<A HREF="http://www6.tomshardware.com/cpu/20040201/" target="_new">http://www6.tomshardware.com/cpu/20040201/</A>When the name Prescott was first heard, people started to assume Pentium 5 was coming, as there are a number of changes differentiate Prescott from the Northwood core: 90 Nm process, 1 MB L2 cache rather than 512 KB, the L1 data cache that was doubled to 16 KB, 13 new instructions referred to as SSE3 and the new pipeline that was extended from 20 to 31 stages, officially part of Intel's NetBurst architecture. The concept sounds familiar, but has its downsides. More on that later.
