Data Warehouse Test Explained
We are always looking to improve the quality of our reviews and as a result, we have added a new Stress Test to our suite.
This "Data Warehouse" test is focused on large record sets with plenty of aggregation. This test is based on a system that we developed to track and manage Request statistics for www.AnandTech.com and Forums.AnandTech.com. It tracks statistics like Requests/Hour, Requests/Hour/IP Address, Unique IP Addresses/Hour, Unique Users/Hour, Daily Browser stats, etc. These stats are further summarized by site, i.e.: www or Forums.
As with the other Stress Tests, each test was repeated three times and the average between the three tests was used. For this Data Warehouse Stress Test, we defined a quantity of work to complete and measured how long each platform required to process the workload.
So, to ensure that IO was not the bottleneck, each test was started with a database, including tempdb, which had already been expanded so that autogrow activity did not occur during the test. During the execution of the tests, there were no applications running on the server or monitoring software. Task Manager, Profiler, and Performance Monitor where used when establishing the baseline for the test, but never during execution of the tests.
At the beginning of each platform, the server was rebooted to ensure a clean and consistent environment. The database was always copied to the 8 disk RAID 0 array with no other files present to ensure that file placement and fragmentation was consistent between runs. In between each of the three tests, the database was deleted, the original database was copied again to the array, and SQL Server was restarted.
There is no "client" required for this test. The workload is initiated by a stored procedure call from Query Analyzer.

Sheesh, the workstation benches still aren't up? :(More people are interested in the workstation benchmarks than database I'd wager because it's a better showcase for the new enhancements.
How long will we have to wait?

snorre, proper? It is proper in terms of the Windows world since 64 bit DOES NOT EXIST :). If you want to see 64bit linux coverage as said in these comments and in the article view the linux section or Johans work in the IT section.snorre - Tuesday, February 15, 2005 - link
I'd like to see a proper Xeon DP 2M vs Opteron 252 review, since MS SQL 32-bit benchmarks are only of limited interest. When will we see this?Are there any proper Opteron 252 reviews out there?

#70, you said it. it's the cost. cost is my killer.sure ddr2 costs more than ddr but i hate upgrading my whole setup just to get new momory. right now i'm running a pc133 setup and cannot upgrade even if i wanted to (and believe me... i want to). i know that low latency is what the hammer architecture wants but doesn't regitered memory increase latencies... and what is registered memory anyway?

There was a few questions about single or dual in here, I had answered that but to clarify all testing was DUAL processor.Jason Clark - Tuesday, February 15, 2005 - link
One thing to remember with the Tyan bios is it is pre-production. We'll post info as soon as we have it.Jason Clark - Tuesday, February 15, 2005 - link
We're working with Tyan on the 1GHz HT issue, if we get a new bios that supports it we will re-test and post our results..Cheers.

"i'm interested in number cruncing and games and rendering, i.e. a workstation not a server"Why would you not want registered memory then? Contrary to popular opinion, it does not affect the speed...only the cost.
For gaming, dual systems are no help at all (unless you're running a game server) with todays software. For professional rendering, you absolutely WANT registered memory!
DDR2 would actually be no speed increase at all for AMD64 systems, and none yet for Intel systems. Not until the memory speeds get much higher will we see any benefit from DDR2...
XDR is also not a good match for the AMD chips because of the high latency. AMD chips are NOT bandwidth constrained but ARE latency sensitive (meaning that increasing memory speeds does very little, while increasing latency makes them much worse).
The only real issue of registered memory is the cost, and if that is the problem I would suggest a high end A64 939 SLI board (e.g. Asus A8N-SLI), and upgrade to dual core in September or so...

i'm interested in number cruncing and games and rendering, i.e. a workstation not a server. unforutnately the integrated memory controller of the amd hammers are both their strengths and weaknesses.it's only upto amd whether we can have unregistered, ddr2 or maybe even xdr memory i guess

"is it possible to have a dual proc setup without using registered memory?"Technically yes...but registered memory is what's preferred for servers because it is more securely accurate. All Opterons use registered memory...
Platforms for the Athlon MP use non-registered memory, and a very few of the Xeon platforms do as well...
