Review One K73-3S (Clevo P370SM) Notebook

Florian Glaser (translated by Vinay Pradhan), 09/04/2013

Twin Guns. The One K73-3S is the best the mobile gaming market has to offer today. Thanks to dual high-end graphic cards, it leaves the competition in the dust. We put a model through our benchmark tests. Can the Radeon HD 8970M CrossFire set a new record?

For the original German review, see here.

One, the hardware expert, is famous for its powerful and uniquely configured notebooks. The K73-3S is extensively configurable like its previously tested siblings: K33-3E (GTX 765M), K56-3F (GT 750M), K56-3N2 (GTX 780M) and K73-3N (GTX 770M).

Let us start with the CPU: One offers the Core i7-4700MQ (2.4-3.4 GHz), the  Core i7-4800MQ (2.7-3.7 GHz), the 4900MQ (2.8-3.8 GHz) and the 4930MX (3.0-3.9 GHz). The last one is not recommended as the increased performance it offers by no means justifies its price and one of the slower and cheaper models will suffice, even for a dual-GPU system like the Radeon HD 8970M CrossFire. Now on to the graphic cards: although One has chosen AMDs top guns, the barebones should theoretically be capable of accommodating dual GeForce GTX 765M or GTX 780M cards.

The RAM (four slots) ranges between 4 - 32 GB DDR3 RAM (each running at 1,600 MHz). The laptop can accommodate multiple hard disks: the 17-inch case offers two mSATA slots and two classical 2.5-inch slots. While One uses Toshiba for the mSATA SSDs, the larger 2.5-inch SSDs come from either Kingston or Samsung. Hybrid models and conventional HDDs that run at 5,400 - 7,200 rpm can also be found on the homepage.

An Intel (Centrino N 2230/6235) or Qualcomm Atheros (Killer N 1202) module serves the users wireless needs. The DVD drive or Blu-ray drive take care of the reading of optical media. An operating system is not included in the 1,600 Euros (~$2108) basic packet, but can be bought for a little extra (Windows 7 & 8).

The gaming notebook is based on the 419 x 293 x 54 mm (~16.5 x 11.5 x 2.1 inch) and 4 kg (~8.8 pound) Clevo P370SM Barebones heavyweight, which is also sold by other manufacturers like Schenker. Detailed information about the case can be found in the XMG P723 review.

Connectivity

Interfaces

Aside from the Thunderbolt interface, which was not in the P370EM barebones, the connectivity does not have any surprises. The notebook is equipped with Gigabit-LAN port, an HDMI interface, an eSATA/USB-2.0 combo and a 9-in-1 card reader. The manufacturer deserves respect for the four audio jacks (analog 7.1 sound & S/PDIF) as well as four USB-3.0 ports.

As most ports are placed near the rear of the notebook, the use of an external mouse does not cause any problems. The security features include Kensington Lock, a fingerprint reader and a TPM 1.2 chip.

Wireless Communication

Our test model is equipped with the Intel Centrino Wireless-N 2230 (which is the basic model). The half-length PCIe module supports only the 2.4 GHz frequency (5.0 GHz is only available starting with the Advanced-N 6235) and data is transferred at up to 300 Mbit/s. As expected, Intel has certified the WLAN standards 802.11 b/g/n. Bluetooth 4.0, Wireless Display and Smart Connect are included in the repertoire. The range of the module was not great in our test. Other laptops have performed in this area.

Maintenance

The maintenance possibilities are exemplary and are identical to those of the Schenker XMG P723. In that review, we explore what lies under the maintenance flap and how to remove the keyboard.

Software

The software is spartan. One has avoided the annoying Bloatware most manufacturers favor and provided the user only the necessary drivers and a test version of Office 365. We found it rather strange that our test model lacked the sound suite SoundBlaster X-Fi MB3 and the graphics driver.

Although our test of the Radeon HD 8970M reveals the dangers of the official AMD driver, we chose to install the brand-new AMD Catalyst 13.8 Beta2. The Clevo driver provided by the manufacturer (found on the drivers DVD) should prove more reliable but slower in the latest games.

Accessories

In addition to the previously mentioned drivers DVD, One offers a multilingual manual, a cleaning cloth and a hard disk kit (screws, protective flap) in the delivery. Buyers of a Samsung SSD will be pleased with the extras such as a warranty notice, an installation manual and a tool DVD. The 1.2 kg (~2.6 pound) 330 W power adapter and the heavy 450 gram (~1 pound), 8-cell battery are standard for the P370SM Barebones.

Warranty

Depending on the need, the warranty can be extended from 12 to 24 or 36 months (+50/+180 Euros, +~$66/+~$237). The Pickup & Return Service offers a similar plan. 

