IBM z Processors Climb to 5.5 GHz

The core of IBM's venerable mainframe architecture, the z196 chip, is currently shipping as a 5.2 GHz quad-core processor. The next product generation will apparently climb to 5.5 GHz, according to a report published earlier this month by the Wall Street Journal.

There was no clock speed information on the next Power chip, currently called Power7+. Power7 runs at up to 4.14 GHz today and IBM says that the next generation will be 10 to 20 percent faster and it is more than likely that a slight upward adjustment of the clock speed will arrive as well.

IBM's zEnterprise servers have a starting configuration price point of about $75,000 for the z114 (up to 14 processors at 3.8 GHz) and scale into the hundreds of thousands of dollars for z196 systems with 24 processors/96 cores. A single 5.2 GHz quad-core z196 processor, called central processing complex (CPC) is rated at a power consumption of about 300 watts.

In comparison, a 4.14 GHz Power7 chip is rated at 190 watts thermal design power.

    Not X86, so don't really jump to conclusions about the performance. Nor can you natively run Crysis...

    back_by_demandUp to 20% more speed for only 50% more wattage, OMG!!!...Contribute to global warming much? I though performance per watt was supposed to go up not down


    It's like in cars or pretty much any other machine... the higher in performance you get the more unproportional the required power goes.
    Like making a car go from 0 to 40... any small engine can easily do that. Make it go from 160 to 200mph takes some major hardware upgrade :-)

    It's 5.5 GHz continuous clock speed, with mainframe service levels and with obscene amounts of cache. That's not with cores shut off, burst mode, nitrogen cooled with a 5 minute lifespan, etc. -- it's pedal to the floor sheer performance in the world's most reliable server. And every processor is crafted in the U.S. of A.

    Bravo, IBM.
