Opteron Benchmarked Against Xeon

Posted by CmdrTaco on from the round-64 dept.

jbmnuke writes "Tom's Hardware has posted a review of AMD's Opteron v. Intels Xeon." Nothing gets the blood pumping like a whole new generation of CPUs to compare numbers to, right? Update: 04/22 12:35 GMT by H : And there's the official benchmarks as well, with more coming - like Linux Magazine and Newsforge

  1. Old news... by G3ckoG33k · · Score: 5, Informative

    Suddenly, I feel this is old news... It came out five hours ago for gossake!

    Nonetheless here is the condensed version:

    _____________Server_______Workstation
    Opteron__ ____Very good____Good
    Xeon_________Good_________Very Good

  2. Impressive SMP scaling by Anonymous Coward · · Score: 5, Informative

    Check the Spec benchmarks here.

    SpecFP_rate, 2CPUs:
    Itanium2 1GHz: 30.7
    Opteron 1.8GHz: 26.7

    SpecFP_rate, 4CPUs:
    Itanium2 1GHz: 49.3
    Opteron 1.8GHz: 49.2

    Here we see the beauty of AMDs integrated memory contoller. Despite that 1GHz Itanium2 is a $4000 chip and has 3MB of cache, doubling the number of CPUs increase performance only by 60% because Itanium2 uses shared bus.

    Opteron gets impressive 84% improvement because
    memory bandwidth increases as more CPUs are added.

    In SpecInt Opteron is much more faster than more expensive Itanium2.

  4. Re:AMD Faster Speed markings? by sprouty76 · · Score: 5, Informative
    Actually, I read that the numbers were based on the equivalent performance of an old Thunderbird Athlon (non-XP), rather than pentiums.

    However, there's little doubt that they are meant to be compared to pentiums, and you raise an interesting point. Even stranger would be - what happened if intel adopted the same scheme? Then they'd both basically be making up numbers!

  5. Another review at Ace's Hardware by lorax · · Score: 5, Informative

    Ace's hardware as an in-depth review as well, and it isn't slashdotted.
