Mythlogic Pollux 1613 / Clevo P157SM Reviewby Jarred Walton on August 30, 2013 12:00 AM EST
A couple months back we had the chance to review MSI’s GT70 Dragon notebook, a high-end gaming system sporting the brand spanking new Haswell Core i7-4700MQ with a just as new GeForce GTX 780M graphics chip. What we found was that performance didn’t impress us quite as much as we were expecting. Mythlogic wanted to show us “GTX 780M done right”, more or less, so they shipped their Pollux 1613 (Clevo P157SM) system for review sporting similar hardware to the GT70 Dragon…and performance once again wasn’t quite what we were expecting in games. It’s not that either system was slow, but we simply expected to see more of a difference.
After some emails back and forth with NVIDIA and Mythlogic, we ended up with a second CPU for testing: the Core i7-4900MQ (not to mention some overclocking of both the original 4700MQ and the 4900MQ processors). NVIDIA has also sent two new MSI GT70 Dragon notebooks for testing, one configured the same as the original review (and it no longer hits 95C or higher temperatures during testing) and one with i7-4930MX. But we’re getting ahead of ourselves. We’ll look at the CPU scaling performance of GTX 780M in a future article, but for now let’s talk about the Mythlogic Pollux 1613, a customized build using a Clevo P157SM chassis. Here’s the specific configuration we’re testing:

Most of the items are pretty much what you’d expect from a high-end notebook, with a quad-core i7 CPU and GTX 780M providing the raw horsepower for any games or other computationally intensive tasks. As mentioned above, we tested with both the i7-4700MQ and the i7-4900MQ, including overclocking via Mythlogic’s customized BIOS. We also requested a single large SSD for our review unit and Mythlogic obliged and equipped the notebook with a 512GB Samsung PM841 mSATA SSD. The choice of SSD was less about performance than it was about convenience; I have found that 240/256GB SSDs just aren’t quite large enough to hold everything I want. Bumping up to the 512GB class fixes this shortcoming, and there’s still plenty of spare area available for future games and applications—and you can always add an additional HDD if needed for mass storage of data files. If I were buying a high-end laptop right now, I’d definitely splurge and get a 512GB class SSD.
Going through the rest of the list, most of the items are well-known quantities by now. The AUO B156HW01 v4 LCD is a TN panel, but it’s one of the best 15.6” TN panel out there, with a wide color gamut and good (post-calibration) accuracy, as well as viewing angles that don’t immediately wash out in off-angle viewing. RAM in our unit is “only” 8GB of low-voltage memory, but you can equip the P157SM with up to 4x8GB RAM if you need more, and Mythlogic’s pricing for RAM upgrades is pretty reasonable. (The 32GB setup mentions that it requires the use of Windows 7 Pro/Ultimate according to Mythlogic’s configurator; Windows 8 64-bit supports 128GB and the Pro version supports 512GB, so this is likely a note for Win7 users.)
The connectivity and I/O options cover just about everything you could want. There are three USB 3.0 ports, including an eSATA combo port. A single USB 2.0 port is also present for legacy/compatibility reasons (I’ve noticed that trying to install Win7/Win8 from a USB 3.0 port often creates problems). Clevo even includes a FireWire 1394b port for those that need it, and on the display side there are three digital connections: one full-size HDMI, one full-size DisplayPort, and one mini-DisplayPort. VGA and DVI users will need an adapter, but given where we’re headed I think going with two DP connections is the best choice for most users. For wireless, we were very pleased to discover that Mythlogic equipped their notebook with an Intel Wireless-AC 7260 adapter; the configurator has now moved on the Advanced-AC 7260, which adds Bluetooth 4.0 support. Regardless, the ability to transfer data over WiFi at up to ~45MBps is something I’ve been longing for; range of 802.11ac won’t be as good as 2.4GHz networking, but since you get 2.4GHz and 5GHz support it’s not really a concern.
As far as the spec sheet goes, there really aren’t any problem areas to discuss. You can custom configure pretty much whatever your heart desires, within reason. The P157SM chassis supports two mSATA drives, two 2.5” SSD/HDD drives, and if you want to forego the optical drive a caddy allows the use of a third 2.5” SSD/HDD. There’s a very similar notebook that’s also available, the Clevo P150SM/Mythlogic Pollux 1613-Black; the major difference is that it only supports a single 2.5” drive (with a second via the optical drive bay/caddy). It weighs a bit less than the P157SM and has a slightly different design on the hinges and multimedia panel above the keyboard, and no backlit trackpad, with a price that’s around $20 less. (It’s basically the last generation Clevo chassis but with an updated chipset/motherboard and other components.)

Khenglish - Friday, August 30, 2013 - linkIt 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.
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.
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.
JarredWalton - Friday, August 30, 2013 - linkYeah, 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.
Khenglish - Friday, August 30, 2013 - linkDidn'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.
JarredWalton - Friday, August 30, 2013 - linkThe 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.
Moooza - Friday, August 30, 2013 - linkI'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.
JarredWalton - Friday, August 30, 2013 - linkIf 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.
cmikeh2 - Friday, August 30, 2013 - linkAll units of the P150SM I've found only had 120W power adapters. Do you see that as an issue?
DanNeely - Friday, August 30, 2013 - linkXoticPC defaults to a 180W with the P150SM
cmikeh2 - Friday, August 30, 2013 - linkMy bad I totally blanked there.. You're right. I was conflating P150SM with P151SM1 for some reason.
Khenglish - Friday, August 30, 2013 - link180W 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.
