Benchmark Setup
We’ve covered our current selection of benchmarks previously, but in order to keep the graphs a bit more manageable so we can just say “ASUS UX31A” in the charts instead of “ASUS UX31A-DB71 (i7-3517U, HD 4000, 4GB DDR3-1600, 256GB SSD, 50Wh, 13.3-inch 1080p IPS LCD”, we’ve put together this handy reference table of the laptops we’ll be using in this review in the following table. Since this is an Ultrabook review, we’re focusing on Ultrabooks along with a couple of smaller laptops. If you’d like to make your own comparisons, our full selection of laptops is available in Mobile Bench. Note also that all of the laptop names in the following table link to the appropriate review.
| Laptop Configuration Overview | ||||
| Laptop | CPU | Graphics | Storage | Battery |
| Acer TimelineU M3 | Intel i7-2637M | GT640M/HD3000 | 256GB SSD | 55Wh |
| AMD Trinity Prototype | AMD A10-4600M | HD7660G | 128GB SSD | 56Wh |
| ASUS Zenbook Prime UX21A | Intel i7-3517U | HD4000 | 256GB SSD | 35Wh |
| ASUS Zenbook Prime UX31A | Intel i7-3517U | HD4000 | 256GB SSD | 50Wh |
| ASUS Zenbook UX31E | Intel i7-2677M | HD3000 | 256GB SSD | 48Wh |
| Clevo W110ER | Intel i7-3720QM | GT650M/HD4000 | 750GB Hybrid | 62Wh |
| Dell XPS 13 | Intel i7-2637M | HD3000 | 256GB SSD | 47Wh |
| HP Envy 14 Spectre | Intel i7-3667U | HD4000 | 2x128GB SSDs | 56Wh |
| HP Folio 13 | Intel i5-2467M | HD3000 | 128GB SSD | 60Wh |
| Ivy Bridge Ultrabook Prototype | Intel i5-3427U | HD4000 | 240GB SSD | 47Wh |
First, you’ll notice that every system tested in the above charts uses an SSD for storage, with the exception of the Clevo W110ER. That particular laptop used a Seagate Momentus XT 750GB hybrid drive, mostly because we wanted to get a feel for how it compared to pure SSD storage. The short answer: it doesn’t. While best-case workloads might not look bad, in practice there’s a big difference between SSDs and hybrid solutions. 64GB of SSD caching might be enough to eliminate most of the difference, but at that point you could just run with a 64GB OS+Apps drive.
In the other areas, we have eight Ultrabooks—four Sandy Bridge models and four Ivy Bridge models—plus our reference AMD Trinity laptop and the aforementioned W110ER. While Trinity is a 35W TDP processor, the improved gaming potential is certainly worth a look, and in practice battery life isn’t all that different from ULV Ultrabooks—though the size is generally quite a bit thicker unless you opt for a low voltage A10-4655M (which we still haven’t been able to test). Looking at the sizes of the laptops, the UX21A and W110ER both sport 11.6” LCDs, although the W110ER chassis is substantially larger than the 13.3” Ultrabooks. The AMD Trinity and HP Envy 14 Spectre are 14”-screen laptops, the Acer M3 is our sole 15.6” representative, and the remaining five Ultrabooks sport 13.3” LCDs.
We’ll draw two major comparisons throughout this review by highlighting the numbers in the graphs. Besides the UX31A, we’ll look at how much ASUS has improved since the UX31E, and we’ll also see how the UX31A stacks up to the prototype IVB Ultrabook from Intel. We’ll also highlight the Trinity results in AMD red, just so they’re easy to spot, but it’s not a major focus of the review. And with that out of the way, let’s get to the benchmarks.

GM failed partially because of "planned obsolescence." Would SSDs not be put into the same category, regardless of how long they last in the end?Tortoise vs hare, in my opinion (as small and non-majority it may be). We are starting to see low-end SSDs coming with only three years or two years of warrenty (thanks for the ever-informative reveiws, guys!). This means that, whether or not they continue to work, they aren't expected to work after 2-3 years. This is definitely inside the range of the average consumer's purchasing cycle, which usually stretches to 4-5 years.
This type of thinking is much more in line with CPUs and RAM, which will be obsolete within 2-3 years and need to be replaced (Moore's Law). Hard drives really haven't changed all that much in 15-20 years, and, really, are similar to the old tape spool drives in how they operate (speaking of tape, it is still used for mass storage...because it is reliable and lasts forever*, although tear-jerkingly slow...).
Just throwing it out there that there is still a (shrinking) contingency that will put up with double the boot times to get better reliablity. Not trying to be a jerk, just offer a different opinion (AND STAY OFF MY LAWN!).
*Forever=your mileage may vary

