the first unveiled posted concerning the direclty SPEC CFP2000 performance comparison between the Pentium 4 and Athlon Thunderbird runs with DDR SDRAM

keep in mind that this SPEC CFP test is more a test of bandwidth to system memory than a CPU test.

a K6-3 450 w/2MB L2 almost beats a PIII-450 because of the high bandwidth L2 and large L3 cache, despite its very poor FPU. This test is an indication of the CPU's ability to do things such as VLDS scientific calculations (Very large data set) but not an indicator of "desktop" level performance.

Basically this test does not emulate Q3A nor MPEG encoding *grin* which is all most ppl use their chips for.

i want some more numbers from more reliable sources, like anand or tom's. Anyways, i can't upgrade and refuse to buy a whole new case for a chip.

i dunno. i use my computer quite a bit (9 hrs at work, 3-4 hours at home) per day. I don't ever encode anything, nor do i play q3a or any other games

my duron 950 is just for surfing the web, playing some mp3's, burning software, and maybe aim/email.

Can you imagine how fast the p4 will be for servers? Once the ecgs (gcc) for linux is optimizing for p4, it will put much smackdown on the athlon, in the server world.

its all about data bandwidth and moving data in my world. Actually my 2 year old xeon 550's with 2 meg l2 die-speed cache, still spank many other processors in real world speed.

Keep in mind, thats really little, 2 meg l2 cache, in the server world. but it is still pretty fast.

Web servers- yes. Bandwidth is prescious.

DB servers and such require intiger calcs which a 1.2Ghz TBird can beat P4 1.4Ghz

IaPuP: Q3A, in fact, is incredibly fast on the Pentium 4, because Q3A is a memory bandwidth hog. Surprisingly, it is nearly unique in this respect pertaining to games, as most others (like UT or Drakan) would, I'm told, show a Tbird/Athlon at 1.20GHz easily outperforming the fastest P4.

BTW, you sure about K6-3's performance in specfp? I know (from "http://www.jc-news.com/parse.cgi?pc/benchmarking/spec/chart95/S7-fp95") that a K6-3 can beat out an equivalently clocked P55c (Pentium MMX), which was a big surprise to me given the P55c's floating point unit, which has twice the throughput of the one on the K6-3. But I didn't know that it squared well against a Katmai. Actually, with the prefetch optimizations in recent Intel compilers, I'd imagine it blows the K6-3 (which contains prefetch instructions, but there aren't any compiler writers out there willing to utilize it) away on specfp.

I'm not talking about sepcfp2k but spec CFP2k

spec cfp2k is different I believe.

I heard a discussion about this. I saw some numbers. now I can't find where they were!! I'd swear I was at aceshardware but it may have been elsewhere.

*shrug*

Sorry I can't back up my unsubstantiated argument.

Take it with a grain of salt because of this but I'm pretty sure its at least mostly true.
