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.

1. Why is the TDP of the 65W ACP Magny Cours the question mark? And are you sure the TDP of the 80W ACP ones 115W?2. The Intel systems have only 24GB ram against the 32GB ram on the 2S magny cours. That's why the 100GB database test favors the Magny cours by a large margin.

AMD told us the TDP values of the Magny-Cours at 80 and 105W ACP. The TDP values of the Lower power versions were not disclosed yet.And as we disclosed on the benchmark config page, none of the benches uses more than 20 GB. The vAPus mark I uses about 19 GB. The SQL Server uses much less. While the SQL server test has to scan through the complete index, it does access the complete 100 GB data. There absolutely no advantage for the Opterons there. We checked.
The fact that we spec the servers like that is a direct consequence of their memory channels (3 and 4). There is not much we can do about that.

How about about 4P performance? It's cheap now and it's AMD whole selling point. I guess you can get a 4P 48-core 128GB system for not that much. How would that compare to a say 2P Nehalem 12-core 92GB? Wouldn't they cost about the same? Will it still be competitive against 8-core 2P Nehalem-EX? And how about the 4P (like 6-core versions) Nehalem-EX? How about the 8-core versions of 6100 series Opterons?elnexus - Wednesday, March 31, 2010 - link
In answer to cost:Compare our 2P Xeon 5600-series Workstation :http://elnexus.com/products.aspx?line_id=15514
with our 4P Opteron 6100-series Workstation: http://elnexus.com/products.aspx?line_id=15635
(I hope this isn't condemned as advertising, since it is an attempt to answer a question about price vs performance.)
Note how low priced the 6128 chip is (the default chip included in the base price).
AMD, I think are running away from Intel if you factor in the price...

Thanks, I don't condemn it as advertising as this is a new platform so it's interesting and hard to get prices for complete systems yet. Basically 4P 8-core 6100-series opterons with 128GB DDR3 ECC REG cost as much as 2P six-core Xeon (Westmere EP) with 96GB DDR3 ECC REG. Mainly because you can use cheaper 4GB sticks and still get 128GB. And partly because there's no longer any markup for above >2P parts. I guess it accounts for something. Yeah, 6128 chip virtually don't cost nothing for being 4P compatible. Guess it helps AMD for a lot of workload scenarios. And since you can get 4P in 1U it's really nothing that speaks against it. Will be interesting to see what the Nehalem-EX can do though.TitanusComp - Wednesday, April 6, 2011 - link
You can really get a good idea by comparing this two products:48 Cores:

24 Cores (Quad SLi Capable)
http://www.titanuscomputers.com/X450-Intel-High-Pe...
Now, things to consider, do you need CPU or GPU power?

To make the whole benchmark complete I think you should ask some AMD Opteron 6136 from AMD to get a full review.duploxxx - Monday, March 29, 2010 - link
and add the 56xx 4core counterpart off courseJohanAnandtech - Tuesday, March 30, 2010 - link
We are working on it. Expect an update with new SKUs this month. I would say next week, but I would like to take some time to do some in depth analysis.Hacp - Monday, March 29, 2010 - link
Anand,I want to ask why are you biased against AMD? You should base your tests based on price. AMD is selling their 12 core for the price of an Intel 6 core. Compare apples to apples! Do a 12 core vs 6 core comparison and see who wins. Otherwise, you are doing a disservice.
