I meant single-thread performance, sorry if I didn't make that clear. Single-thread performance is ultimately the most important thing in computer performance, because you can always parallelize chips later. I'd much rather have one single Pentium 4 than a couple hundred 486s in parallel. >I would accept that whether a higher IPC or higher clockability is better is >*not* a settled question, so saying that the P4 is inferior, because it employs >an inferior strategy is unwarranted. I believe it is a settled question. Microprocessor people call this the brainiac vs. speed demon contest, and it was won by speed demons. There is no question in my mind that Intel is doing the right thing by going after higher clock speeds. http://www.mdronline.com/mpr_public/editorials/edit13_17.html -Tom
