Re: Why do you keep worrying about Intel's ASPs?

More good news, Paul.

It looks like DDR is good for a 10%-15% performance boost (I'll call it 12). So if P4 is as fast, clock for clock as Mustang, then a 1.5GHZ P4 on Rambus will be as fast as a 1.3GHZ Mustang on DDR. If P4 is 10% slower, clock for clock, then a 1.3GHZ Mustang will beat a 1.5GHZ P4 by 10%. And if P4 is 20% slower clock for clock, then adding a 12% DDR vs. RDRAM factor means that a 1.7GHZ P4 will perform just about identically to a 1.2GHZ Mustang!

1.7 * .8 = 1.36
1.36 * .88 = 1.197

Do you smell that cooking?

It's Intel's Goose!

Conclusion

DDR SDRAM is here to stay. It is a very cost effective and high-performance solution, even for Pentium III systems which are limited by the FSB frequency. People who want to buy a whole new PIII system may prefer a solution with DDR SDRAM, as it is poised to be a very popular memory technology in the next years. In addition to inexpensive modules, many chipsets supporting DDR are due to arrive shortly, including those from AMD, VIA, Ali, and SiS.

Of course, our review does not show the full potential of DDR SDRAM, as systems with larger CPU to chipset pipelines, such as the Athlon and Pentium 4, will benefit much more substantially. One of our sources told us that PC2100 DDR SDRAM offers a 17% (!) boost when running Quake 3 (16 bit) compared to a typical Athlon system with PC133 SDRAM. That is a larger increase than you would see from an upgrade to a 1.1 Ghz Athlon from an 800 Mhz chip.
