Have a look at : http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3674
(might be old news for some).

Seems like AMD is yet again pushing for a lot of innovation. Firstly they will include two integer clusters per core making one core look like two - think of it as hyper-threading using more hardware (not the bogus intel way of doing it)

Secondly they are wagering a lot on Fusion. By only including integer pipelines in the cores they need to do floating point operations elsewhere. With GPU cores making their way into the CPU they can off load floating point instructions to it. GPUs are much faster at SIMD work anyways. They will all share the same level 3 cache.

Awesome :D !

It remains to be seen where this leaves Nvidia and intel.

Nvidia is in a bit of a bad spot since intel is trying to kill it by not allowing Nvidia chipsets for its CPUs. AMD has released powerful DX11 GPUs and Nvidia is still not at that level. Hopefully they will focus all their power on GPUs from now on - good competitions is always welcome.

intel on the other hand is well known for its inferior GPUs and while it has been dreaming of integrating GPU cores inside its CPUs, the current GMAs just won't cut it. Perhaps looking at intels long history of inelegant haxzor solutions and innovative theft it will take them a little longer to do something similar.
 
Amd = innovate.

How long has this fusion thing been going on for man? When is the release date exactly?
 
Isn't the new 32nm intel launching later this year, launching with a gpu on board.
Kinda takes away some of the hype. Larrabee later on should make a differance.
