AMD AnandTech takes a look at AMD's new Phenom. "If you were looking for a changing of the guard today it's just not going to happen. Phenom is, clock for clock, slower than Core 2 and the chips aren't yet yielding well enough to boost clock speeds above what Intel is capable of. While AMD just introduced its first 2.2GHz and 2.3GHz quad-core CPUs today, Intel previewed its first 3.2GHz quad-core chips. We were expecting Intel to retain the high end performance crown, but also expected AMD to chip away at the lower end of the quad-core market - today's launch confirms that Intel is still the king of the quad-core market."

RE[6]: low yields

Member since:

Barcelona is a new processor so some problems are to be expected, AMD probably expected problems so deliberately didn't produce many chips. IBM didn't appear to have any problems with POWER6 or Cell, both being produced on 65nm so I doubt it's anything to do with the process.

POWER chips don't sell in very high volumes, so they're not a good judge of yield.

As for Cell, you've got the main core and 7 smaller cores. The chip is designed with extra smaller cores that get disabled at the factory to deal with manufacturing errors. That may be the reason AMD is/will be offering triple core processors, but with an x86 you can't really do things like that to anywhere near the same extent.
