The chaps over at AnandTech have compared Intel newest server based on the Xeon MP 7130M with the HP DL585, the popular and well-regarded ProLiant. With up to 16 MB of L3-cache, can the new Xeon MP stop AMD's Quad Opteron from grabbing even more market share? Or do we have to wait for Tigerton to arrive?

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.
