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….

    Obvious answer is the tradeoff with the weight. If you overclock to the extent that you need 220W+ then you are going to need heavier duty cooling design which adds even more weight.
  • Khenglish - Saturday, August 31, 2013 - link

    The 15" and 17" laptops both have identical motherboards with Identical cooling (the 15" has a default aluminum CPU radiator, but most resellers offer the copper version found in the 17")

    So no there would be no extra weight.

    I, for one, am always glad to see high end displays in use. Props to Clevo for such a decent display.

    On your last page, you mention wanting to test against the Alienware 17. While I understand the reasoning, I think that Alienware/Dell put the majority of their focus on the 14 and 18 this time around. Both the 14 and 18 have high end display options that the 17 doesn't get. IPS, and PLS to be exact. Frankly, I would be far more interested in your results on those over the 17" TN panel.

    Also, I have a 9700QM based machine being delivered later this week - one thing I didn't see mentioned, was the thermal impact from overclocking. Also, is the 2bin OC limit an Intel limit, or BIOS limit? I know the machine I am picking up is supposed to allow overclocking, but I prefer not to go into these things blindly - and there really isn't a lot of good information on this.
  • JarredWalton - Friday, August 30, 2013 - link

    I honestly don't know if the limit is BIOS or Intel, but I suspect it might be BIOS. Usually, Intel lets you do +4 bins, and you can set SC, DC, TC, QC to the same multiplier (basically, what I could do with the 4900MQ). But perhaps Intel locked down the 4700MQ for precisely the reason that it would be nearly the same as a 4900MQ if you could set everything to 3.8GHz. Thermally, the 4700MQ didn't have any issues overclocked, but the 4900MQ behaved oddly; I think I need to tweak the OC settings to get more out of it, and even then I think it will only be at best a 3-5% improvement over stock clocks.

    Finally, regarding Alienware, the 18 is hard for me to go for, as it's so huge -- it's in the same category as the Clevo P370SM. I'm just not sold on SLI for notebooks, as there are too many gotchas (heat, size, drivers, cost, etc.) I didn't realize the AW 17 didn't do anything more for the display; I was hoping to see IPS/AVHA/PLS in there, but I guess not? Maybe next time; anyway, Dustin has the full review in the works, but the high gamut TN panel in the Clevo's is getting somewhat out of date.

    4700 = +200
    4800 = +400
    4900 = +600
    4930 = unlocked

    4.2ghz on all cores is a +600mhz boost to the core ratio:

    4900 = 38/37/36/36 (4core/3core/2core/1core turbo max)
    4990 oc max = 44/43/42/42

    The biggest restriction on the 4900 and 4800 will be that tdp increases are locked to +10w to 57w so going beyond 3.9ghz wont mean much (setting anything higher than 57w may looks like it has set but the cpu power wont go beyond 57w).

    Also powernotebooks is niw selling a 4.1ghz oced 4939mx and 3.9ghz 4900mq in the msi barebone range. How many times do we have to tell you your machine was a bad sample?
  • kogunniyi - Friday, August 30, 2013 - link

    You're right, but MSI deserves some flack for sending Anandtech two bad samples.
  • DanNeely - Friday, August 30, 2013 - link

    They've gotten a good one; hopefully at part of one of their upcoming articles they'll publish updated thermals. Unless the issue was a, now fixed, design flaw/fan controller bug though 2 faulty laptops in a row suggests serious QA problems that would scare me away.
  • JarredWalton - Friday, August 30, 2013 - link

    Anyone that thinks the MSI was a "bad sample" at this point is fooling themselves. You can keep "telling us we had a bad sample", but that just isn't true. Dustin had one MSI notebook, and at full load it hit 96C on the CPU (unless you trigger the max fan tweak that turns it into a blow dryer). Then he sent that back, and NVIDIA sent me not one but two MSI GT70 notebooks for additional testing. Both of those hit 95C on the CPU under full load -- 10C hotter than the P157SM reviewed here. That said, the MSI notebooks I had from NVIDIA did not throttle -- they just ran hotter than I'd like. 95C is still less than the 100C max that Intel specifies, but how long will you be able to game on a notebook hitting such temperatures before things start going south?

    Could we replace the TIM to get reduced temperatures? Perhaps, but I just don't think that should be standard procedure, and it shouldn't be required in the first place. What's more, it still won't run as cool as the dual HSF Clevo designs, since it's cooling two power hungry chips with one fan.

    As for the overclocking statements above, the maximum clock on the 4900MQ at stock is 3.8GHz, and pushing that to 4.2GHz was not stable (wouldn't even boot into Windows). While 4.4GHz is an option in theory, in practice I don't see it happening on any but the best CPUs. Even 4.0GHz is behaving oddly, with performance often lower than stock settings. I'm going to try a scaled OC of 4.1/4.0/3.9/3.8 to see if I can get any better performance than my initial results though....
  • Meaker10 - Friday, August 30, 2013 - link

    The thing is to go beyond 3.9ghz you will start having to add voltage which will instantly slam you into the 57W TDP limit. It looks like you were already hitting into it anyway.

    This is an even more delicate operation than a mITX desktop after all but can be done if you are patient.

    But by your own admission if throttle was not occurring on the sager then temps would likely be in the same area and the dual fan has no advantage....
  • JarredWalton - Friday, August 30, 2013 - link

    Temperature and power draw are different, so the 57W TDP is the factor. The Sager can better dissipate that (keeping the CPU at <90 and usually <85, with the GPU <80), but Intel's preventing higher Turbo even at lower temperatures. The MSI isn't throttling, meaning, it's not dropping below the rated speed, but it's also not running at max Turbo either. There's a difference.
