Mythlogic Pollux 1613 / Clevo P157SM Subjective Evaluation

Since Mythlogic uses Clevo notebooks and simply customizes them, the core hardware has a lot in common with previous Clevo notebooks that we’ve reviewed. That can be both a blessing and a curse, but they do offer up some interesting new options, along with the usual selection of CPU, GPU, RAM, display, and storage choices. While the performance of any particular notebook depends largely on the choice of CPU and GPU (and SSD vs. HDD), subjectively what we think of any notebook often has a lot more to do with things like the display, keyboard, touchpad, and general build quality. Here’s another set of images of the P157SM, this time taken by yours truly:

Chief among optional extras is that Mythlogic will install a different keyboard in the chassis (provided they have keyboards in stock, apparently), which addresses some of the complaints we’ve had with previous Clevo keyboards. In practice, the changes aren’t all that significant; the modified keyboard has chiclet style keys while the standard Clevo keyboard has beveled/ridged edges. You can get an idea of the difference by looking at images from our test notebook compared to the standard keyboard. The alternate keyboard is, as far as I can tell, identical to the MSI SteelSeries keyboards used in the GT60 and GT70 notebooks—though obviously they can’t use the SteelSeries branding—with the only real change being the Fn and Start keys have swapped positions. There’s also colored keyboard backlighting, and you can adjust the colors using a utility that you get by pressing Fn+[Keypad /]—and again, this is identical to the backlighting on the MSI GT70 and other modern Clevo designs.

Note that since the keyboard is not the default Clevo design, some of the Fn key combinations are not what you see on the keys—so Fn+[Left Cursor] doesn’t reduce the volume; you’ll need to press FN+F5 for that instead. Mythlogic includes a reference sheet with all of the Clevo shortcuts, and as you spend time with the Pollux 1613 you’ll adapt—or you can just go with the standard Clevo keyboard. The feel of the MSI/alternate keyboard is very good, and it looks like the stock Clevo keyboards have finally fixed the 10-key and made it a standard layout (with a slightly narrower Numpad-0 key). Given the choice, I’d probably just stick with the stock Clevo keyboard now, but whichever way you got there are still aspects that aren’t necessarily ideal.

Specifically, the keyboard still has some issues with layout and key assignments, and the lack of dedicated Home and End keys is bothersome to me.  You need to use Fn+PgUp/PgDn to get those, which thanks to the right-hand location of the Fn key means using the right hand and stretching to reach both keys, or else move your left hand over to press Fn while you use the right to hit PgDn/PgUp. (Having Fn on the left side of the keyboard like most laptops would have helped, which is what MSI does on their notebooks with the SteelSeries keyboard.) Thankfully, there are utilities that allow you to remap most keys (Fn being the one exception), so you can assign Home and End to some other keys that you don’t use much, like Scroll Lock, Pause/Break, or Insert. Ideally, though, I’d prefer to have the current Pause/Break become Delete, then assign Home and End to the current Insert and Delete locations, with Fn combos providing access to Pause/Break and Insert for those that need them. I’d also shift the extra Backslash over to the left of the Space and have it function as either Fn or the Start key, and then the current Fn key location could provide the Context function (Shift+F10). Of course, this is all personal preference so others might be happy with the current arrangement. YMMV.

The biggest flaw with the latest Clevo generation is next, and it’s the touchpad. Previously I’ve seen plenty of decent touchpads on Clevo, but this time around they apparently skimped out and went with a Sentelic solution. The few times I’ve seen Sentelic touchpads have been very painful, and while this is actually much better than previous hardware it still feels a bit sluggish and unresponsive. Most of the multi-touch gestures work fine at least, but even with the “On-pad Cursor Speed” set to maximum (Level 10), it’s nowhere near what I’m used to with touchpads. The result is that just to get the cursor from the bottom/left to the top/right of the display requires no fewer than four swipes of your finger—and if you’re not careful, instead of a swipe you’ll activate one of the Windows 8 gestures and bring up the Charms menu or switch applications, resulting in additional swipes. (Changing the Windows pointer speed thankfully fixes this, and with it set at about 70% I was much happier – it seems the Sentelic “On-Pad Cursor Speed” just doesn’t work right now.

Anyway, the included touchpad works well enough, but I think Clevo should have done more research before going with the Sentelic touchpad. It feels like a decision a bean counter made rather than something to benefit the end users. For a high-end notebook, it’s just not okay to continue cutting corners on little items like the touchpad. My advice is to make sure you bring along a mouse, particularly if you’re planning on playing games, but that almost goes without saying. I’ve mentioned this before, by my personal hierarchy of touchpads in order of decreasing quality is: Synaptics, Elan, Alps, and then Sentelic (though I may have missed a couple of the smaller players in that list). Interestingly, the P150SM and P170SM go with a Synaptics touchpad instead (sans backlighting), and Mythlogic will replace the touchpad with a non-backlit option if you want (but still Sentelic), which is great as I could see more than a few users being turned off by the “tramp stamp” on the touchpad.

For the display, Mythlogic lets you choose between a standard matte 1080p display or a high gamut 1080p offering; it’s only $35 extra for the 95% NTSC gamut panel, and I personally like this panel a lot. It’s the AUO B156HW01 v4, which I’ve reviewed a few times already in other laptops, and it still impresses compared to most other options. I’d like to see better IPS or AHVA panels instead, but the truth is most of the current notebook IPS panels are using WLED backlighting, so you get improved viewing angles but a much lower color gamut, with a higher price as well. Until we start seeing higher quality backlights on the IPS/AHVA laptop panels, a good TN panel with a high gamut backlight is at least a reasonable alternative.

