Intel's Pentium 4 3.4GHz processors
"changes from the older Northwood core are too complex to summarize easily. That said, I'll make a feeble attempt. Prescott includes larger caches, a much deeper main pipeline, SSE3 instructions, improved data prefetching, revised Hyper-Threading, and enough microarchitectural tweaks to kill a horse. Most importantly, Prescott is manufactured using Intel's new 90nm fabrication process, making it a smaller chip than the 130nm Northwood, despite having a much higher transistor count."
