Comparison: Sockel 478 And Socket 775
Old versus new: LGA775 (left) and PGA478.
Prescott For Socket 775
The inside of the new processor has not changed - it's still a Pentium 4 Prescott. Intel's message is clear: Processors that are faster than the recently announced 3.4 GHz models will not be released for socket 478. CPUs that run at 3.6 GHz or faster will require the new platform with socket 775. On the other hand, the initial clock speed for the 775 platform will be 2.8 GHz. In the middle of this year, P4 Extreme Editions will complete the upper range of Intel's processor portfolio for socket 775.