Input Devices

The input devices left us with mixed feelings. On the positive side, the three zones that light up the keyboard allow the user to comfortably type in the dark. However, the unusual key placement requires some getting used to. Furthermore, the spongy touchpad does not inspire confidence and its glossy surface prevents us from working comfortably. The XMG P723 review deals with this matter in-depth.

Display

The case manufacturer Clevo does not gamble when it comes to the display. They have once again chosen the extremely popular Chi Mei N173HGE panel. Although professional graphics editors will be unhappy due to the color differences, poor saturation and inaccurate gray levels (see CalMAN screenshots), most "normal" users will be happy due to the excellent brightness (average of 320 cd/m²) and high contrast. A contrast of 750:1 is hard-to-reach for an 08/15 panel, but other models with the Chi Mei N173HGE panel can achieve more than 900:1 (like the MSI GT70H).

An illumination of 87% and a black value of 0.46 cd/m² are not new records but these do offer a well-lit interface. However, in dark scenes, the picture is tinted gray. Thankfully our test model does not suffer from the horizontal "bands" the Schenker XMG P723 (Radeon HD 8970M) is plagued by. As we suspected, this was due to the combination of an Nvidia GPU and no graphics switching (the Asus G750 is also affected). Sadly, "the grainy finish" remains.

Regardless, one can work comfortably with the screen. The large surface and Full HD resolution of 1920x1080 pixels provides enough room for working with multiple programs.

Outdoors, this 17-inch laptop leaves no room for complaint. The great illumination allows the user to enjoy using the notebook in the sunlight. However, the viewing angles are restricted under extreme conditions (see gallery).

For TN standards, the viewing angles are quite good. If color deviations are ignored, the horizontal viewing angles remain satisfactorily stable. Vertically, the display should not be pushed too far back or too far to the front. Overall, the screen merits a "Very Good" rating.

Processor

The One K73-3S is a quad-core CPU from the Intel Haswell generation. We chose the Core i7-4800MQ, which is also used for the review of the Schenker XMG P723. The clock speeds of the processor are 2.7-3.7 GHz and it runs around 300 MHz faster (on paper) than the cheaper Core i7-4700MQ, which also has a 6 MB L3 cache (Core i7-4900MQ: 8 MB).

Aside from the Core i7-4930MX, the TDP of the model is 47 W. The manufacturing process produces Haswell CPUs identically in the 22 nm format and indicates a modern product. Due to the dual-GPU option, the integrated DirectX 11-ready HD Graphics 4600 IGP remains off. It does not matter if its Nvidia or AMD, a graphics switching option is just not provided on the P370SM barebones.

Turbo Boost

In contrast to the Schenker competitor, which we tested with the weaker GeForce GTX 765M SLI combo, the CPU overclocking of our test model is not as well developed. While the Core i7-4800MQ clocks between 3.4 - 3.6 GHz in Single-Core benchmarks, it can achieve between 3.3 - 3.4 GHz in Multi-Core tests. Theoretically, it is possible to achieve up to 3.7 and 3.5 GHz respectively. Depending on the benchmark, differences in performance might be noticeable when comparing this model to other devices that run on the Core i7-4800MQ. In our test, no throttling was noticeable. Only at full load, does the One test model get stuck at 3 GHz.

CPU performance

At the beginning of this review, we said that it would not be wise (from a price-to-performance point of view) to invest in the fastest processor available for this test model. We will now prove this using scores from Cinebench R11.5. The test model achieves 1.63 points in the Single CPU test, which is quite good, but this is a mere 9% higher than the score of the Core i7-4700MQ (1.5 points @ One K56-3N2). With 7.09 to 6.9 points, the lead in the Multi-CPU benchmark decreases further.

The 300 Euros (~$395) more expensive Core i7-4900MQ runs 4% (1.7 points @ Schenker XMG P703) and 5% (7.45 points @ Clevo P150SM) faster. This is not much of a lead and in the opinion of the author, the avid gamer should stick to the Core i7-4700MQ or 4800MQ.

Graphics Card

Clock speeds 3D

The Radeon HD 8970M is merely a slightly modified version of the Radeon HD 7970M. It runs a bit faster (900 MHz @ core, 1,250 MHz @ VRAM) and offers - at least in Clevo - double the video memory (4,096 MB GDDR5), which is connected to a 256-bit interface. The 28 nm GPU also has 1,280 shaders and 2.8 billion transistors (GeForce GTX 780M: 3.54 billion).

It gets much more exciting when you put two such HD 8970M GPUs in one case using the CrossFire technology. Like the Nvidia SLI, the technology allows the user to harness massive performance, but it comes at the price of annoying flaws caused by the dual-GPU system. The system requires a lot of room, ventilation and power (heavy case, loud emissions and short battery life). Furthermore, this system is heavily dependent on drivers.

