PA-8700 (PCX-W2)

Overview

The PA-8700 processor is an 64-bit HP PA-RISC processor from HP, released in 2001 building on an enhanced PA-8500 core with several modifications As with other PA-8x00 processors, the logic core is close to the original PA-8000 from 1997. The PA-8700 used significant larger on-chip L1 caches and TLB while switching to a new manufactoring process at IBM helped increase the clock speed. At its time it was one of the largest available commercial processors and one of the first manufactured in Silicon On Insulator.
