SAP S&D 2-Tier
| SAP S&D 2-Tier | |
| Operating System | Windows 2008 Enterprise Edition |
| Software | SAP ERP 6.0 Enhancement package 4 |
| Benchmark software | Industry Standard benchmark version 2009 |
| Typical error margin | Very low |
The SAP SD (sales and distribution, 2-tier internet configuration) benchmark is an interesting benchmark as it is a real world client-server application. We decided to take a look at SAP's benchmark database. The results below all run on Windows 2003 Enterprise Edition and MS SQL Server 2005 database (both 64-bit). Every 2-tier Sales & Distribution benchmark was performed with SAP's latest ERP 6 enhancement package 4. These results are NOT comparable with any benchmark performed before 2009. The new 2009 version of the benchmark produces scores that are 25% lower. We analyzed the SAP Benchmark in-depth in one of our earlier articles. The profile of the benchmark has remained the same:
- Very parallel resulting in excellent scaling
- Low to medium IPC, mostly due to "branchy" code
- Somewhat limited by memory bandwidth
- Likes large caches (memory latency!)
- Very sensitive to sync ("cache coherency") latency
(*) Estimate
The last time we discussed the SAP S&D 2-tier benchmark, we had to estimate the Xeon X5670 results. Since then HP has benchmarked its latest G6 servers, giving us results for the X5670. The performance is nothing short of astonishing. The dual Xeon X5670 outperforms a quad Opteron 8345 at 2.6 GHz. The Magny-Cours Opteron can only compete based on its somewhat lower price. We doubt that the SAP buyers care about a few hundred dollars though. A quad Opteron 6174 might have a chance against the Nehalem EX performance wise, but the SAP market will probably prefer the extensive RAS list of the Xeon Nehalem EX. The ERP market is most likely going to be dominated by Intel based servers.

It should be noted that newer nehelam based processors have specific AES encryption instructions. The benchmark where the xeon blows everything out of the water is likely utilizing that instruction set (though, AFAIK not many real-world applications do)Hector1 - Tuesday, March 30, 2010 - link
I read that Intel is expected to launch the 8-core Nehalem EX today. It'll be interesting to compare it against the 12-core Magny Cours. Both are on a 45nm process.spoman - Tuesday, March 30, 2010 - link
You stated "... that kind of bandwidth is not attainable, not even in theory because the next link in the chain, the Northbridge ...".How does the Northbridge affect memory BW if the memory is connected directly to the processor?

Depending on your definition, the nortbridge is in the CPU. AMD uses "northbride" in its own slides to refer to the part where the memory controller etc. resides.Pari_Rajaram - Tuesday, March 30, 2010 - link
Why don't you add STREAM and LINPACK to your benchmark suites? These are very important benchmarks for HPC.JohanAnandtech - Wednesday, March 31, 2010 - link
Stream... in the review.piooreq - Wednesday, March 31, 2010 - link
Hi Johan,For last few days I did several tests with Swingbench CC with similar database configuration but I achieved a bit different results, I’m just wondering what exactly settings you put for CC test itself. I mean about when you generate schema and data for that test? Thanks for answer.

Your question is not completely clear to me. What is the info you would like? You can e-mail if you like at johanATthiswebsitePointcomzarjad - Wednesday, March 31, 2010 - link
Can't figure out if hyperthreading were enabled on Intels. Particularly interested in virtualization benchmark with hyperthreading both enabled and disabled. Also of interest would be an Office benchmark with a bunch of small VMs (1.5 to 2GB) to simulate VDI configuration.JohanAnandtech - Thursday, April 1, 2010 - link
Hyperthreading is always on. But we will follow up on that. A VDI based hypervisor tests is however not immediately on the horizon. The people of the VRC project might do that though. Google on the VRC project.
