Quad-core AMD chips to run faster than expected?

Last week, we heard launch clock speeds for AMD's upcoming quad-core processors would range from 2.2GHz to 2.6GHz, and that Socket AM2 quad-core chips would only run as fast as 2.4GHz. The Inquirer now reports AMD has had some nice surprises with its latest B0 stepping of the quad-core silicon. In fact, folks at AMD's campus in Austin were so pleasantly surprised they were reportedly "dancing in the aisles" from the results of the latest stepping.

The Inq says the new silicon allows for a "massive gain in frequency" of as much as a half gigahertz, and AMD fans can look forward to five "Phenom" variants at launch: quad-core models clocked at 2.6, 2.7, and 2.9GHz, as well as one dual-core model clocked at 2.7GHz and a Quad FX-bound Socket F chip with a stock speed of 2.8GHz. The memory controller in B0 chips is also said to have come in "way better than expected," although The Inq doesn't elaborate on the subject. AMD's new microarchitecture is expected to deliver much higher performance per clock than its current CPUs, so the higher clock frequencies could pay big performance dividends.
