8870m, so you're comparing a mobile discrete GPU to the Iris Pro which is an integrated GPU.
Let's see what the obvious difference is: 8870m is a discrete GPU. Iris Pro is an integrated GPU and beats every AMD APU. The fact that you're comparing discrete to integrated is an incorrect comparison.
I am sorry about the tone earlier, but the arguments from the AMD side have been silly. The article was posted and then someone counters with mention of the Kabini. Well, unfortunately, Kabini is a different market segment - as I mentioned it is a laptop chip , it is not a 1-2W tablet chip. Period. The fact of the matter is Bay Trail T is better than every ARM SOC in CPU performance, and the graphics could improve, sure. But that isn't a deal breaker since the total package is what matters, and it is a 1-2W TDP chip. The fact that the CPU on Bay Trail T is so good has good ramifications for Airmont, which is arriving in early 2014 with much improved graphics. Intel is inching closer to having a chip that can best all ARM SOCs, we'll see what happens.
AMD doesn't yet have anything to compete in that power window, maybe they can downclock Temash to do so but they have not thus far.
