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….

    What he said for the GPU. As for mSATA, there are two mSATA positions in the P157SM, so you can use two mSATA and two 2.5" HDD/SSDs. No idea on the cooling and turbo stuff for MSI, but I'd guess they're all the same in terms of features; maybe someone else has a better answer.

    For the performance differences, it could be drivers, it could be firmware optimizations, and it could be differences in maximum sustained Turbo (due to differences in cooling). On the desktop we're at the point where if you use the same CPU and GPU, performance is basically identical within a few percent, but on laptops there's still a lot more variation. Hope that helps.

    Hey Jarred, you wouldn't happen to be getting an ASUS N550 in anytime soon, would you? Reply

    I'll request one, but at present no laptop from ASUS is in route. Reply

    I am still a bit puzzled by the inability of the single-fan solution of the MSI GT series to do well by Haswell+GTX780M. I have an old MSI GT663R and it keeps a 920XM @ 3.2GHz and a 7970M under control in prime+furmark, no throttling, CPU at 95C max, GPU at 87C. With a 820QM and the same vid card, it's around 85C+85C in the same scenario - and Clarksfield is a hot processor. I also owned an HP 8740W, and its single-fan solution was capable of cooling well a 920XM and a Quadro 5000M (also prime+furmark).

    So why this sudden weakness with the GT60 and GT70? (Also worth noting that the dual heatsinks on my GT663R are much heavier than the dual heatsinks on the Clevo P150EM I owned for a short while, while the fan is bigger and more potent than any of the two Clevo fans, though the Clevo did cool well too.)

    Haswell is the same process as Ivy Bridge, so it's not really any cooler running -- it's just able to go into lower power states more quickly, more or less. In fact, it may run slightly hotter (not sure), all things considered. At present, the GT70 isn't throttling -- it's just running hotter than we'd like. Is it worth considering? For the right price, and if you like the styling more than the Clevos, sure. I don't think it's better, and you can get heavier copper heatsinks for Clevos from some vendors (XoticPC for instance), but go with what you think is best. Reply

    I have an order with Sager for a NP8258 (= Clevo P157SM). The original LCD panel was the 95% NTSC Gamut matt finish panel. I was just notified by Sager that this panel is no longer available due to "quality problems".

    Does anyone have information on what the problems are with this panel? Its been around for a pretty long time now, I don't know why they should begin experiencing quality problems at this point...

    Also, I replaced this panel with the standard FHD matt finish panel. Anyone know if this this is a decent LCD? It was only $35 less than the 95% NTSC Gamut. I loaded this laptop up to the gills and am paying a lot of dough for it. I really don't want to be stuck with a subpar LCD.
