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.

Thanks for the prompt response!ph2000 - Wednesday, August 29, 2012 - link
isn't the headphone jack is a combo for headphone and microphoneit has 4 pins, same as phone headset

All I know is I plugged in a microphone and while the Realtek control panel popped up a "device connected" message, it didn't allow me to configure the mic -- it set it up as headphones.ph2000 - Wednesday, August 29, 2012 - link
it because normal headphone and mic jack has the same pin arrangementuse an adapter/splitter (TRRS to TRS) to use normal microphone
TRRS = 4 pin
TRS = 2 / 3 pin
something like this

Why on earth would ASUS include a mini-VGA port with a VGA adapter instead of a mini DisplayPort with a VGA adapter? I mean I understand an analog output can still be useful from a lowest common denominator standpoint, but if you need a dongle to use it anyway, why not just go mini-DP?I can only assume it has something to do with the Ivy Bridge FDI requiring at least two of the three display outputs to share a pixel clock. Still odd though.

Will we see a mini-review discussing more in-depth differences between the UX31A and the UX32VD?The upgrade-ability of the UX32VD seems like it would be almost every bit as good as the UX31A in most respects. It addresses the lack of availability of an 8GB upgrade since it has one slot for RAM available for upgrades, and it has a standard SATA 2.5" HDD. It could be argued that throwing an SSD in the UX32VD makes it the best ultrabook money can buy. It's a bit more expensive than the UX31A if you do that, though. But still.

Anand has the UX32VD and is working on that review; I don't know when he'll be finished, though. My biggest issue with the UX32VD is that most of the models lose the 1080p display and the HDD + SSD hybrid solution basically stinks compared to pure SSD. (That latter bit isn't just an ASUS problem, of course.)ka_ - Tuesday, August 28, 2012 - link
That is the laptop I am most interested in! The main reason I will select UX32VD with IPS over UX31 is bad experience "mini" ports - the UX32VD got full size HDMI port. Also the UX32VD have one 2GB ram chip that can be changed with an 8GB giving a total 10GB ram. About pure SSD vs hybrid, I must say I favor hybrid still, though I could just as well bring an external USB 3.0 disk when space is needed. I would have liked to see the UX32VD without a dedicated graphics card - I have an Asus UL30VT currently and I never use the extra dedicated graphics card anyway. It could be interesting to know if the dedicated graphics card can be removed from the unit to save more weight or maybe even replaced with another SSD disk?Conficio - Tuesday, August 28, 2012 - link
Exactly. I'm looking time and again at the UX32? and the options that are affordable and shed the unnecessary GPU, those have a crappy display.Soldered RAM and proprietary SSD are only things for people with too much money. to be honest at this day and age I don't want a built in SSD in the first place. I'd rather buy it after market to have choice over controller and warranty.
I'd even prefer a 14" or 15" version with an mSATA for the SSD and a 2.5" drive bay for the HDD and a beefy battery to boot.

Oh, no, I agree. I'm more referring to the versions with that excellent 1080p screen.And if I'm spending that much on a laptop, I don't think I'd have a problem finding a 128gb or 256gb SSD to put in it to replace that rather disappointing hybrid combo. That makes it a $1600-1700 laptop, though ($1500 for the laptop and $100-200 for the SSD).
But still. Points for being able to upgrade an ultrabook that isn't too much bigger than the one you reviewed with standard parts.
The only reason I push for a dedicated GPU is because when I find myself wanting it, it's REALLY nice to have. Most of the time, it's not needed. Those edge cases where I actually want one (playing an MMO on the go, etc.) make it worth it though, considering I upgrade laptops about once every 3-4 years at this point.
Then again, this whole argument about a dedicated GPU could be moot with Haswell, which should be awesome from a GPU standpoint for no other reason than the eDRAM, much less the 40% more compute resouces (I think that's right anyway).
