AMD cpu question

Longshot · 2004-04-05, 02:16

Which CPU is more efficient in running Prime95. The XP2800+ Thoroughbred with 256 L2 cache and a 2.25 GHz speed, or the XP2800+ Barton with 512 L2 cache and a 2.08 GHz speed? Thanks.

Using Prime95, the Tbred and Barton perform at about the same level. So I'd take the higher clocked one.

If you want to do some OC'ing, go for a mobile XP-2500+ (or 2600+). Some people reached 2.6GHz on air and more with watercooling.

The benchmark thread (http://mersenneforum.org/showthread....9&page=3&pp=25) shows how the Tbred and Barton are performing. But don't compare results of Prime95 v22.12 with more recent ones (e.g. v23.5). The 2.33GHz Tbred shown in this thread, performs like an A64 3000+.

Here is a thread that compares XP2600+ Barton with XP2600+ Tbred: http://www.mersenneforum.org/showthread.php?t=1367

The same result: Cache size has no effect. After normalizing the results (to equal clock frequencies) they are the same.

Wow, I am very happy seeing that a benchmark I contributed proved to be useful to someone after so long time. I vow to contribute more benchmarks and CPU comparisons whenever I buy a new CPU :)
