Data Warehouse Test
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 were 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 were 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.

Sounds like computing could change a lot in the next 6 months.I can't wait to get my hands on a dual core chip - that type of multitasking gaming performance is what I've been waiting for... 92% of unfettered performance during Doom3? That's unbelievable.

Another thing to consider is that the 939, and 940 Dual Cores work with old mobos. so that saves upgraders ~$100 for the mobo (I have no clue what PD mobo's are going to cost) plus the cost of DDR2 ~$100 for 512MB, not true if you're going with the PD. So if you own a 939 a 2.8 PD will realy cost you ~$441, 3.0 -$516, 3.2 ~$730.Throw that out the window if you're starting from scratch however.

Great review very detailed, I have one caveat, and I should preface it with the fact that I own 4 systems, and all of them have Athlon 64's or XP's.That being said your "Multitasking Scenario 2: File Compression" Seems to be misleading, and identifies the A64 as the processor of choice in the 2nd portion of the analysis.
Maybe I'm wrong but from what I understand with how the test was performed you archived the file, got the amount of time it took to archive the file "x" for instance, and then figured out how many emails got imported in time "x" now because some processors took longer to create the archive than others they had more time to import emails. so in order to make this data more reflective of the performance of each processor you need to divide the number of emails imported by "x", and get e/s. The modified graph should be
PD 3.2 =19124/5.08 or 3764.57 e/s
A64 X2 =21687/6.25 or 3469.92 e/s
PEE 3.2 =16875/6.65 or 2537.59 e/s
AFX 55 = 3800/5.88 or 646.26 e/s
These corrected numbers show that at least in this test the PD 3.2 is the winner by ~8%

At that prices, most of the users really won't need their current mainboards for new dual core processors. I would prefer to have lower priced single core than that prices on dual core.blckgrffn - Thursday, April 21, 2005 - link
We are talking about by this fall, folks. And a 90nm Dual core still uses LESS die than 2 2800+ put together because it is on a manufacturing smaller process, especially if they stick to a 512k cache which is obviously the sweet spot. By this fall I expect that we will see sub $200 dual cores from Intel to squeeze AMD on the desktop market. What is a real shame is that AMD doesn't have suffcient fabs to handle potential demand.For those of you who got all hot in your pants and said I can't buy a sub $200 dual core Intel right now, it is just as true that I can't buy one it all! ;P Chill!

Am I mistaken in thinking that AMD was throwing out their desktop dualcore line (A64 X2) in 2006? What prompted their earlier release of them? Was it the demand for desktop dualcore, pressure from Intel stealing desktop dualcore market, or excellent manufacturing at the AMD plants?KeithDust2000 - Thursday, April 21, 2005 - link
blckgrffn, "so if they can't bring anything out under $200 I will probably have to go with Intel. Boo for that ;) "INTEL doesn´t have one under $200 either.

#14... all socket 939 motherboards will support the X2 with a BIOS upgdate.Zebo - Thursday, April 21, 2005 - link
#9 They'd have to release a 1.6 @ $240 to accurately compete with Intels slowness in Pentium D's starting at $241. Sorry not gonna happen. AMD not for budget shoppers anymore but those interested in performance. Want the best? Pay the price. Or substandard CPU at a discount?I can see a 1.8 for about $250 though however no way you're going to get into DC for less than $200.
