Intel Xeon 5570: Smashing SAP records.

[justapost]

If you look closer at the two benchmark tests, you'll find the slower one has a response time of ~1s, while the other has a response time of ~2s. This is what Micheal S of Realwordtech forums says about these tests:

Thanks for the details. So those benchmarks with the low thruput where intentionally optimized for fast response times. Not so unrealistic if workload are people whom have to feed the SAP system with data thru dialog input.

I got 2 5500 series systems. One 3.2Ghz high performance and one 2.26Ghz low voltage (With turbomode). They both use less. And they are compared directly with the previous counter parts from the same OEM. (LV 5400 was 2.33Ghz tho).

Its both due to FB-DIMMs but also chipset. And in performance they are simply a monster. So more or less twice the computational power and alittle lower power consumption. Its regular 1.5V DDR3. Not lowpower 1.35V. They didnt have them yet.

2.26GHz low voltage version would be an option here. You mean lower in idle?
Performance is not that much an issue, response time is more important.

And remember your servers fanspeed can easily cheat due to temperature in the serverroom. They are always overcooling. And noise is different between OEMs. HP servers tend to make alot mroe noise at the same temperature than Dell etc. But ye, if needed the fans can go between 11500 and 14000rpm.

I'm more concerned about cooling. I expect it is more efficient to avoid heat in above scenario.
