PA-RISC Processors processor

PA-8800 (Mako)


The dual-core PA-8800 Mako processor, introduced in 2004, is a PA-RISC 2.0 64-bit processor from HP that integrated two seperate PA-8700 cores on a single die with very large off-die L2 caches. The clock speed was only increased slightly, while the processor bus interface was redesigned to use the Itanium 2 bus. Mako was supposed to breathe fresh life in the PA-RISC line, though it had strong internal competition from the Itanium line, a VLIW development from HP and Intel, and was not marketed much. Most systems supporting PA-8800s use the HP zx1 chipset and could be hardware-upgraded to use Itanium 2 IA64 processors.