Everything else is decent if not exceptional. The build quality and aesthetics are standard Clevo fare, which means there’s a lot of plastic with some slight flex if you press hard on the chassis. I’m not sure if the bezel is standard fare or if it’s something Mythlogic customizes, but it’s thankfully matte plastic this time and goes well with the matte LCD. Mythlogic did customize the lid on our review sample with their carbon fiber wrap, which is a $150 extra. It adds some visual flare to an otherwise black and nondescript design, but it shows marks and scratches more than the standard cover and for the price I think most users will be fine with the soft-touch coating Clevo uses. The use of plastic for the chassis also means that the surfaces don’t tend to feel too hot, even under sustained loads—only directly under the CPU and GPU will you notice hot spots, as well as on the rear exhaust ports.

Audio quality is likewise good if not great—though somewhat surprising to me is that even at maximum volume the notebook doesn’t get all that loud. (I was testing this at the same time as the Acer R7 and Acer V7, both of which put out more volume.) The P157SM does have a subwoofer that helps with lower tones, but at one point I had some friends trying to listen to an audio book and they felt it wasn’t able to get loud enough. In a quiet environment it’s okay, but if there are other people around that are talking or laughing then you’ll likely also wish for increased sound output levels.

As you’d expect from a system that’s designed to be customized by notebook vendors, getting at the internals of the P157SM is quite easy. There are four screws (two on the bottom, two on the back) that you need to remove, and then you can pull off the bottom panel that provides access to the HDD/mSATA slots and two of the SO-DIMMs, as well as the CPU and GPU. You can see the CPU upgrade process in the gallery above as well. The other two SO-DIMM slots are located under the keyboard, which can be a bit more of a pain to access but it isn’t too difficult. I’d like to see Mythlogic populate the two less accessible SO-DIMMs first, but perhaps it’s more stable with the bottom slots occupied than the reverse.

In my mind at least, Clevo has never been about the latest in design and aesthetics; if you want something flashy or with higher quality/higher cost materials you’ll want to look elsewhere. Instead, Clevo is typically focused on providing as much performance as possible in a reasonably inexpensive chassis, with a thicker casing allowing for improved cooling. The MSI GT60/GT70 are very similar in a lot of ways, but Clevo uses two cooling fans instead of a single HSF – one fan/heatsink for the CPU and chipset, and the other for the GPU. The result is lower temperatures and likely improved longevity, and with the keyboard layout now mostly fixed the only real question is how the Clevo P157SM performs. So let’s hit the benchmarks….

    It is strange that in some cases you had lower performance overclocked than not. Did you raise the TDP limit when you overclocked the CPU? I have found hitting the TDP limit to cause the CPU clocks to periodically plummet on my P150EM, hurting performance substantially.

    Ex 1:

    CPU is set to 3.8ghz, using 55W of power. CPU runs at 3.8ghz constantly, but only 3.5ghz is needed to max out the GPU in whatever game is being played at this time.

    Ex 2:

    CPU is set to 4ghz which requires the TDP to be over 55W. CPU usually runs at 4ghz, but every 10 seconds plummets to 2.6ghz. Since this particular game only needs a constant 3.5ghz, there is a performance loss.

    Yeah, in the BIOS I set it for 67W I believe. I don't know how much that affects things, but something else is clearly going on. GRID 2 in particular is very consistent with its odd behavior. Reply

    Didn't you say that one of the MSIs came with a 4930mx? You could pop that into the P157SM, set the TDP sky high, set the same clocks, and see if it has the same odd behavior.

    And upon taking off the clevo CPU heatsink you will see that they crush the heatpipes onto the heatsink plate, warping the plate raising temps by 10C+ (I lapped the plate on my P150EM). You can see stress marks in the plate directly under the heatpipes. GPU plate has the same problem. Clevos would have phenomenal cooling if clevo fixed this.

    The MSI systems had to go back to NVIDIA (for PAX), so I don't have them any longer. I'm not sure there's that much thermal headroom on the P157SM anyway -- temperatures notwithstanding, the 4900MQ overclocking is clearly hitting some limit that's preventing maximum performance. Reply

    I've been seriously considering the P150SM. Any real downsides in your opinion compared to the P157SM? I like the smaller size and that stupid touchpad light isn't present.

    I have been considering the exact same spec you reviewed (thanks by the way), but with 4x4gb 1866mhz RAM.

    If you're okay with the single 2.5" drive, I don't know that there's anything wrong with the P150SM. Given the touchpad and a few other aspects, I'd probably go that route myself if I were in the market for a gaming notebook... well, that or I'd opt for the larger P170SM. Reply

    All units of the P150SM I've found only had 120W power adapters. Do you see that as an issue? Reply

    XoticPC defaults to a 180W with the P150SM Reply
  • cmikeh2 - Friday, August 30, 2013 - link

    My bad I totally blanked there.. You're right. I was conflating P150SM with P151SM1 for some reason. Reply
  • Khenglish - Friday, August 30, 2013 - link

    180W is still too weak for overclocking. The 17 models come with a much more appropriate 220W PSU (which also can be too weak with heavy overclocking, but far better than 180W). I don't know why clevo chooses to gimp the 15 inch models with the smaller PSU connector and 40W weaker PSU. Reply
