IBM Judging by details revealed in a chip conference agenda, the clock frequency race isn't over yet. IBM's Power6 processor will be able to exceed 5 gigahertz in a high-performance mode, and the second-generation Cell Broadband Engine processor from IBM, Sony and Toshiba will run at 6GHz, according to the program for the International Solid State Circuits Conference that begins February 11 in San Francisco.

Power6 for large applications

IBM's Power series has been running large machines and professional applications such as banking, healthcare, and manufacturing quite a while in the zSeries (mainframes), iSeries (midrange), and xSeries (UNIX) lines.

I believe the largest of those was up to 32 processors before the multiple cores were available and I recently read something about 128 cores being utilised. The Power6 will be a great processor where lots of money is available for lots of cooling.

Obviously, desktop machines can't cost $7000 and be sold to consumers. Even the Mac-o-lytes won't buy them. Intel doesn't really sell to IBM's market, so they can produce better desktop processors. The PowerPC 604e was quite a performer compared to the P3 but it didn't go above 350 MHz for consumer machines.

IBM never considered clock speed a priority when they could just add more or special function processors. However, they had 3 GHz G5 samples and we know that those were never repeated in production.

zSeries only has embedded powerpc. z9 has ppc 4x0 in the channels, and service processors. None of the zSeries machines have ever had a Power3/Power4/Power5. The latest mainframe processors are codenamed "bluefire", and they are very distinct from Power.

Lots of z9 info. will be published soon...

xSeries are AMD and Intel only. xSeries is different from the Blade Center and IntelliStation brands.

DS8x000 storage does use Power5, and Power5+.

I believe the largest of those was up to 32 processors before the multiple cores were available and I recently read something about 128 cores being utilised. The Power6 will be a great processor where lots of money is available for lots of cooling.

The biggest machines had...

Power3 = 16 chips/16 cores/16 threads
Power4/+ = 16 chips/32 cores/32 threads
Power5/+ = 32 chips/64 cores/128 threads

In IBM speak, 1 core = 1 processor.
