Re: Itanium Performance

Rob,

You know with big iron that clock speed isn't all that important. Even at 500 Mhz, the Itanium would be faster than current Ultra Sparc II or POWER3 offerings.

For example, the E10000 and the S80 use processors that are clocked about same speed. Both servers perform roughly equally. The difference is that the S80 does it with 24 processors and the E10000 does it with 64 processors. It takes Sun 40 more processors to produce results roughly the same as IBM's.

Basic logic would tell you the E10000 should be 166% faster than the S80 if you only look at the processors.

I'm really curious to see how bad the EPIC architecture cripples the Itanium. I want to see java benchmarks, that's all that's going to matter if it's ever going to be a webserver.

Rob, it amazes me to see how far Alpha has slipped. Weren't you saying last year that 21264 will hit 1 GHz this year? Seems like that won't happen until early next. Even at 733 MHz, I expect Itanium to easily tower above the Alpha.

By the way, remember what I said about Intel worried more about Sun than Alpha? Add IBM's POWER4 to the list of competitors Intel is most worried about.
