Tom's Hardware was careful to say that the new Intel Conroe dual-core, 64-bit desktop chip set didn't lose to AMD's primo Athlon 64 desktop chip because early benchmarking was orchestrated primarily as a press event by Intel. "Not optimal" is the language the venerable Tom's uses to describe the testing environment.
Nonetheless, the early news is, as anticipated, good for Intel. Tom's is clearly impressed with the Conroe Core 2 Duo architecture, which shares a large L2 cache between its two processors. Among other Conroe features that win high marks: The processor can adjust clock rate based on load, cutting down on heat output and energy demands.
Expect conflicting benchmarking data backed by AMD shortly.
