While benchmarking our test platforms with Sysmark, we got some unexpected results that we are still investigating more in detail. It seems the bigger cache and higher FSB of the Barton severly skew the results of this popular benchmark. We suspect AMD improved the Barton core specifically to perform better on this benchmark. Therefore, we refrain from publishing our results until AMD can give us a a good explication why the Barton outperforms the P4 on this test.
