GPU Performance: A Step Back
There's no room for a discrete GPU in either the 11 or 13-inch MacBook Air, at least based on their current motherboard designs. Instead you're stuck with Intel's HD 3000 graphics on the dual-core Sandy Bridge die. For general use, Intel's HD 3000 is fast enough. As I mentioned earlier, even connected to a 27-inch display you get reasonable performance out of Sandy Bridge's GPU.
Where the HD 3000 falls short is in gaming performance, particularly at the native panel resolution of the 13-inch MacBook Air:
At 1280 x 720, the HD 3000 is fast enough for today's Mac games:
The HD 3000 is also a bit slower than the GeForce 320M used in last year's MacBook Air, at least in games that aren't largely CPU bound (basically anything but Starcraft 2):
While gaming is possible on both Air models, it's far from ideal. Apple definitely fixed the CPU performance with the new Air, but through no fault of its own failed to address GPU performance. Intel seems committed to taking GPU performance seriously, let's hope we actually see that in the coming years.

In your "2011 MacBook Air Lineup" table the "Cores/Threads" and "Base Clock Speed" categories are messed up.Excellent review btw

Thanks for the review. I am very interested in the 13" MBA as it's the only ultraportable I can find that has what I consider to be the ideal resolution for a laptop display with good performance and battery life (the thinkpad x301 is a close second but there's too much of a performance sacrifce there although I prefer the ports and features on the x301).I need a windows machine... I'm just trying to find out if the MBA is a good windows only machine. I hear conflicting reports on this... I'm sure you guys are busy but if you find the time I'd love to hear your thoughts on using a MBA as windows only.

Hi Anand, you have a small typo on the specifications table:Base Clock Speed Intel HD 3000

"Apple has sold a USB 10/100 Ethernet dongle in the past for MacBook Air owners, but these days you can get better performance over good WiFi than you can from 100Mbps Ethernet"
I would like to see some testing that substantiates this claim.
In my experience traditional 802.11a/b/g/n can't sustain speeds anywhere near what a 100Mbit wired connection can do. Not to mention that if you are running WPA or any other encryption you take a substantial bandwidth hit.

With a good router and WiFi card, and if you're in relatively close proximity to the router, 802.11n can definitely outperform 100Mbit Ethernet. If you're on the other side of the house, it will be slower, but then you'd have to run a 150 foot Ethernet cable. Now, Gigabit Ethernet is in a league of its own compared to WiFi, but we already knew that.Penti - Wednesday, August 10, 2011 - link
Just attach a 10GbE adapter to it then :) Thunderbolt does suppport this kind of expansion.Uritziel - Thursday, July 28, 2011 - link
It's not really necessary to substantiate a claim that an up-to-450Mbps standard "can get better performance" over a 100Mbps standard :\Silenus - Thursday, July 28, 2011 - link
Did you read the the rest of the review? This WAS tested. See the SSD and WiFi performance section:http://www.anandtech.com/show/4528/the-2011-macboo...
Both the 11 and 13 topped 116Mb transfers. 15 Macbook Pro and recent iMac did even better.

1) That's peak speed.2) That's probably for only one WiFi user with a good zero interference connection to the AP. Add another WiFi user (or ten ;) ) and the speed will drop.
Some (not all) APs also slow down everyone if a WiFi B/G user connects.

You're also not going to hit line speed on 100 Mbps networks without an optimal set of conditions. For everyday use (even with multiple users, etc), 802.11n is good enough and far easier to install a new network than 100 Mbps wired Ethernet.If you're doing a lot of the large file transfers or movie streaming, consider installing a Gigabit network though.