Just because something is out of warranty doesn't mean it stops working. For the record, I've had five people I know come to me in the past six months with dead/dying hard drives as a problem. Three were on laptops, two were on desktops, and only one drive allowed me to recover data (after putting it in the deep freeze). The oldest drive was around five years, three were less than two years old, and all were out of warranty because they came with an OEM PC (1-year to 3-year warranty).I can't imagine SSDs are really any less reliable than HDDs, which in my experience aren't worth keeping after 3-4 years regardless. They get incredibly loud (bearing noise), fragmentation of files means massive performance degradation, and most consumer drives are now designed to last 3-4 years before all bets are off. In four years, I'm certainly not going to be sad to have to replace a $200 256GB SSD with a $200 1TB+ SSD that will likely run at even higher speeds.
Put another way: when was the last time you even thought about reusing a 3+ year old hard drive in a new PC build? Every time I help someone put together a new PC and they ask, "Can't I just use my old hard drive?" I respond with an emphatic "NO!" Then I explain that technically, yes, they can, but when $70 gets you a modern 1TB drive that will be more reliable and faster, do you really want to use your 4+ year old drive that might fail at any time? If they insist, I usually refer them to someone else, because I won't be responsible for putting together that sort of system and then having to provide support when things go south.
When have you needed to get the data off an old IDE drive where the data wasn't already backed up somewhere else? Even old SATA drives are now retired to the scrap heap (after copying data off, if necessary/possible). If people are keeping drives for 10 years and not backing things up, they're going to lose that data at some point.
SSDs aren't necessarily more reliable in any of these areas, but I've had enough issues with HDDs over the years that I wouldn't trust them as far as I can throw them. HDDs to sail pretty far on a good toss, though.... ;-)

Three reasons ultrabooks have not caught on.1. Price
2. Price
3. Price
The mainstream public will not pay the price for an ultrabook, when they see a laptop for $350 sitting next to it. I know the advantages of an ultrabook, but the general citizen does not care enought to pay 3x or 4x the price. It is still somewhat a niche product.

I've read some articles(not on this web) how is Intel going to push prices for Ultrabooks dows to 700-800 level while this one almost doubles it.U'll get nice screen but NoN upgradeable RAM(4GB max) NoN upgradeable SSD...would not pay more then $700 for that, it's just now worth it
I only hope ultrathins based on Trinity will bring some nice alternative because copying Apple designs and asking same money for it is just a bad JOKE

It's 2012. Seriously. Why can no one make a frigg'n touchpad that just works?Paedric - Tuesday, August 28, 2012 - link
Sadly, it's probably because of patents.KPOM - Tuesday, August 28, 2012 - link
The ASUS sounds like the top Ultrabook right now. I wonder why they didn't make an 8GB option, though, since it's available in the MacBook Air, and for the most part ASUS has taken its design cues directly from Apple with this particular line. The 1080 IPS screen is a nice touch, and it's good to see that battery life is still pretty good.What does it take to get a Silver or Gold from AnandTech? The top ultraportables (ASUS UX31A and MacBook Air) get Bronze. I think Silver would be well warranted for both. The ASUS has the best screen in the business, and the Air has 8GB RAM and 512GB SSD options.

8GB and a touchpad that doesn't come with any caveats would have been Gold. Each of those items dropped it a notch in my book. The pricing is also somewhat of a factor, as a lot of people are going to shy away from $1400, though the $1030 model DB51 is at least a bit more reasonable.Aikouka - Tuesday, August 28, 2012 - link
You touched on it in your review, but I'd highly recommend that you try installing the Elantech drivers. I have a UX31A-DB51 (128GB SSD variant), and I've been using the Elantech drivers with no problems. Here are my qualms with it though...* The touchpad is too big and it's not recessed. I have the same problems with my Transformer TF300, but the fact that the touchpad is rather large and not recessed means that it's very easy to hit it with your palm while typing. I don't have this problem on my old Dell XPS M1530, because the touchpad isn't that large and it's recessed. Although, it doesn't seem to ever register my palm taps near the top as clicks, which is a good thing. I typed up a few forum posts on it last night, and the worst that I did was move around the cursor a little bit.
* No middle mouse button. I've gotten pretty used to using the left mouse button + right mouse button to act as the middle mouse button. I mostly use it for doing things like closing browser tabs (middle clicking on the tab itself closes it). However, this doesn't work with the UX31, which might be an issue with the Elantech drivers?
* Only has USB 3. This is mostly an issue if you're neurotic like me and refuse to use the default Windows install. Since Windows 7 does not support USB 3 by default, I had to jump through a few hoops just to reinstall Windows and put my drivers on the laptop. However, a fellow forum goer said that turning the USB legacy option to "always on" (instead of "smart") would allow the Ethernet adapter to work. This at least will allow you to download the drivers.

Can you direct me to a link where I can get the Elantech drivers? I commented on this in the review, and I can't find any non-ASUS drivers for Elantech out there. As for middle-click, I put in a request with ASUS to add that functionality.
