Quem disse isso foi a Microsoft. Um dos grande comentários ultimamente é que as instruções de 64 bits da AMD e Intel são muito parecidas. Segundo Bob Muglia que vem a ser o "Microsoft senior vice president" existem diferenças entre os dois, e mais, segundo ele a AMD realizou um bom trabalho com os seus processadores. Ele disse que a AMD foi melhor que a Intel, mas que a Intel continuará o aprimoramento de suas instruções EM64T. Vejam parte da entrevista:
Intel EM64T vs. AMD64
Paul: Are you seeing any difference between AMD's [64-bit] stuff and Intel's stuff?
BM: Yes. [Smiles]
Paul: Would you care to clarify that? [Laughs]
BM: Well, AMD has done a good job ...
[Laughter]
Paul: OK, I realize these companies are both important partners...
BM: I think both have invested very heavily... and I'm sure that customers will be happy with either solution. Paul: All righty.
[Laughter]
BM: Are there differences? Yes, there are differences. Paul: OK, so how do these companies differentiate their 64-bit products?
BM: So there are some things that AMD's done that Intel hasn't done, and I'm sure Intel will continue to invest here, and will do a really good job. AMD led the way on this one. There's no doubt they led the way on this one.
Paul: Right, I thought [AMD64] was going to be the orphaned [microprocessor] of the decade, the next Alpha...
BM: Oh I didn't think so. But do you know why I knew? Because of Dave.
Paul: Dave Cutler.
BM: Yeah, Dave's been all over this. Dave worked really closely with to design the chip. He was trying to get something that was really compatible and the problem that we have is that we want to support all of our applications totally. And these chips are just fantastic for that.
Paul: It's almost like applying the Microsoft model to [chip design]. The Itanium, for all its advantages, just couldn't run the installed base very well.
BM: No, not very well.
Paul: And it never will.
BM: No.
Paul: So back to the core OS benefits, again, where do these figures come from?
BM: This is our own internal testing. It's pretty remarkable what we're seeing, actually.
JP: There are a bunch of address space limitations to 32-bit, and for certain functions, you just can't get enough memory. And with a certain amount of memory, all of those limitations go away.
BM: We tested a whole series of workloads. Some workloads just don't benefit that much from 64-bits, but having a 64-bit OS on there gives you certain advantages. Other workloads--even if the app is 32-bit--you get a huge benefit by running on a 64-bit OS. The most extreme example of that is Terminal Services, because it's limited by the amount of physical memory in the box, in terms of capacity. So even though it's a 32-bit application, you can now run a lot more users simultaneously on the same computer. And these four-ways are blazingly fast.
Paul: These machines we're talking about. Are they out now, or are they coming out next year?
BM: They're out now. They're AMD Opteron systems.
Paul: Physically, what is the limit on RAM in today's Opteron machines?
BM: It's a physical limit based on the number of slots in the machine. I'm not sure what that number is. I'm sure you're going to see 32 GB systems today.
Paul: Compared to 4 GB on 32-bit.
BM: Well, three really. Though we can do more with address extensions. It's funky. Kind of like the old school memory extender stuff.
Paul: Ah yes, the good old days. But wow, 32 GB of RAM this year.
BM: Sure. I mean, we've actually built Itanium systems [at Microsoft], these really big systems, with a terabyte of RAM in them.

Hehehe, Intel ta se lambuzando toda ultimamente.
