sorry my friend, but thats totally incorrect. go read up on it over at wikipedia
http://en.wikipedia.org/wiki/Amd
intel built their own 64bit set for the itanium chips which were a flop.
Wikipedia basically says what I already did. AMD were forced to reverse engineer the Intel 80386, and they called this product am386. This was because intel allowed them to manufacture 8086, 186, and 286 under license, but they revoked the license so AMD would be unable to make an 80386 clone. (AMD had no design influence over 8086/186/286, they just had licensed clones), and they were fighting intel in the courts from 386 to present day, so certainly no cooperation there.
You'll even notice if you look at the images on Wiki, the AMD 286 processor is stamped (c) intel.
As I said AMD reverse engineered i80386 as a ground up 'clean room' design. Intels lawyers couldnt block this.
I didnt say anything at all about the Itanium IA-64. I said intel did a 'clean room' reverse engineering of AMD's 64bit extensions which Intel named EM64T and unlike IA-64 they are not a flop, and it doesnt need a license to use this technology, and if AMD found a way to say that the clean room reverse engineering wasnt legal, that would be contrary to what they did themselves in 1991.
Likewise with MMX/SSE/SSE2/SSE3 amd continue to reverse engineer rather than pay up the intel licenses. Seems fair to me that Intel finally got to reverse engineer something of AMD's.
To be honest, we should be glad that intel ended the License for x86 after the 286. They forced AMD to stop being 'just a fab' and made them innovate, designing their own processors for the first time. If intel had just allowed AMD to continue, the PC market would still be 90% intel, 10% amd, and we would just be choosing between Intel Netburst, or AMD Netburst. The license stiffled innovation, and cutting the ties between Intel, and AMD were probably the best thing that could have happened. Now both companies can design their own systems, and whichever is best gets reverse engineered by the other. (3Dnow died, MMX/SSE lived, AMD64/EM64T is successfull, IA-64 is only used in limited neich markets)
