The Test
To keep the charts clean and simple I omitted a lot of the config details of each of the notebooks. For your reference, here's the configuration of each of the notebooks in our tests:
Dell Inspiron 11z (SU4100 + GMA4500 + HDD + 56Wh)
Performance
As I mentioned earlier in this review/preview, the deal ASUS worked out with Intel prevents us for discussing clock speeds or specifications of the ULV Ivy Bridge silicon in the Zenbook Prime. Obviously the silicon is going to fit within the same 17W TDP as its predecessor so don't expect huge differences in clock speeds.
If you take into account Quick Sync and its SSD, the Zenbook Prime is an extremely quick solution. Looking at the breakdown of PCMark scores you get a much more realistic look at where the ULV IVB fits into things.
In some areas the Sandisk U100 holds the Zenbook prime back, here it's actually slower than its predecessor. Despite all of its issues throughout most of last year, SandForce was always fast.
I threw in a PCMark Vantage graph as we have a lot of older data in that benchmark that can help put things in perspective:
It's amazing the sort of performance gains we're able to show over the older Core 2 based ultra portables like the Dell Inspiron 11z and Adamo 13. Again we see a slight performance deficit versus the SandForce based UX21E.

2 years ago when Sony first released the VAIO Z with the 1920x1080 display, they said that because the grid of pixels was more dense, it needed 25% more backlight power than the 1600x900 version in order to have the same level of brightness.Maybe the same thing happens with this new IPS display, and that may be one of the reasons why the battery life is not better than the previous generation.

I've yet to see what's so ultra about this. The performance is not their, the gpu sucks and they are not Apple to be selling things with not much use. Good luck with this.CaioRearte - Tuesday, May 22, 2012 - link
Sorry Intel, but it seems AMD won the slim-notebook round. Intel can't catch up on video performance at this wattage, and tons of processing power aren't exactly what a laptop owner is looking for. Since AMD has been turning towards diverse computing methods for a while, and actively dedicating more to the graphics than to raw power, their products will be more balanced and enticing in the long run.Anyway, the UX32 with the dedicated 620M looks like a good contender, when are you getting your hands on it? :)

I have the previous version of this which I bought a few months ago.... it didn't have a backlit keyboard or anything else I expected it to have, with the keyboard being annoying and all, but the laptop functions well. I was just curious if the first models are tradeable for a newer model?That extra USB port would be very useful for me right now.

Well, you certainly won't be able to trade in the older model, but you could easily sell it on Ebay when the new one comes out. If you are talking about replacing your keyboard for the backlit keyboard on the new one, I wouldn't count on it. It sounds like it has been substantially redesigned.On the plus side, you'll have enjoyed your new laptop for have a year by the time the new model comes out. There will always be a better model coming out in 6 months. Enjoy what you've got.

I think the improvement in battery life can be attributed to the following:-USB 3.0 controller moving from a dedicated chip to a integrated one in the HM7x PCH
-Improved software/hardware build quality. Also maybe the Sandisk SSD offers bettery battery life?
-DDR3L memory? Ivy Bridge allows DDR3L support, and I've also read that the new Zenbook uses one

I know it's a copy of the Macbook Air, but 4GB isn't enough for people running VMs. And you know Apple is going to increase their memory limit with the next release ;-)Love the screen though...about time they started putting high density screens in these things...

Confused on the configuration versus the price on UX32.As far as I can see, the $799 vs. $ 999 device differs only in additional HDD. I would have made sense if its an SSD difference
Am I missing something here?
