Jim,

If those benchmarks are true the P4 looks like a DISASTER...

I suspect that production systems will benchmark somewhat better. 20% is a reasonable IPC delta for P4 vs. T-Bird.

The big question for P4 will be clock speed. If they can ramp it up quickly to 2GHz, it will be competitive with AMD's offerings. What bothers me about the Willy architecture is not the probable low IPC, but rather the tradeoffs (double speed ALU, 2-cycle cache) that potentially impact clock speed.

Had they gone all out for GHz, (not worrying too much about IPC), they might have hit 2-3GHz right out of the chute, which would have made Willy a killer product.

Jim,

Maybe Mhz won't sell after all...<G>

If the benchmarks are anywhere close to reality (which I highly doubt), Willy will present the most serious threat to the validity of McMannis law "MHz sells".

I guess you would not be terribly upset if your law doesn't hold. <g>
