Introducing the Mythlogic Callisto 1512 (Clevo W550EU)

While boutiques and SI's have traditionally had a pretty decent stronghold where the consumer desktop was concerned, the notebook market has been a lot more unstable. Vendors like AVADirect, CyberPowerPC, iBuyPower, Puget Systems, and today, Mythlogic, are all essentially at the mercy of primary ODMs like Clevo, Compal, and MSI to give them whitebooks they can custom build for their customers. With ultrabooks gaining traction, that puts serious pressure on these vendors, as conventional 13.3" and under ultrabooks are much harder to offer in a customizable shell. Intel's 20mm or less thickness spec means socketed CPUs aren't an option, and what you're really left with, if you're lucky, is the ability to customize wireless connectivity, memory, and storage. Slim pickings.

The expanded ultrabook definition gives boutiques a little more breathing room, though, and that's how we end up with a review unit like Mythlogic's Callisto 1512, based on Clevo's W550EU. Essentially what we're looking at is a much thinner 15.6" notebook that still offers the boutique the ability to customize the processor, and we get a 35W or even 45W CPU instead of the reduced voltage and wattage 17W Ivy Bridge chips in most ultrabooks from bigger vendors. And while these Clevo/Compal/MSI notebooks may sometimes not be as well built as their retail counterparts, they tend to offer the superior display options that the bigger vendors often won't.

Unfortunately, the exact configuration we were shipped for review can't be built on the Mythlogic site yet. The Intel Core i5-3340M is a refresh of Ivy Bridge not currently listed; you can either drop 100MHz and go for the i5-3320M, or gain 100MHz and go for the i5-3360M. Either way is probably fine; the incremental CPU options are appreciated but not strictly necessary. It's worth pointing out just how much of a performance jump you get going to standard voltage, though: top-end ULV Ivy Bridge runs ~2GHz before turbo, but the i5-3340M in our review unit starts at 2.7GHz and goes up from there. That the W550EU can support quad core CPUs suggests there's a good amount of thermal headroom here, too, so the i5-3340M will be much more liable to spend a lot of time at high turbo speeds.

Paired with it is 8GB of DDR3-1600 courtesy of Patriot, and handling storage duties is a 256GB Samsung 840 Pro SSD, plenty for most users. Should that somehow not be adequate, the W550EU also features an mSATA slot, so if you need more storage you can pop a 256GB SSD into the mSATA slot and use the 2.5" drive bay for a 1TB mechanical hard disk. I'm disappointed the only optical drive option available is a standard DVD writer, though; an optional blu-ray drive would've been appreciated.

Of course the major selling point here is the 1080p matte IPS display. While Clevo offers a version of the W550EU that uses a bog standard (and probably hideous) 1366x768 TN panel, Mythlogic wisely doesn't even offer it on their site.

Eagle-eyed readers will note that this review unit features Intel's 802.11ac adapter. While I didn't have enough time to test it with a proper wireless-ac router, I will say that in its present state it's...definitely functional, but I found the range on it is somewhat lacking. About fifteen feet from my router and through two walls, signal strength was actually on the low side. On casual inspection, performance appeared strong and stable, but wireless networking is admittedly not my jurisdiction.

    Yea, I thought the same. Currently, the ASUS Zenbook ( is the only system I'm aware of that's really light and has a discrete GPU.

    I've been using a Maingear branded Clevo W150hrm). Looks exactly like the one in the image. It's fast and the display is great. It's not super durable (a battery tab broke and something else broke loose inside the case that I haven't gotten around to fishing out yet) and there's no latch. My biggest gripe is that I still screw up typing on this thing all the time. Right shift, right control, and the arrows are all way too easy to mix up and make development typing a real trial. I miss my Dell keyboard so much. Also it doesn't include the lucidlogix software to let the embedded and nvidia gpus work together. At least it uses regular old phillips head screws.

    Doesn't the ASUS UX51 cover the bases as far as good display, good graphics, lightweight, etc.? Plus, they often offer two-year comprehensive warranties on a lot of their laptops, so there's that. I know there's a bit of a price difference, and there may be some other things as well, but I'd look towards that direction rather than a "custom-built" ultrabook if I was still in the market.

    I don't understand why the sony S15 isn't mentioned in the article. In my county, the S15 is cheaper than the equivalently specced clevo. (unless you opt for a quadcore option, because the quadcore is only available in the GT 640m 2GB model, which is an €170 upgrade).

    What do you get for that? A vasly superior keyboard and touchpad. Much longer battery life, superior cooling, 300gr lower weight, and probably better build quality as well.

    Clevo once again managed to create a system that is just surpassed by the competition in every possible way.

    The thing with ultrabooks is, if I'm spending over 1K on a laptop I expect a dedicated GPU. I should be able to run, at a minimum, every modern game at 1600x900 with smooth frame rates. I don't expect the detail settings to be all the way up, but I don't want to run 720p. MAYBE this will become reality with haswell and the integrated GPU RAM; but honestly I'd rather have an Nvidia chip in there for MANY more reasons than just gaming performance.

    I LOVE the Clevo design, I'm entirely happy with it the way it is. Except that keyboard. WHY didn't they use the same one they've been using on their newer 15.6" GTX660M laptops? That keyboard layout is great! This one is damn near useless because of that stupid offput 0 key. Hey laptop people, arrow keys are almost entirely useless, YOU CAN MAKE THEM SMALLER!
