4-socket Barcelona v. Tigerton performance comments from NDA'd reviewer at Anandtech Depending upon the application, Barcelona clock for clock is equal to Clovertown or just a tad faster in some areas and in others it is 20%+ (heavy emphasis on "plus" until Monday, ) faster. I have to say that final silicon is looking really nice at this point, especially in memory sensitive applications where this processor shines, but core speeds need to come up in a hurry to compete with Tigerton in general server applications. The memory bandwidth numbers we noticed are a little surprising considering the results in certain memory intensive applications. The latencies are much improved over the last core stepping we looked at as is pure throughput which makes you think twice about the relationship between bandwidth and performance in general from this CPU. My personal opinion is that if AMD had hit their original launch targets and speeds, the server market would be incredibly competitive at this point with Tigerton being a much needed response to Barcelona. As it stands, AMD is going to have an uphill battle at this time. But this is all subjective thinking from a guy who tried to compare an engine to a CPU, but maybe the results on Monday will clarify some of the observations I was trying to convey without breaking the rules. forums.anandtech.com Wow. So Intel has managed to capture a large number of 4-socket benchmark wins with Tigerton, and Barc won't be winning them back without more clock. Rather impressive for a "non-native quad core" with an "outdated FSB". :) "clock-for-clock" just doesn't cut it when your competitor is about 1GHz faster.
