Barcelona Benchmarks

An interesting write up recently in tech report on Barcelona...

The bottom line is this - in the highly business oriented benchmark SPECjbb2005 the opterons pulled ahead of their competing Intel parts. In some of the scientific benchmarks such as MyriMatch the Opteron also performed well. However when it comes to raw compute the chips don't perform that well.

Another item of interest is the single threaded performance of the 2300 parts in benchmarks such as POV-Ray. The new chips actually finish last among Intel AND previous generation AMD parts.

This tells me that the plumbing in the new chips is exceptional. The raw core performance seems to be lagging, but the internals must be able to handle IO very, very well to keep pace with Intel.

Overall - they still lag far behind Intel based on these test benchmarks.

For those of us that game this is not good news. As I wrote a while ago gaming performance is largely dictated by the performance of core and does not see much benefit from multiple processors. If the FX-90's don't see a significant boost on raw core performance we will find that most of games will perform worse - not better than they do now.
