Ars offers POWER5 details

Ars Technica has posted an , including IBM's POWER5, Sun's UltraSparc IV, and Transmeta's Efficeon: "Of great interest to the Mac community was IBM's disclosure of more details on the upcoming POWER5. POWER5 is an evolutionary advance over POWER4....the big news is that POWER5 is an SMT (a.k.a. "hyperthreading") design, with each core capable of running two threads at once. This means that a single dual-core POWER5 chip will look like four logical processors to the OS."

    new processors coming

    sounds like I should hold off replacing my IIci until those multithreading hyper things come out.

    I wonder if they'll be doing upgrade cards for the ole 68030's?

    RE:

    Just for fun...imagine a Pismo or even an old Wallstreet at around 2Ghz...
    Even more fun: A G5 (Power5) powerbook with dual processors for video editing.

    Then I woke up.

    multi-core

    Funny thing is that multi-core chips were absolutely part of the moto roadmap.. just never even close to being delivered. The IBM roadmap seems to preclude multi-core chips for 970, 980, 990 derivatives of their POWER4,5 and 6. It seems the plan is for multicore in the POWER line, single core, multiple chips in the 9xx series. I'd jump for joy to be proven wrong!

    Re: new processors

    Wasn't the IIci a 68020 chip?

    Power5

    Hmmm. Those would be nice in the X-serve. Now that would be a complement to the G5 desktops and laptops. Maybe serving a bank of iMac G5's with an airport connection. Nice for home use, me thinks.

    I am glad to see

    Many Lisa users still holding out until something powerful enough to switch comes out. If Lisa ran OSX I could be running UT2003 at 100+fps. L8R
