Intel's new driver fixes some issues on some of those games. Again, we'll see them rebenched with Intel's updated drivers soon enough. Also, you do know that you will NOT get more performance web browsing or watching a video on an AMD system right? If you don't know that, then you misinterpreted the benchmarks.

Cinebench 1.49 vs. .77 for Trinity - That is DOUBLE performance for Intel in single threaded.
Cinebench MT - 6.84 vs. 2.05 - Tha is OVER 3x the performance
PCMarks - 6695 vs. 2776 - That is almost 3x as much performance
x.264 2nd pass - 36.23 vs. 13 - Again, Intel almost 3x faster.
AMD wins DirectX 11 by a but loses in DirectX 9. So yes, AMD drivers are better... for now. I'm curious to see if the new drivers will make an improvement in DX11.
Anyway, Intel is over 2X faster on the CPU side while losing by 20% on gaming titles that no one is going to play with an integrated GPU. Somehow you justify this as a decision to buy AMD???????????????????
There is zero evidence to show that OpenCL makes AMD faster than Intel solutions although it helps on a few titles like HandBrake. In fact, even in HandBrake though, the Intel solution STILL BEATS THE AMD solution according to your own link. 19 to 15. While AMD got more performance from OpenCL (due to their drivers), Intel still wins by 30%!
So... unfortunately, you didn't show me anything in those links that makes the AMD solution better except for a situation that people just don't do (play games on a laptop with iGPU). Even then, a few titles were better on Intel and the new Intel drivers fix situations in some of the other games.
Also, H4000 is going in all laptops including low power ones. HD4000 was made for the mobile platform. It really is useless on the desktop. Haswell will take care of the desktop graphics issue. HD4000 competes with AMD's latest on the mobile side which is what it was supposed to do. AMD's strength is in its price. I like AMD at a very low price, but there is no way I'm going to buy something at HALF the CPU performance just to get a slightly better iGPU at full wattage. At 17W, I actually think Intel's solution will be slightly faster than AMD because they can't solve their power issues. This is why Ultrabooks will not be a very good market for AMD until the next generation of AMD processors which will have GCN and an updated CPU architecture.
