Intel "East Fork" Technology Migration 165
Hack Jandy writes "When Intel's Centrino platform first unveiled, industry experts were surprised to see such great performance of the Pentium M, based off Intel's P6 (Pentium III) architecture. According to sources in the industry, Intel has officially adopted the approach to migrating Pentium M to the desktop (hence, "East Fork") to offset some of its Pentium 4 processor sales. Cheaper, slower, cooler, but higher performing processors are on the way to an Intel desktop near you!"

From what I've seen at Intel's developer forums, they're working on some radically different architecture. Something that isn't von Neumann at all. They're calling it "massively parallel" but the industry seems to think that this means multiple cores on one chip. I think that it means thousands or millions of "processing elements" on one chip (think really small processing elements). Their claim is that they'll be able to apply this architecture to everything from mobile to high-end servers simply by adding or subtracting elements as power constraints allow.

Don't think so (Score:4, Interesting)
Intel has basically been hanging itself with the awful lot of rope their own marketting gave them. The "MHz is everything" marketting was an easy thing to push, since most people actually _want_ one number that tells them everything about a CPU.
(True story: I actually spent some time arguing with a marketroid about it, and gave up. He was arguing that it must be Anantech's and everyone else's benchmarks that are at fault, because CPU A is in some apps 50% faster than CPU B, in some apps equal, and in some apps actually a little slower. "It can't be! If CPU A is X% faster than CPU B, it must be X% faster in everything!" Any explanations about differences in CPU architecture and such, went right above his head.)
So it was easy for Intel to push the MHz as the one true speed indicator. And for a while all they had to do was keep putting out CPUs with more and more MHz.
Except after a while it became a trap. Any new design _had_ to be higher MHz, or have Intel's own marketting working against it. All those many millions that went into telling people "buy a higher clocked CPU", now would basically tell them "don't buy the newest Intel CPU chip", if Intel made one with less MHz.
And now Intel finally _has_ to find a way out of the hole it dug itself into.
As for Cyrix (now VIA), it was never really a problem for Intel. Cyrix just fell behind performance-wise on its own. The last proper Cyrix versions were already falling beind in integer performance too, but it was their floating point performance that was abysmal. So what killed Cyrix was not as much Intel, as games going 3D: now everyone had benchmarks everywhere, clearly showing the Cyrix as barely crawling.
And Via's versions fell behind even more. They aren't just slower in MHz, they're also slower _per_ MHz. Other than being low power, they just suck.
And it's not that VIA really _wants_ to be the poor-man's niche, for Chinese families who can't afford an Intel or AMD. People find such niches to survive, but noone really wants to _stay_ in such a niche. Noone actually wants to sell their top CPU at $30 or less, instead of, say, the $600+ that an Athlon 64 FX sells for.
So if VIA could break out of that unprofitable niche, believe me, they would. The problem is simply that they can't.
