M503, which lures prospective buyers with an IPS display panel.

Processor

Haswell
Haswell

Although the CPUs based on Intel's new architecture only see a minimal increase in performance compared to the previous generation, the Haswell processors are nonetheless the ultimate choice for gaming systems. Manufacturers particularly like the Core i7-4700MQ, which offers high performance at an acceptable price.

Just like the faster (by 300 MHz) Core i7-4800MQ, this particular quad-core model is equipped with 6 MB L3 cache and supports hyper threading, which enables the Core i7-4700MQ to process 8 threads at the same time. The CPU is manufactured using the 22 nm process and features a TDP of 47 watts (Ivy Bridge 45 watts), which seems acceptable considering the speed.

To curb the W650SR's appetite for power, Clevo uses Nvidia's Optimus technology. Dynamic graphics switching ensures that the GeForce GT 750M is only utilized when more powerful programs demand it. Otherwise, only the integrated HD Graphics 4600 sees duty.

Turbo Boost

We don't need to talk much about Intel's Turbo Boost technology - which automatically overclocks the CPU cores - since it does its job as expected. Regardless if one core or all cores are working: the Core i7-4700MQ overclocks to 3.1-3.4 GHz. Even during the stress test, we still saw 2.7-2.8 GHz.

CPU Performance

The CPU performance is more than OK considering the price of the notebook. The Core i7-4700MQ has an easy time with most applications and shouldn't be a performance-limiting factor for years to come.

Let's take a look at the results of Cinebench R11.5. Although the score of 1.51 points for the quad-core processor during the Single-CPU test is about 10% lower than the one for the Core i7-4800MQ (1.68 points, Schenker W503), it is nonetheless about 7% higher than the score of the older Core i7-3630QM (1.41 points, Asus N56VB-S4050H) - a CPU that features the same clock speed of 2.4-3.4 GHz. The Multi-CPU tests show more of the same: 6.96 points is almost in the middle between the Core i7-4800MQ (7.61 points) and the Core i7-3630QM (6.41 points).

Just like the popular GeForce GT 650M, the brand-new GeForce GT 750M is available in two versions. In addition to a DDR3 variant, Nvidia also sells a version with GDDR5 RAM. We don't want to raise false hopes: the One K56-3F has to make do with the 1800 MHz, 2048 MB DDR3 version.

A closer look at the specs shows the relationship to the lower-end graphics card siblings: 384 shader cores, 1.3 billion transistors, and a 128-bit interface are reminiscent of the GeForce GT 745M and the GT 740M.

The difference lies in the core frequency: instead of 810 MHz (GT 740M) or 837 MHz (GT 745M), the DirectX 11 capable GPU is clocked at a more robust 967 MHz. GPU Boost technology (automatic overclocking) allows the frequency to increase up to 1163 MHz under load. Our check with the GPU-Z tool shows that the GPU maintains this frequency even when running demanding 3D applications (see screenshot). 

The 28 nm manufacturing process guarantees a fairly moderate power consumption. The GeForce GT 750M is based on the GK107 chip, which was used in the GeForce GT 650M (also Kepler architecture). The new GPU doesn't threaten the GeForce GTX 760M in any way, since this high-end model features twice as many shader units (768 CUDA cores) and a 95% higher transistor count (2540 million).

GPU Performance

The GeForce GT 750M is a middle-class GPU. The One K56-3F didn't run the Unigine Heaven 3.0 benchmark test (1920x1080 pixels, details set to high, normal tessellation) fluently - although 22.3 fps is about 4% faster than what the GeForce GT 650M is capable of (21.5 fps, Schenker XMG A502) and 20% faster than what we recorded for the GeForce GT 740M (18.6 fps, Asus N56VB-S4050H). The less frequently seen AMD Radeon HD 8870M performs about 20% better though (26.7 fps, Samsung 770Z7E-S01DE).

The Fire Strike test - part of the 3DMark 2013 benchmark suite - shows similar results. The GeForce GT 750M scores 1574 points - about 20% better than the GT 740M (1316 points) and 24% slower than the GTX 760M (2060 points, Acer Aspire V3-772G). The GDDR5 version of the GeForce GT 650M scores 1572 points - an almost identical result.

AS SSD benchmark
AS SSD benchmark

Our review notebook came equipped with two hard drives. The first one, a 128 GB Toshiba HG5d THNSNH128GMCT mSATA SSD is - despite the small size - one of the fastest SATA III models we've ever encountered.

A sequential read speed of 501 MB/s (AS SSD Benchmark) is pretty common nowadays - but a sequential write speed of 462 MB/s outclasses most competitors. Only larger SSDs - like the Samsung SSD 840 Pro (~498 MB/s), the OCZ Vertex 4 (~459 MB/s), or the Corsair Neutron GTX (~456 MB/s) offer similar performance. The Toshiba SSD also handles small files very well and the access times of 0.11 ms (read) and 0.04 ms (write) are also top-notch.

In addition to the mSATA drive, our K56-3F came with a hybrid hard drive. SSH(D)s are a combination of a conventional hard drive and flash storage. Even though the performance doesn't come close to a full-fledged SSD, the 1000 GB Seagate ST1000LM014-1EJ164 is able to hold its own. Compared to regular drives, the hybrid models just feel faster. The fact that the Seagate drive spins at only 5400 RPM is not noticeable - it acts more like a high-performance 7200 RPM hard drive.

Thanks to the extremely quick SSD, the multimedia notebook garners the top spot in our database: 23558 points for the PCMark Vantage benchmark test is the highest score we've recorded to date. Even high-performance dual-GPU notebooks like the Schenker XMG P722 or the Alienware M18x didn't manage to break the 23000 point barrier. The score of the PCMark 7 test isn't quite as outstanding, as several notebooks surpassed it - including One's own K73-3N (6070 vs. 5905 points).

