Performance

Now for the good parts. We’re actually pretty familiar with the computing platform behind the Edge. The ultra-low voltage IVB parts are commonly found in ultrabooks and are some of the AT mobile team’s favorite mobile processors right now. I’m not the only one, Dustin just rhapsodized about the ULV Core i5s in his review of the updated Dell XPS 13 last week. The usable performance and reasonable power draw on offer are just that fantastic, and these CPUs really represent the sweet spot of the market right now. I’m not sure that the additional CPU headroom of the i7s is really necessary or worth the additional cost; the 100-200MHz clock speed bumps are pretty incremental. The only really compelling thing about the i7 SKUs is their ability to hit 3.0-3.1GHz on Turbo, a solid 400MHz higher than the corresponding i5 parts.

The other thing is that I’m seeing a lot of cases where there will be two SKUs on offer – one with an i5, 4GB RAM, and a 64GB/128GB SSD, and then a high end one that offers spec bumps across the board – i7, 8GB, and 128GB/256GB. We’re moving away from the early 2000s Dell/HP/Gateway-era of pick your component computing, so the decision between i5 and i7 chips might actually be hinge on the rest of the package, as is the case with the Edge.

Anyways, that’s diverging a bit. We’re very familiar with both of the CPUs used by the Edge from various ultrabooks; in particular, the i5-3317U is the heart of my trusty ASUS Zenbook Prime and I just recently looked at the i7-3517U in my review of the Vizio CT15. The i7-3517U has a base clock speed of 1.9GHz and a max turbo of 3.0GHz, along with HD 4000 onboard graphics (350MHz base clock, 1.15GHz max). It performs roughly where we’d expect, and I’d also like to highlight the relative lack of differences between the i5 and i7 ULV SKUs here.

Graphics Performance

Nvidia’s mobile GPU heirarchy can get very, very convoluted, particularly at the low end, with a mix of new, old, and gap-bridging parts all under the same name. As such, there are many variants of GT 640M and GT 640M LE, with a mix of SKUs spanning the 28nm Kepler, 40nm Fermi, and 28nm die-shrunken Fermi cores. An interesting and related side-note: a few days ago, Anand asked the mobile team if we had seen any Kepler-based GT 630M notebooks. It took a bit of searching, but eventually it was determined that none of the GT 630M SKUs are actually Kepler based, only 28nm and 40nm variants of the Fermi core. When the lineups are so jumbled that even we can’t keep track of them, there’s something wrong. Why are some GT 640Ms so slow, while others are nearly equal to the DDR3 GT 650M? Why are there still 40nm GeForce 600M parts? I wish Nvidia could simplify and streamline their mobile GPU lineup, it’d make our lives easier as well as being a lot more transparent for consumers.

The GT 640M LE in the Edge is thankfully a Kepler part, so a 28nm GK107 core with 384 cores, 16 ROPs, and 32 TMUs, just like all Keplers from the GTX 660M on down. This is the absolute bottom of the range, so it has the slowest memory configuration (900MHz DDR3) and a 500MHz core clock, with boost up to 570MHz. The next big hardware jump comes with GDDR5 VRAM in the GT 650M, and a combination of clock speeds and GPU boost make up the differences between SKUs.

The 1366x768 panel comes into play here – Kepler, even at 500MHz, is more than capable of pushing 768p displays at high settings in modern games. High quality textures really start to tax the slower memory in the low-end Kepler cards as you increase resolution, so even with higher clock speeds, 1080p gaming will be non-ideal at best and downright bad at worst. Don’t expect much to be playable, as even the DDR3 variant of the GT 650M basically failed the 1080p portion of our gaming tests. The GDDR5 GT 650M and the GTX 660M (which comes in GDDR5 form only) do better here, but there’s a pretty substantial gap between those two chips and the rest of the GK107 mobile parts at 1080p.

We haven’t yet finalized our 2013 Gaming test suite, so I just ran our 2012 test suite. I did almost all of my testing on the road, sans access to 1080p displays, so I only have 1366x768 gaming results (that’s our value gaming suite, which runs medium detail settings at 768p). I also ran at high detail settings, to see what kind of differences there would be. Once our new suite is finalized, I’ll update with results at 1600x900 and 1080p.

