The Gigahertz Battle: How Do Today's CPUs Stack Up?

Socket 478

Socket 478 certainly is an oldie and we would have added AMD's socket 462 as well if there were a processor to support 2.4 GHz. Socket 478 was Intel's Pentium 4 socket for the 130- and 90-nm Northwood and Prescott type cores. It was the platform that Intel used to move from 2.0 GHz all the way up to 3.4 GHz. It also was the first platform to accept an Extreme Edition processor.

Intel Pentium 4 Processor "Northwood" (Single Core)

We used a Pentium 4 Northwood processor with 512-kB L2 cache and 2.4 GHz to compare its performance to today's CPUs, which run at the same speed.
