Mythlogic Callisto 1512 (Clevo W550EU) Ultrabook Review
by Dustin Sklavos on May 24, 2013 12:01 AM ESTDisplay Quality
One of the things boutique releases of ODM notebooks typically can offer over the notebooks on retail shelves is a superior display panel. As I mentioned earlier, Mythlogic doesn't even offer the W550EU with a garden variety TN panel; the only option is the 15.6" 1080p IPS, and that's something I actually appreciate. That it's a matte panel may be an even bigger selling point for some, though it isn't touch enabled as increasing numbers of modern displays are.
While the display is comparatively attractive and still ranks well above a garden variety TN panel (as evidenced by the HP Folio's dismal performance), color gamut is unusually poor for an IPS display. This isn't something immediately evident in regular use and would probably only be noticed with the kind of testing we do, but it is nonetheless worth mentioning. Contrast and brightness are excellent, however, and any way you slice it, it's a massive improvement on a low-resolution TN panel.
Battery Life
Unfortunately, these ODM units are oftentimes poor performers when it comes to battery life. For one reason or another they're just not particularly well optimized to run off of the mains, and the result is reduced mobility overall. The Clevo W550EU sadly doesn't buck this trend.
Running time off of the mains, even normalized, is fairly poor. It takes a quad core CPU and dedicated graphics (albeit running on Optimus) to put in a worse showing, and even then you're looking at essentially another ODM machine. The 62Wh battery is basically essential to get useful battery life out of the W550EU; Clevo offers a smaller one but that seems to be another component Mythlogic opted to just sweep under the rug in favor of the superior option.
Heat and Noise
The one thing these larger ultrabooks tend to do better than their smaller counterparts is cooling: more space for cooling often means lower temperatures and/or lower noise. Even with the 35W CPU, the Clevo W550EU gets most of this right, but I'd caution against configuring this notebook with a quad core CPU.
Even under sustained load, the W550EU is relatively quiet, but the CPU does get fairly hot and the left side of the notebook (next to the vent) actually gets pretty warm. If you routinely find yourself resting a fingertip or two on the bezel surrounding the keyboard, you're going to feel it. So while Mythlogic does offer quad core options with the Callisto 1512, the only one I would recommend is the 35W i7-3612QM.

At least we have you patrolling... good work.kallogan - Friday, May 24, 2013 - link
This laptop misses its point since it consumes too much at idle, more than discrete gpu based laptop. While i love Clevo cause it allows easy upgrade of all components including cpusetc...they can do a lot better power consumption wise. It's they're first ultrabook like lap so they should improve on the next Haswell series.CadentOrange - Friday, May 24, 2013 - link
Can you investigate into why it's consuming so much power? Is the CPU not throttling down when idle? Is the IPS display at fault? The normalized results show that it's consuming nearly twice the power of the other ultrabooks.It is truly baffling that a laptop with standard components and an integrated graphics chip will consume so much power!

Clearly you've never used the current model XPS 15. It's the worst notebook I've ever owned, ask Jarred Walton for details.Wilko1337 - Friday, May 24, 2013 - link
PCSpecialist also sells custom laptops with the Clevo W550EU frame (marketed as the 15.6" UltraNote).Quite a few users have had problems with the display's backlight bleed show here: https://www.pcspecialist.co.uk/forums/showthread.p...
Regard this and the review FWIW

That's 3 users. And the bleed in the pictures he provides doesn't seem very substantial. If you watch a lot of dark movies, it may be a problem, but that kind of bleed will usually not be noticed in every day windows work and game.CadentOrange - Friday, May 24, 2013 - link
That bleed looks bad, and if it's "within parameters" and not getting fixed then I think it's something that should be flagged up for prospective buyers.Conficio - Friday, May 24, 2013 - link

When I first saw this, I said cool - an ultrabook with a discrete GPU. But alas, no discrete GPU and it weighs freaking 5 pounds. This sir or madam is not an ultrabook.bitterman0 - Friday, May 24, 2013 - link
Exactly. Ultrabooks are 3lbs, maybe 3.5lbs on the outside. For crying out loud, my 2006 ThinkPad T41 is 5lbs!
