Makes you wonder what all the fuss was about.

Thanks for posting the links. One question, however, about the Anandtech
review. Why does the writer think that a a micro-op is only one byte long, and see the 64 KByte AMD instruction cache as necessarily larger than the Intel 12 Kmicro-op cache? As far as I know, the rest of the review may be spot on, but this item does make me wonder. -- Phil Weldon, pweldonatmindjumpdotcom For communication, replace "at" with the 'at sign' replace "mindjump" with "mindspring." replace "dot" with "."

As far as I know, the rest of the review may be spot on, but this item does make me wonder. The "average" x86 instruction is 2.5 bytes long (give or take), so a 12k-*instruction* cache would be approximately equavalent to a 32kbyte cache. However, a lot of x86 instructions decode to multiple uops on the P4 (eg: those that access memory), which overall means that the trace cache is equavalent to somewhere between an 8kb and 24kb instruction cache, depending on the code that's being executed. Someone did some tests at some point (slowly increased the size of a loop and plotted the results) which verified this, but I can't find any results. If anyone has a P4 handy, I can quickly whip up a program that would do it.

Sounds straight enough for me!

What really astonishes me is that they also release a 533MHz 2.8E Prescott without HT. What's the point -- for machines that can't do faster than 133MHz bus speed, the Northwood 2.8 and 3.06HT are faster -- the latter quite a bit faster, and at about the same price. Unless SSE3 makes a *gargantuan* impact, I can't imagine any value whatsoever in the more power-hungry and slower Prescott 2.8E. Regards, -- *Art |
