Ars Dissects POWER5, UltraSparc IV, and Efficeon

Posted by timothy on from the pirate-noise-plural dept.

Burton Max writes "There's an interesting article here at Ars about the POWER5, UltraSparc IV, and Efficeon CPUs. It's a self-styled "overview of three specific upcoming processors: IBM's POWER5, Sun's UltraSparc IV, and Transmeta's Efficeon. " I found the insights as to Efficeon (successor to Crusoe) to be particularly good (although it paints a sad picture of Transmeta, methinks)."

  1. Efficeon has integrated northbridge by chipace · · Score: 2, Redundant

    One detail that they didn't mention was the integrated AGP and DDR memory controller on Efficeon. Blades don't use graphics, so I'm thinking that Efficeon was designed primarily for Japanese laptops.

    Efficeon allows for a low chip count design. That could mean a smaller and more reliable laptop design.