This is the area where AMD has been lagging behind Nvidia for years. This can lead to unexpected issues while gaming (see list in Gaming Performance). Thanks to the better driver support, SLI works much better and offers much more power from the second GPU.

An important new update is the so-called "Frame Pacing" (activated per default), which AMD has built into their drivers recently. This improvement is meant to deal with "micro-stutters" which pop up at low frame rates and can spoil the gaming experience. Due to the enormous performance of a CrossFire system, it is hard to find a game that runs at low frame rates.

Frame Pacing
Frame Pacing

Update: We took a closer look at "Frame Pacing". According to AMD, it is supposed to massively reduce the frame gaps, which occur when dual-VGA systems alternately process data (AFR method). This new feature can be easily turned on/off in the 3D program performance settings of the GPU driver.

A short test with BioShock: InfiniteMetro: Last Light and Hitman: Absolution reveals that the performance with active Frame Pacing only drops by 1%. Thanks to the good frame rate, all games run fluidly and Frame Pacing rounds off the experience (subjective). As Fraps is not optimal to measure this effect, the reader should read our graphs with a grain of salt (only an FCAT system can offer reliable results).

GPU Performance

Synthetic graphic benchmarks are a piece of cake for the One K73-3S. The results of the DirectX 11 tests are especially impressive. A Fire Strike GPU score of 10,354 points cannot be reached by a single GPU. Even with the latest WHQL driver (320.49), the GeForce GTX 780M loses by around 45% (5,744 points @ One K73-3N). A single HD 8970M card can process 3DMark 2013 only half as fast (5,110 points @ One K73-3N).

In the Unigine Heaven 3.0 benchmark (1920x1080, High, Tessellation normal), the dual GPU system performs similarly. 123 fps is an extra 14% over the GeForce GTX 680M SLI (108 fps @ Schenker XMG U702). While a GeForce GTX 780M runs about 40% slower (~77 fps), a Radeon HD 8970M reaches about exactly half (~61 fps). In older DX11 and DX9 benchmarks, the difference between the GPUs is not as great.

AS SSD Benchmark

The operating system was found installed on a 500 GB Samsung 840 SSD. Although One did not choose high-quality MLC storage (standard is TLC storage), the Samsung 840 is a good choice for gamers as it is faster than traditional HDDs.

The SATA-III model does not have to hide from the competition. 518 MB/s in sequential read tests of AS SSD benchmark earns the drive respect. The sequential write rate of 340 MB/s is "merely" good. Some competitors, like the OCZ Vertex 4, offer over 400 MB/s.

In everyday use, the performance with small files is important. Thankfully, the Samsung drive had no problems with this task. The access time is 0.11 ms (Read) and 0.03 ms (Write) - no reason for complaint. Those who have the money should pick the Pro version (longer life).

System Performance

It is not surprising that the system performs at a high level. 20,125 points in PCMark Vantage indicate a strong, balanced system. Other high-end notebooks, like the MSI GT70H (20,318 points) or the One K33-3E (20,174 points) can only reach these high levels thanks to their respective SSDs.

In PCMark 7, the test model continues this positive trend. A total result of 5,412 points allows the 17- inch notebook to overtake the Alienware M18x R2, which runs on the Core i7-3920XMtwo Radeon HD 7970M GPUs and a Micron RealSSD C400.

Gaming Performance

Almost all games ran at max details.

As long as the appropriate profile is picked, every modern game should run with all options set to max, active anti-aliasing and Full HD resolution. Of the 28 tested games, only Company of Heroes 2 stuttered very heavily. Even games like Crysis 3Metro: Last Light or Hitman: Absolution run at more than 35 fps (Ultra settings).

It is not only due to the driver update that the dual-GPU system performs 10% faster than the GeForce GTX 680M SLI and 30% faster than the Radeon HD 7970M CF. A GeForce GTX 780M is about 20% slower. The lead over a single HD 8970M is significant: 33% leaves plenty of breathing space. In contrast, SLI systems are far more efficient (50+).

If we ignore the negative anomalies, the performance gain is a lot higher as can be seen from the tables at the end if this review. In most cases, the CrossFire duo processes 40-100% faster.

