Clevo P151HM / CyberPower X6-9300 Gamut


MSI GT680R Gamut

As mentioned earlier, the LCD on the MSI laptop is noticeably inferior. The sad thing is that both the MSI and Clevo use the same AU Optronics B156HW01 LCD panel, but Clevo uses v1 while MSI uses v5. Presumably the v5 panel is a lot cheaper—at least it better be, judging by the results shown above!

On the other hand, the P151HM has what is very likely the best laptop LCD I’ve used in most areas. An 800:1 contrast ratio is great for a matte LCD, color accuracy is reasonable, and color gamut is close to ideal for the sRGB space. If you’re after a high gamut panel, there are better options, but most people feel high gamut panels just end up looking oversaturated. I really wish we could draw a line in the sand and have the P151HM panel set the minimum quality level that laptop displays should reach, but instead we have a race to the lowest priced LCD notebook manufacturers can find, which is why we see so many 1366x768 laptops.

Not only does the Clevo notebook offer superior contrast, but it also offers better viewing angles. We’re still dealing with TN panels either way, which is unfortunate but difficult to avoid, but the P151HM has a much wider sweet spot for viewing.

Noise and Temperatures

CPU temperatures are about 5C lower on the Clevo when the system is under a heavy load for a long time, but the GPU runs reasonably cool in both notebooks. The catch is that the Clevo only manages this by ramping up fan speeds much earlier than MSI.

At idle, the MSI GT680R maintains a constant 34.5dB output (for around 12”); in contrast, the Clevo oscillates between 31.9dB and 35.6dB. What’s truly unfortunate is that the Clevo is the more annoying under light workloads because you notice the frequently changing noise level more than you would a steady drone. Under load, the noise situation falls even more heavily in MSI’s favor. After looping 3DMark06 at 1080p for over 30 minutes, the MSI still maintained a reasonable output of 39.1dB, and it would even drop to 36-37dB at times. The P151HM on the other hand quickly ramped up fan speed to what appears to be the maximum RPM, putting out a loud 44.3dB. Under our worst-case load (4-thread Cinebench with 3DMark06 looping), the MSI also had to increase fan speed to 44.0dB and the Clevo maintained the same 44.3dB output, but most users likely won’t be putting a 100% load on all CPU cores while loading the GPU at the same time.

Looking at the cooling arrangement, MSI actually does something quite useful. The chassis at first appears to have a rear and side vent, but it turns out the rear vent is actually an air intake. Instead of trying to pull air through the bottom of the chassis like most notebooks, the fan gets easy access to fresh air at from the back, and vents it out the left side. ASUS’ G73 chassis is still the quietest gaming notebook we’ve encountered (though we’re not sure if that translates well to the smaller G53 chassis), but the MSI cooling arrangement tends to work well. It would be nice if they could reduce idle noise levels a bit more, but a steady 34dB is better than hearing the fan spin up and then slow down ever 10-20 seconds.

    One of the grad students I work with just bought an XPS 17 with the 3GB 555M for doing CUDA work, it has the 144 shader/DDR3 version of the 555M. Also, there don't seem to yet be proper drivers for using CUDA 4.0 with Optimus

    I'm waiting for a high end gaming notebook with a sandy bridge core i7 quad core cpu, dual high end gpu's, and a 120 Hz IPS screen. Is that so much to ask?
  • tmacfan4321 - Saturday, May 14, 2011 - link

    Is the Alienware M18x not good enough for you?

    BTW, 120Hz IPS displays are rare in monitor form. You're dreaming if you think that laptop manufacturers are going to be able to pull that one off.

    and of course, a backlit keyboard.

    holy jeebus MSI GT680R is one ugly computer... :S

    And on that note, I really like the simplistic and clean "no design" of the Cyberpower's case. If they had only skipped the glossy besel and had a backlit keyboard and maybe a little bit bigger touchpad, it would have been a really nice computer.

    If I owned an HM150, I'd probably take out the LCD and sand down the bezel. It would make the laptop a lot more aesthetically pleasing.

    Looks like there's a missing paragraph under the photo gallery on the first page

    Oops, sorry it's on the Doing the time warp page....

    Why is it, that RAID 0 constantly is referred to in reviews like this, when every article or test I have ever read - your own here at Anandtech inclusive -ends up stating, that it has only theoretical effect, if any.

    The Lenovo W520 hits on about all of those features that the author wants in a laptop with the exception of the price and sound quality. I ordered a heavily discounted W520 for $1500. The specs were as follows: i7-2720QM, NVIDIA Quadro 2000M with Optimus (GTX 460M with 128-bit bus), matte FHD screen with 95% color gamut (same panel as the RGB-LED Dell LCD), 4GB of RAM, 500GB 7200RPM HDD.

    The backlit keyboard isn't there, but there is the ThinkLight on the top of the display. The GPU is slightly slower than the GTX 460M because of its 128-bit bus and its Quadro BIOS. The battery life is awesome, due to Optimus. The build quality is stellar because it's a Thinkpad.

    Normally that config will run you around $2000. That's the only problem.
