Beans spilled on Presler Extreme Edition CPU

Mike Magee has laid out in some detail Intel's plans for its first Pentium Extreme Edition processor based on the new 65nm "Presler" core. Presler's the one with two Netburst processors stuffed together on a single package. Mike says the Extreme Edition 955 will run at 3.46GHz on a 1066MHz front-side bus, and each core will pack 2MB of L2 cache onboard. With Hyper-Threading active, this puppy will look to the OS like four processors, and it may be a pretty desirable CPU, at least compared to Intel's current Extreme Edition 840. The Pentium 4 600 series doesn't benefit much from its larger 2MB L2 cache in current desktop applications, but larger caches and multiprocessing have generally gone together well. We're told to expect the new Extreme Edition in the first quarter of '06.

I'm curious to see how well the Netburst design translates to Intel's 65nm process and the dual-chip package. These processors may well run at higher clock speeds, with lower power consumption, and offer better overall performance. Whether that makes 'em good enough to match up with the Athlon 64 X2, well, that is another story.
