So Intel has caught up with AMD by copying their 64 bit instruction set and copying their architecture.

But AMD has basically been milking three year year old technology, and probably not standing still in R&D.

By the way, I notice that current motherboards will not boot the Duo. Too bad.

Intel was trying to beat AMD with the Megahertz battle, in the process of doing that they have transitioned their FABS to 65NM chips to reduce heat(this has now given Intel a leg up since AMD is still on 90NM) Intel has given up on the Megahertz war and found that AMD was correct to go with higher instructions per clock... AMD needs to get to 65NM ASAP... Intel 975X chipset supports Core2Dou...

So Intel has caught up with AMD by copying their 64 bit instruction set and copying their architecture.

Some numbers jumped out at me. It was clear that Intel’s EM64T architecture present in the Cyberpower, Dell, and Compaq systems was not helping encoding times in Movie Maker at all while running 64-bit Vista. However, I did see an improvement in Media Player while encoding CDs. Perplexed, I contacted Intel and asked them if they could offer an explanation as to this phenomenon. I was told that different compilers could have been used, and Microsoft may not have optimized certain applications at this point for EM64T. Being that this is a beta release, I am happy to accept this explanation at this point. Moreover, since I did see a marked improvement in audio encoding times, I can at least point to a scenario where an application is taking advantage of Intel’s 64-bit architecture.

So, EM64T isn't an exact copy of AMD's 64bit technology... :)

Although EM64T is pretty much the same as the AMD 64 bit stuff, the other part of your comment is false. Core Duo is not in any way a copy of AMD architecture. Intel got sidetracked going after MHz/GHz for a while. Core Duo is based on (with enhancements) the older Intel Pentium III architecture, not AMD's architecture.
