Intel Pentium 4 3.0C – The First 800MHz FSB CPUby Anand Lal Shimpi on April 14, 2003 6:30 AM EST

As we expected, the 800MHz FSB improves overall performance between 0 and 12% as you can see by this chart:
Combine the improvement of the 800MHz FSB with the benefits of Hyper Threading and you've got some relatively tempting performance improvements to the Pentium 4, but it's nothing that's going to blow you away. The true benefits of both the 800MHz FSB and Hyper Threading will be realized with Prescott later this year as the processor will push higher frequencies and contain Hyper Threading specific architectural improvements that should improve performance even more.
The introduction of new platforms, the 800MHz FSB and Hyper Threading into the mainstream won't replace the need for higher clocked processors in order to remain competitive, but until AMD can respond with faster Athlon XPs and eventually with the Athlon 64, Intel will be just fine with their new C line of Pentium 4 processors.