As we expected, while testing the AMD GPUs, we found a lot of anomalies, which should be corrected by future drivers:

 

  • Alan Wake: heavy graphical errors regardless of settings
  • Anno 2070: performance fluctuations in the main menu
  • Assassin's Creed III: still poor performance in comparison to Nvidia
  • Far Cry 3: stuttered at maximum settings despite a good frame rate
  • FIFA 13: poor shadows
  • F1 2012: lower speeds when using an external display and FPS fluctuations while using the internal display.
  • Guild Wars 2Counter-Strike: Global Offensive and FIFA 13: slower than with a single GPU
  • Sleeping Dogs: hangs at start and causes an undesired restart
  • Other: in most games, the display flickered. Changing and launching windows often showed graphical errors. Some easy tasks were better performed by a single GPU. In addition, there were sporadic drops (for example, in the Cloud Gate test of 3DMark 2013). Also ugly: while idle, the second HD 8970M runs at full speed and 99% load (according to GPU-Z).

Emissions

System Noise

Like the predecessor, the P370SM barebones has high noise emissions. An average of 38 dB(A) while idle is unnecessary and indicate poor ventilation. Sometimes the value rises to 41 dB(A), which is a far more audible level. The DVD burner emits 40 dB(A) while playing DVDs.

In 3D mode, the K73-3S runs slightly louder. 46 dB(A) in the first scene of 3DMark 06 and 53 dB(A) at full load are very loud. Depending on the genre and volume of the game, the emissions might drown out the game noises. Only with a headset is it possible to enjoy the games in peace. Despite the weaker GeForce GTX 765M SLI, the Schenker XMG P723 was similarly loud.

Clevo seems to regulate the fan speeds primarily based on the load and temperature. This impression was gleaned from our test of the Radeon HD 8970M. We hold out hope that one day Clevo will take another look at their cooling system, as other manufacturers, like MSI (GT70) or Asus (G750) integrate far better cooling.

Temperature

Stress test
Stress test (Furmark & Prime)

The temperatures are very moderate. While the case settles around 31 °C (87.8 °F) at full load, in idle mode, it barely reaches 28 °C (82.4 °F). Those users who did not pick hot 2.5-inch drives (the XMG P723 serves as a negative example), can enjoy surprisingly cool hand-rest regions.

Even the fan regions do not heat up uncomfortably during 3D mode. At a max of 35 °C (95 °F) above and 41 °C (105.8 °F) below, the emissions are very good. Long gaming sessions are not a problem with our test model, whereas compact/lighter models like the MSI GE70 or the One K33-3E have far higher temperatures.

Thanks to the fast fan, the hardware is in no danger of dying out due to heat. It is sad that the CPU reaches 90 °C (194 °F) despite inactive Turbo Boost in the stress test (FurMark + Prime95), but this is somewhat balanced out by the two GPUs which reach about 82 °C (179.6 °F, primary GPU) and 56 °C (132.8 °F, secondary GPU) after about an hour of the same test. The far lower temperatures of the second GPU leave some doubts about whether One is optimally using the secondary GPU.

Once again, we forward the reader to the review of the Schenker XMG P723

Energy Management

Power Consumption

The idle consumption is close to that of the GeForce GTX 765M SLI. Due to missing graphics switching, the K73-3S will always require more than 30 W. 35-47 W while idle are far from ideal.

At load, the consumption is above average. The laptop pulls about 159 W from the socket while running 3DMark 06. The max value is 226 W. The test configuration of the XMG P723 settled for 123 W (-23%) and 208 W (-8%), which is around the level of the smaller sibling, the XMG P703 (128/209 W @ GTX 780M).

Battery Life

Reader's Test
Max battery life (Reader's Test)

Minimum run time (Classic Test)

A good battery life should not be expected of the K73-3S. Like the XMG P723, the powerful Lithium-Ion battery (89 Wh, 5,900 mAh) is empty after 3 hours. One hour of gaming or 2 hours of DVD playback is hardly ideal. If the CrossFire could have been turned off, the run times would have been much longer.

Verdict

One K73-3S
One K73-3S

Gaming enthusiasts, who want a powerful high-end notebook, can truly enjoy the One K73-3S. The 4 kg (~8.8 pound) chassis scores thanks to its cool surface temperatures, backlit keyboard, easy maintenance and good connectivity. The decent sound and bright Full HD display are additional strengths.

The performance is not lacking in the 17-inch model. An SSD allows the model to run very fast. Gamers will primarily be happy about the huge gaming prowess. Only a few notebooks offer similar performance.

Unfortunately, the AMD driver is not perfect. Graphic errors and performance fluctuations are not part of any description of an ideal GPU. Those users who want to be on the safe side should use the Clevo driver or pick an Nvidia system, as this main competition offers a much more balanced performance with their SLI system and drivers.

The battery life, touchpad and the noise emissions were not satisfactory either. Regardless whether idle or in gaming mode: the fan runs very loudly. The heavy weight and chunky build prevent us from rewarding the model a better score. 

Note: the GeForce GTX 780M SLI will be tested soon in the Alienware 18.
