When we last used this test the dual 2.2GHz Xeon was on par with the dual Athlon MP 2000+, with Hyper Threading giving it a slight increase in the number of transactions per second that the server could handle.
Here we see that the dual Athlon MP 2100+ is able to outperform the dual Xeon 2.2GHz setup but the fastest 2.4GHz parts manage to take the performance lead once again. Enabling Hyper Threading gives the dual Xeon 2.4 a 10% performance advantage over the DP Athlon MP 2100+ system.
The move to dual 2100+ CPUs results in a 4% performance gain while the jump to dual 2.4GHz Xeons yields a 9% increase over the previous 2.2GHz parts. If we then look at the salability of these two architectures you'll see that for the 4.1% increase in clock speed per CPU, the overall performance of the 2100+ was improved by 4%. This type of scaling is actually almost identical to what we saw on the Xeon platforms as the 9% increase in clock speed per CPU yielded a 9% increase in the performance of the two CPUs combined.
What's very important to note is that the Athlon MP is able to remain this competitive with a 50% smaller cache than the Xeon processors, we'd expect a Barton based Athlon MP core with a 512KB L2 cache to do even better.
We've already analyzed the single processor performance figures you see here in our first Database Server Comparison article.
