AMD Reveals Plans to Move Beyond the Core Race
J. Dzhugashvili writes "The Tech Report has caught wind of AMD's plans for processors over the coming years. Intel may be counting on cramming 'tens to hundreds' of cores in future CPUs, but AMD thinks the core race is just a repeat of the megahertz race that took place a few years ago. Instead, AMD is counting on Accelerated Processing Units, chips that mix and match general-purpose CPU cores with dedicated application processors for graphics and other tasks. In the meantime, AMD is cooking up some new desktop and mobile processors that it hopes will give Intel a run for its money."
AMD is smaller obviously, so it has fewer resources...but with those Alpha scientists, they're going to keep going strongly. It's just a matter of time with business directives like this before AMD takes over. They've been having some really cool ideas...and a few more over a few years, the innovators may win. And no, I'm not an AMD fanboi, but I have talked to some architects from IBM and Intel, and they do concur.
The most interesting thing for me was the mention of "Hybrid Graphics":It also looks like they're also extending the Fusion concept along Cell-like lines, with additional cores for non CPU or GPU purposes.
Their road map through 2008 only talks about up to quad core, although I assume this means CPU cores (I'm not sure that I would accept a CPU+GPU on a single die branded as a 'dual-core' chip). I think the Cell has eight cores, but due to yield issues not all are enabled in a PS3, and they are not all functionally equivalent. I don't know if this is the case for the Cell-based IBM blades, though.
The roadmap basically looks like periodic refreshing of the product line reducing power consumption with each iteration, which is where I think Intel have got a head-start on AMD. However, if AMD can sort out the yield issues, and compilers and developers begin to take advantage of these "associate" cores in Cell and future AMD architectures, then maybe Intel will have turned out to have missed a trick, as they did with x86-64.

FSB 1333 (333 QDR) seems to be holding up well for 4 cores at the moment. It only really seems to be much of an issue in the 4+ socket world (which is admittedly lucrative). You are correct in the sense that Intel stands to gain from a move to a hypertransport-like system, but that only raises the counter-issue: If Intel has the performance lead now, even with the FSB issues, then AMD's 07-08 products have to hit it out of the park to beat Intel's chips without that handicap.
The real issue is feature size. AMD is hurt badly by being consistently behind on that. Intel's been at 65 nm for a while now, and AMD is only now releasing 65 nm parts. Intel will be at 45 nm in some lines by this time next year, while AMD is a year behind them. Feature size brings with it higher yields (more chips per wafer) once you work the kinks out, lower heat, and more transistors per chip. That's the game winner right there, unless one of them shoots themselves in the foot again, like Netburst.
