Ali: What you need is to look for trends. And the trend for A4 does not look very good. From what I've seen so far, the trend looks very good. What do you mean, when you say it doesn't look good? A4 boosts performance over Tbird in virtually all the benchmarks where P4 was strong(er than Tbird). Additionally, many of these benchmarks are the ones that suffer the most when using SDRAM. Seems pretty darn close to perfect to me. (Yes, from a selling point of view, a ten or twenty percent increase in frequency would probably have been a lot better, but messing too much with the pipeline is a costly affair). -fyo

Re: And the trend for A4 does not look very good. The trend for A4 looks just fine to me. 1.2 -> 1.4 next month. To keep up, Intel needs: 1.7 -> 2.0 next month. AMD moving to 1.73 for end of year: Intel needs 2.45 by end of year. To keep up in GHZ ops (and performance) Intel needs 2.6GHZ nominal clock by end of year - which they aren't expected to have. What trend are you looking at?

Ali, re:<What you need is to look for trends. And the trend for A4 does not look very good.> I've done this analysis several times myself and found that the TBird at 1.2 is scaling as well as the P4 at 1.5. There is an exception in that the 1.7 P4 actually improves benchmark scores more than would be expected from the increase in clock speed. But that is a one-time IPC increase not nearly as large as the improvement in IPC of A4 vs. Athlon. So what do you mean by the "trend for A4?" Clearly a 1.5 GHz A4 will outperform a 2 GHz P4 by far more than a 1.4 GHz TBird outperforms a 1.7 GHz P4. And the competition is NOT P4 systems with dual RDRAM channels, but P4 systems with SDRAM and that competition will be a joke. Petz
