Conclusion so far
Yes, our testing is not done. We still have to test other databases, and we are running benchmarks with Bea's JVM while you are reading this. Those benchmarks will be presented in our Clovertown - Intel's new quad core server CPU - review. In this review we focused a little more on the actual servers. So what can we conclude so far?
The Xeon 7140MP "Tulsa" is nothing less than a massive improvement over the previous Xeon 7041: it consumes less, performs a lot better (see the SPEC int/fp numbers) and is much less expensive. The new Xeon MP needs fewer optimizations than the Opteron to perform well in Java applications. Or if we look at our preliminary Bea Webrockit numbers, it performs better than the quad Opteron with a highly optimized JVM in applications with a big memory footprint (like SPECjbb2005) thanks to its massive L3 cache. In applications where the large L3 cache doesn't play a big role, the relatively poor server performance of the "NetBurst" architecture becomes visible again: our MySQL benchmark runs a lot better on the AMD Opteron and Intel's newest Core architecture Xeons. Power consumption is still rather high though, and the HP Opteron server consumed over 230W less.
In a nutshell, the new Xeon MP will have a hard time convincing people who are leaning towards an Opteron server or want the best performance/watt. But on the other hand, the decent performance and superior RAS features will keep the customers who desire high availability in the Intel camp, while the previous Xeon MP was such a poor performer that many people had no other choice than the AMD Opteron in the quad socket market.
When "High-end RAS" is less important, the excellent performance of the Xeon 5160 based Supermicro 6015 server shows how much potential the Xeon DP "Clovertown" has. Clovertown is nothing more than two Xeon DP 51xx on one chip, but it could give our quad monsters a hard time. You will find out more very soon....
