AnandTech took a Mac Pro, which comes with two Dual-Core Xeon (Woodcrest) processors and replaced them with samples of two Quad-Core Xeon (Clovertown) processors.

We grabbed a pair of 2.4GHz Clovertown samples and tossed them in the system, and to our pleasure, they worked just fine. Our samples used a 1066MHz FSB, although we're expecting the final chip to use a 1333MHz FSB, but the most important part of the test is that all 8 cores were detected and functional.

The Mac Pro appeared to run fine with the Quad-Core processors, effectively giving them a 8-Core machine. While they are unable to give performance numbers due to non-disclosure agreements, the machine was reportedly stable. It also gives hope for current Mac Pro owners that they will be able to later upgrade the processors on their machine in the future. Clovertown Quad-core processors are expected to be available in late 2006.
