HP Shows Off PA-8800 SMP-On-A-Chip CPU Plans
Eric^2 writes: "At last week's MicroProcessor Forum, HP's David J. C. Johnson unveiled the details of HP's latest RISC processor destined to redefine performance in Server-Class processors. Following a relatively simple strategy, the PA-8800 processor combines two PA-8700 cores on a single chip to enable symmetric multiprocessing (SMP) on a single processor. Aside from bumping the core speed up to an initial 1 GHz, enhancements include the addition of combined 35 MB L1+L2 cache. The article contains the full text. AMD, please steal an idea..."
...a 1 GHZ processor may not sound like much, even in this dual-core configuration, but keep in mind that this is a RISC processor. None of that Super-mega-ultra-long-50-bazillion-stage pipeline crap that Intel uses to pump up their MHz rating. The article kind of sells this point a little bit short. The RISC architecture allows this processor to do roughly twice as much work in the same amount of time - or, to put it in a more concrete scenario: imagine a pair of 2GHz Pentium 4's running in SMP configuration.
Now that's FAST .
