As promised, we are also introducing a real world web server based on Java Server Pages (JSP). The next benchmark is based on the production Ace's Hardware message board, written by Brian Neal and Chris Rijk. This highly optimized jsp real world application uses a 2 GB object cache to minimize database access. As optimized as it may be, building up the message tree or index of the message boards and compressing it with gzip requires quite a bit of CPU power.
The benchmarked software includes:
Although this should be Sun's favored benchmark, the new Xeon Woodcrest is a real party pooper for Sun. A single 80 Watt Woodcrest 3 GHz delivers almost the performance of one T1 at 1 GHz. Luckily for Sun, it is only fair to compare the top model of Intel to Sun's own top model at 1.2 GHz, and Sun should still have a decent advantage when it comes to performance/Watt: the T1 1.2 GHz is about 20% faster than the fastest Woodcrest. However, the days where one 72 W T1 could outperform four Xeon cores while consuming about 4 times less power are over.
The new Xeon 5160, a.k.a. Woodcrest, is making it very hard for Sun to compete on price/performance: four Woodcrest cores are about twice as fast as the 8 core T1. It is interesting to note that the simple T1 core is almost doing as much work per cycle as the massive Opteron. It has twice as many cores, but they are running at half the clockspeed of the Opteron and offering - on average - only 13% lower performance. If we compare the fastest Opteron (2.6 GHz Dual core) with the fastest T1 (1.2 GHz), this proportion shouldn't change much. So a simple 1-way core with 4 threads can do as much work as pretty complex 3-way core with one thread. However, the Woodcrest CPU does not only perform better per clock, it also reaches a 3 GHz clock. Intel beats Sun here in their home territory.
AMD is also in quite a bit of trouble too. If we extrapolate our 2.4 and 2.2 GHz numbers, an Opteron at 3 GHz would still be about 25% slower than our Woodcrest at 3 GHz. Impressive!

I'm not saying the board is particularly stellar.. I'm saying that it's referred to by MSI as a "server" product.ashyanbhog - Thursday, June 8, 2006 - link
Irespective of what MSI says,fact is there were better mainstream boards for Anandtech to choose from if a honest, independent review was their intention
zsdersw - Thursday, June 8, 2006 - link
I.E., your comment belongs under someone else's.. not mine.zsdersw - Thursday, June 8, 2006 - link
And that's completely irrelevant to what I was saying.ashyanbhog - Thursday, June 8, 2006 - link
all I was saying is, its nice to see Intel finally making a comebackbut Anandtech seems have conducted a skewed benchmark that favours Intel, that unfairly increases the performance gap between Opteron and Woodcrest
In the final summary of the review he says
"In one word: Woodcrest rocks!"
There are quite a few holes in the review, the motherboard is just on of them,
I quoted MySQL number errors in my posts above,
just search for "ashyanbhog" in the page and read my earlier comments if you are interested.

What you're saying in general is irrelevant. Intel calls their integrated graphics "high performance" but that doesn't make it so.
MSI calling that a server board is just marketing, it does not represent what a true, high performance server class mobo is all about. Not that it's a bad piece of hardware, it is good for the price to be sure. But it is NOT a server class product.

At a certain price point, it could certainly be a nice entry-level server board.Performance alone isn't what makes a server-class motherboard a server-class motherboard.
ashyanbhog - Thursday, June 8, 2006 - link
One of the motherboards used in this review is a cheap piece that trades performance to keep price low.
Why was that motherboard selected over mainstream server/workstation boards that are proven to offer slightly better performance? Why pick a 250$ MSI board for opteron over $500 boards from Tyan, Iwill, Supermicro or others. The Intel Xeon "Inderwale" gets a $500 board, so price could not have been the issue.
So what's the point in using a Single Channel board for this benchmark, when price was not a limitation?
Single memory channel boards like the one from MSI, are known to offer lower performance than dual / dedicated memory channel boards when used in 2P Opteron configurations. Dual Channel boards are the mainstream boards for 2P Opteron systems. There are plently Server boards available in Dual / dedicated memory lane configuration. There are enough reviews on the net to show the performance diff b/w single memory channel boards and dual memory channel boards
The issue is not about the MSI or its class, the issue is why did Anandtech pick a Single memeory channel board instead of a more mainstream dual memory channel board.
Hope that clears up "zsdersw"'s query

I'm not making excuses for the choices that were made regarding this comparison test. I'm talking about what constitutes a "server-class" motherboard.ashyanbhog - Thursday, June 8, 2006 - link
