SAP S&D
The SAP S&D 2-Tier benchmark has always been one of my favorites. This is probably the most real world benchmark of all the server benchmarks done by the vendors. It is a full-blown application living on top of a heavy relational database. And don't forget that SAP is one of the most successful software companies out there, the market leader of Enterprise Resource Planning.
We analyzed the SAP Benchmark in-depth in one of our earlier articles:
- 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
Let us see how the new Xeon E5 fares in this ERP benchmark.
(est) = Preliminary data
The ever-increasing L3 cache, high core counts, and better NUMA coherency support of Broadwell-EP play well with SAP. It is almost like Intel builds these Xeons for SAP alone. The result is that the current Xeon is no less than 3 times faster than the Xeon 2690 (v1).

Does anyone know the Windows support situation for Broadwell-EP for workstation use? Microsoft said Broadwell is the last fully supported processor for Windows 7/8.1 with Skylake getting transitional support and Kaby Lake will not be supported. So how does Broadwell-EP fit in? Is it lumped in with Broadwell and is fully supported or will it be treated like Skylake with temporary support until 2018 and only critical security updates after that? And following on will Skylake-EP see any Windows 7/8.1 support at all or will it not be supported since it'll presumably be released after Kaby Lake?extide - Friday, April 1, 2016 - link
When MS says they are not supporting Skylake on Windows 7 DOES NOT MEAN it won't work. It just means they are not going to add any specific support for that processor in the older OS's. They are not adding in the speed shift support, essentially.For some reason the press has not made this very clear, and many people are freaking out thinking that there will be a hard break here will stuff will straight up not work. That is not the case.
Broadwell has no new OS level features over Haswell (unlike Skylake with speed shift) so there is nothing special about Broadwell to the OS. As the poster above mentions, they are all x86 cpu's and will all still work with x86 OS's.
The difference here is between "Fully Supported" and Compatible. Skylake and even Kaby Lake will be compatible with WIndows 7/8/8.1.

Johan, this is yet again by far the best Enterprise CPU benchmark that's available anywhere on the net.Thank you for your detailed, scientific and well documented work. Works like this are not easy, I can only imagine how many man hours (weeks?) compiling this article must have taken. I just want you to know that it's hugely appreciated.

Great to read this after weeks of hard work! :-Dfsdjmellisse - Friday, April 1, 2016 - link
hello, i want to buy E5-2630L v4any one can give me website for buy it ?
Best regards

I'm confused by the following:"The following compiler switches were used on icc:
-fast -openmp -parallel
The results are expressed in GB per second. The following compiler switches were used on icc:
-O3 –fopenmp –static"
Shouldn't one of these refer to icc and the other to gcc?
JohanAnandtech - Friday, April 1, 2016 - link
Pretty sure I did not mix them up. "-fast" does not work on gcc neither does -fopenmp work on icc.patrickjp93 - Friday, April 1, 2016 - link
Um, wrong and wrong. -Ofast works with GCC 4.9 and later for sure. And -fopenmp is a valid ICC flag post-ICC 13.JohanAnandtech - Saturday, April 2, 2016 - link
"-fast" is a typical icc flag. (I did not write -"Ofast" that works on gcc 4.8 too)extide - Friday, April 1, 2016 - link
Johan, if you read the comment, you can see that you mention icc for BOTH.
