K7 Benchmarking

Posted by ryuzaki0 on from the re-thinking-next-chip-purchase dept.

Quite a number of people have written in with the word about more specs on the K7, and its performance versus the PIII. Here's a little teaser: the spec K7 FPU performance is 40% faster then the PII. Check out Ace's Hardware for more information.

    Well it appears that the info we had was correct as AMD did show a presentation including bencmarks at the dinner it hosted tonight. I got a little snippet of info from a usenet posting that JC posted and I thought should be posted here as well. Check it out:
    hi,
    I've just returned the dinner meeting at which Dirk Meyer (VP of Eng.
    AMD) had a presentation. My first impression is that K7 looks very promising.
    Mr. Meyer told us that AMD was indeed announcing K7 this month (June
    '99) at 500, 550 and 600 Mhz. It has 22 Million transistors on a 184
    mm square die at .25 micron process.

    The first release of K7 will have 512K of L2 cache at half-speed.
    At 600 MHz, K7 is %115 faster in SpecInt95 than a PIII Xeon 550Mhz
    with 512K full speed cache. At 550 K7 is %106 faster in SpecInt.
    At 600MHz, K7 is %143 faster than the same PIII Xeon at SpecFPBase.
    At 550Mhz, K7 is %136 faster (these numbers are interpolated visually
    from a slide which means 143 was closer to 140 than 150).
    At 3D Winbench 99 V1.2 (null driver) on win98, K7 600 is at %146
    faster than the said PIII Xeon using SSE optimizations.

    There are new Integer SIMD instructions, DSP type instructions for
    MP3, AC (audio) etc. and cache prefetch instructions. Microsoft will
    support 3DNow in an upcoming Visual Studio release.

    At initial launch, there won't be any MP systems. All motherboards
    (from Asus, Biostar, Gigabyte, FIC and one other I couldn't catch)
    will use AMD chipset. Via, ALI and SIS are designing their own
    chipsets to be released before the end of this year.

    These are most of my notes during the one hour presentation and Q&A
    afterwards. All errors are my own. I speak only for myself etc., etc.
    muzo
    What a great day for x86! hehe at least if you arn't Intel. This post was posted at 12:50 AM on June 11th.

    I ate my tag line.
