Data Warehouse Results
This test is different than our other tests as there are no parallel queries being executed. On the other hand, the query optimizer is able to use parallel execution and utilize multiple processors for the same query. This does not lead to the same CPU load as parallel queries, but does demonstrate a measurable difference in execution time.In these tests, the datasets are mostly 100,000+ records and are many times larger than the L2 and L3 cache; thus, the additional cache is of no benefit. It is all about the number of instructions that can be completed in a given period. The ability to move data quickly in and out of the CPU are the characteristics of a winner in this test.
- There is a 30% spread in results between the fastest and slowest platform. Yet again, it is proof that you do not have to be CPU bound to recognize a performance gain from a hardware upgrade.
- The Dual Opteron 252's lead by 19% over the closest Xeon, which was the Quad Xeon 3.6 GHz 667MHz FSB
- The Quad Xeon 3.6 GHz 667MHz outperformed the Dual 3.6GHz 800MHz FSB by 8%.

page 3 "For example, the Opteron 252 and Opteron 852 both run at 2.6GHz, but the 252 is for use in up to 2-way configurations, while the 852 is certified for use in 4- and 8-way configurations. The two chips are identical; it's just that one has been run through additional validation and costs a lot more. "I thought that they had different number of HyperTransport (HT) links:
152 - 1 HT
252 - 2 HT
852 - 3 HT
I thought that was the reason why it was impossible to use two 152s in a two-way motherboard.
Maybe i'm wrong.

#50Dual 875s have 4 cores

I have waited SOOOOO long! Finally, a reason to dump my dual PIII setups. Next stop, Athlon64 X2!jediknight - Thursday, April 21, 2005 - link
Can someone explain the huge performance difference between the dual Operaon 252s (2.6GHz) and the dual Opteron 875 (2.2GHz)?Since:
"The two chips are identical; it's just that one has been run through additional validation and costs a lot more"
I would expect the 252s, running at 400MHz more, would outperform the 875s. Can someone explain this (large) discrepency?

Yes. That's gonna be a four proc-machine. Terrific.I am really astonished about whole AMD K8 architecture. And K9 should be 4-core processor architecture.
Can't wait.
But, I still won't get a rid of my AX2600 machine.

Ah the brilliant KillerBob.Anand used plenty of real world apps for the multitask benchmarks.
How much more real world testing would you want to go with your (pointless) whining?

Why is their stock price at a 6 month low? I hope this pulls it up a bit. It would be a shame if they don’t start making a profit.suryad - Thursday, April 21, 2005 - link
I just am astounded at the performance these first versions of dual core processing that is being presented to us...WOW...couple that with a well written 64 bit OS and it will be even more smoking!! I think AMD did a job extremely well done and I am glad that they are being aggressive in keeping their pockets full with the prices of their chips. I personally dont think that would stop me from buying their processors. I would wait for the FX to become dual core though. A 3 ghz dual core FX would rock so bad!!!Also one more thing...so the Tyan mobo holds 2 procs correct? So if we stuck a dual core in 1 socket and another in the other sock...that makes it a 4 proc machine then right?!!

Thanks for the double post KillerBob. Your statements are as intelligent as your ability to use a keyboard.
