X-bit's Athlon 64 performance preview

— 6:56 AM on April 19, 2003

A number of other sites have gone ahead and linked it, and the article itself is still online, so here goes. Should this have been the FNT? X-bit labs has posted an 11 page performance preview of the Athlon 64 2800+. Now this is an engineering sample, mind you, and it is clocked at 1.6GHz. X-bit benchmarks the Athlon 64 against the Athlon XP 2800+ and a similarly clocked Pentium 4. The official release is said to be September, so take these benchmarks with a grain of salt.

Some of us remember what happened when a few sites had early benchmarks of an engineering sample of the original Athlon. The final silicon proved to perform a lot better. Note: the site may be kind of slow probably for the obvious reasons. Thanks to one of you who e-mailed the link. The names have been changed to protect the innocent.

Update Damage: This is really fun, but I am a little concerned about their memory latency numbers. They haven't specified what units those numbers are in, but latency numbers come out of programs like cachemem in CPU cycles. Obviously, processors with higher clock speeds will see more clock cycles pass per second than processors with lower clock speeds. One must convert those numbers into comparable units, such as nanoseconds, in order to compare CPUs at different clock speeds. I do expect the Athlon 64 to have low memory access latencies because of its integrated memory controller, but I don't think the gap will be so great as the X-bit numbers would seem to indicate.

Just my two cents.

Like what we're doing? Pay what you want to support TR and get nifty extra features.