The Edge does pretty well, honestly – Kepler is a great mobile GPU, even clocked so low. At high settings, almost everything was playable, except for Battlefield 3 and Civ 5. I think Civ 5 is CPU limited on the Edge, while BF3 is one of the more strenuous games we test, so both of those were expected. Lower the settings to medium, and pretty much everything is playable.

The higher clock speeds of the GT 650M (DDR3) in the Clevo W110ER really make themselves felt, with substantially better gaming performance than the Edge throughout our benchmark suite. For a comparison with Surface Pro and the other IVB tablets, look at the ASUS Zenbook Primes - the UX31A with the 1.15GHz HD 4000 (i7-3517U) and the UX21A with the same HD 4000 clocked at 1.05GHz (i5-3317U). There's a small performance delta between the two due to the maximum frequency difference, but either way, HD 4000 seriously struggles to be playable in most of our benchmarks unless you lower either the resolution or detail settings. Again, Kepler at 500MHz is still a pretty capable card at 1366x768, so concern over frame rates is probably a moot one unless you’re gaming on an external display.

    Because Razer operates on large profit margins, and judging by the Blade and this thing, I'm pretty sure they don't really have any interest in putting out cheap "me-too" platforms. They're more interested in pushing innovative platforms and don't need or expect to move large volumes of the product.

    The Vita isn't a full PC with a real OS and Ultrabook level hardware with a game library anywhere near as big as Windows. Stupid comparison.

    Lolz, this is designed fist as a portable gaming device even though it makes every compromise you can. its price its stupid high, and it looks plain goofy. This thing is stupid and has no place in the market. It sits right up there with the N-gage in the history of dumb gaming devices.

    How can you not include IVB integrated results in the games charts? What is wrong with you? That is the ONLY important test that needs to be done to the Edge - is it worth the cost and added bulk over integrated or is it not...

    Also, saying Civ V is not playable is ridiculous. You did something wrong in the testing. It was playable on my ancient HP tm2 tablet, and that is worse than even the IVB integrated GPU. With the Edge it should be a ton better.

    I really do love the idea of this but it is obvious to me I'll have to wait a year of two for this category to mature. The next few years are going to be interesting.

    Once again their first attempt is not viable. At 1000 dollars I'd like to see a higher resolution screen, 1600x900 at least. I realize the gpu can't take it, but you can run games at 720p and you'll be fine. Resolution comes down to screen real estate. I need more than 768 vertical pixels. Especially at $1000!!! Furthermore I agree a 64GB SSD is almost useless. 128 should be the entry point with a 256 and maybe a 380 option. I know they can get 256GB SSD's for 150, probably less if they buy in bulk.

    The thickness of the screen bezel makes me feel like it belongs in the late 90's/early 2000's. Expand the screen .4 to .6 inches and keep the same chassis with a smaller bezel.

    I see no value from the i7 "upgrade" and don't want to be forced into it just to get a reasonably sized SSD.

    On the controller, maybe try moving ab xy to the back, so they line up with you ring and middle fingers? Not sure how well this would work as I've never used anything like it.

    Can they get any more stupid? They just trashed any hope of any future for this brand name. This is way way waaaaay too much money to pay for something that gives you such a small boost compared to a bargain bin AMD A10 notebook. They should have just waited for Richland and made a deal with AMD. They could have gotten about the same gaming performance, with 50% better battery life and $400+ cut from the price tag. They could have brought us something decent without the outrageous price that is going to make most people laugh and never look at this brand again. People commenting on facebook and twitter are just morons. It is easy for people to say they want all these things from a product, but it doesnt mean they are actually going to buy what they claim they want.

    They should use an AMD Jaguar for this. Only an AMD APU will provide the kind of low power consumption and great GPU performance stuffed into a 15w power envelope. Jaguar's GPU destroys the GT640.

    So basically this is a tablet thicker than an Ultrabook, with less i/o ports than an Ultrabook, and overpriced gamepad that make it wider than a 17" gamining laptop, all for the pleasure of playing at 1368 resolution?
    No thanks I'll keep my Alienware notebook. For gimmicky games at low resolution I have a phone.