Gaming Performance

Full HD is too much at times
Full HD is too much at times

Our gaming benchmarks show that the GeForce GT 750M often struggles with the native resolution of 1920x1080 pixels. With details set to maximum and 4x anti-aliasing enabled, demanding games like Metro: Last LightCrysis 3, or Far Cry 3 don't run smoothly at all.

Even high details and 2x anti-aliasing prove to be too much at times. The only way to ensure decent performance is to reduce the details and resolution - sometimes medium details and 1366x768 pixels is all that's possible. Less demanding titles like Counter-Strike: Global OffensiveFIFA 13 or Dishonored run smoothly even at 1920x1080 pixels and details set to maximum.

Avid gamers are better off with a GeForce GTX 760M. This high-end card offers performance increases of up to 50%. The GeForce GT 750M performs similar to the older GeForce GT 650M (GDDR5 version). While the GT 745M is about 5% slower, the GT 740M lags behind by 10% (for the DDR3 versions). Our opinion: the GeForce GT 750M is a decent middle-class GPU and as such neither overly fast nor disappointingly slow.

A drawback: although the GPU is decidedly not high-end, the K56-3F gets quite noisy when tasked with 3D applications.

During the first scene of the 3DMark06 benchmark test, we measured 46 dB - clearly audible in normal environments. The Toshiba Satellite P70 (Core i7-4700MQ & GeForce GT 745M) - which offers about the same performance - doesn't get quite as noisy. Those playing with a headset or playing louder action-type games won't have too many issues getting adjusted to the noise though. The maximum recorded noise level of 51 dB only occurs when the system is subjected to maximum load levels. 

During idle and simple office-type tasks and web browsing, the 15-inch system remains surprisingly quiet. Aside from the subtle fan and hard drive noise, the all-rounder can only be heard when the ear is close to the system. The noise level of the DVD-RW drive also remains well-controlled: we measured 35 dB when playing a DVD.

One of the weakest points of the system: high temperatures. Compared to the barebone siblings P157SM und P177SM, the surface areas of the K56-3F get quite warm.

We measured 34 °C after two hours of idle time and 42 °C after running the stress test with Furmark and Prime in parallel for one hour. These results are comparatively high - although we have to admit that the ambient temperature was also fairly high when we conducted these measurements. Users who want to avoid high temperatures should take a look at other notebooks - the Asus N56VB for example.

The internal components also run rather hot: after running the stress test, the graphics card topped out at over 80 °C. According to the CPUID hardware monitor, the processor gets even hotter and reaches up to 95 °C. The hard drive temperatures of 40 °C (hybrid) and 64 °C (mSATA SSD) are also far from ideal. The power adapter reached 55 °C. Positive: during our tests we didn't encounter any throttling of the system.

Speakers

Since we couldn't get the Sound Blaster Cinema software to work even after several attempts ("no supported audio devices found"), we tested the 15-inch system without the benefit of Creative's sound improvement.

The sound of the two speakers, which are integrated into the front of the system, is quite uninspiring even for notebooks. Music especially sounds artificial, imprecise, and tinny - even though the maximum volume level is sufficiently high. The K56-3F also doesn't come with a subwoofer and the bass is correspondingly very weak.

There is no comparison: the multimedia competitors Asus N56VB and Samsung 770Z5E sound significantly better. In other words: to enjoy the sound of the K56-3F, headphones or an external speaker system are highly recommended.

Energy Management

Power Consumption

Nvidia's Optimus technology ensures moderate power consumption during idle. 11-20 watts is unheard of in the realm of potent gaming systems (Schenker XMG A523: 15-26 watts). While running the 3DMark06 benchmark test, the K56-3F consumed almost as much power as the 17-inch Toshiba Satellite P70 (83 vs. 84 watts). Maximum performance stresses the power supply - we measured up to 138 watts at the socket.

The battery life is more than adequate: the 62 Wh lithium-ion battery lasted between 2 and 5.5 hours (Battery Eater) - many competing systems don't come close. 

During the more realistic tests, the results are somewhere in-between - with reduced display brightness (50%), we were able to surf the internet for about four hours. The system quit the DVD playback test (maximum brightness) after about three hours. The W350ST barebone also has a decent battery life - thanks to its higher-capacity 8-cell battery.

Verdict

One K56-3F
One K56-3F (Herstellerfoto)

The One K56-3F is a somewhat mixed bag: The 15-inch multimedia system has its definite strengths like upgradeability, understated good looks, good input devices, and very decent performanceNvidia's GeForce GT 750M is not the highest performing GPU - but is a good option for price-conscious gaming aficionados and multimedia users.

Equipped with a Solid State Drive (either mSATA or a 2.5-inch model), the Windows experience is very enjoyable indeed. The reasonable size and weight of the notebook and the slim power adapter make for a very mobile system - and the battery life is decent to boot.

After spending more time with the notebook, some of its drawbacks became apparent. While the undesirable port locations or the lack of a keyboard backlight are only minor inconveniences and not a deal breaker, many buyers won't be happy with the subpar sound and the average display quality.

Even though the brightness of the display is high, the Full HD panel fails to impress. The viewing angles are too restricted, the black value too high, the colors not vivid enough: the display is rather disappointing in many areas. If One should - like announced - switch to a non-glare panel, many of those flaws might simply vanish. The insufficient sound quality and the high noise and temperature emissions are not likely to change however: the 15-inch system gets quite hot and loud when tasked with 3D applications.

For users looking for an unobtrusive and highly configurable all-purpose notebook, the One K56-3F is worth considering.
