Well, the AMD 64bit Opteron CPU has shown up to play, the only three reviewsright now are available at
AcesHardware,
AMDZone , and
Tomshardware. From the fewbenchmark images that I was actually able to load it looks like the Opteron beats out the3GHz Xeon chips pretty handily when it comes to server related stuff like running SQL. Ifyou were thinking about running one on your desktop though it's probably not worth it.We'll have to wait and see how the Athlon64 chip shapes up when that one comes along. Ohhey, Tomshardware drew a similar conclusion: In the extensive benchmark tests under Linux Enterprise Server 8 (32-bit as well as 64-bit), the AMD Opteron made a good impression. Especially in the server disciplines, the benchmarks (MySQL, Whetstone, ARC 2D, NPB, etc.) show quite clearly that the Dual Opteron puts the Dual Xeon in its place.
