- Prescott, Prescott, Prescott!

Following on from the launch of Intel's Prescott processors this weekend, there have naturally been a stack of reviews flodding sites across the board of which i've rounded up for you all. In comparison to Northwood, the 90nm process chip looks to be a somewhat mixed bag, at least with respect to performance.

Intel is introducing the new line of P4 procesor based on the Prescott core, the first processor manufactured in a 90 nm process. Main features include a doubling in size of both Level 1 and Level 2 cache as well as the in creased pipeline to the processor core that now consists of 31 pipeline stages. At the same time, a number of enhancements in instructions (SSE3) and functions have been added to the execution units.

The main issues with Prescott appear cache access latencies as well as the longer lead-in times caused by the additional pipeline stages. On the positive side are the reduced manufacturing costs and better scalability with performance. Keep in mind, though, that scalability goes both ways. Compared to Northwood, Prescott runs rather hot and requires excellent cooling.
