An assistant to help you compare server CPUs and develop a more informed future state environment using industry standard benchmarks

News Oct 21 2019: CPU2017 Integer Rates have been added for all Intel Skylakes, some EPYC2s (finally have data...), and all Broadwells that have data (not many)

Frequently Asked Questions:
What is SPECint_rate2006 and/or CPU2017 Integer Rates?
SPECint_rate2006 and CPU2017 Integer Rate are a standard benchmark to allow for the comparison of different CPUs and their performance levels with minimal reliance on RAM, storage and other hardware components.
"SPEC" is the non-profit Standard Performance Evaluation Corporation group that has been around since the 1980's.
"Int" means it is integer based math, which is typically representative of most datacenter and user workloads outside of 3D modeling, science or resarch groups.
"Rate" is for the test suite that gets results based on the total performance of the entire system with heavy reliance on CPU and little reliance on RAM, storage, etc.
"2006" or "2017" is the suite version of the tool. Both 2006 and 2017 are shown if the data is available. Please note the 2006 and 2017 versions are not comparable or relatable as they are totally different metrics.

What do all these numbers mean?
See first question for a brief on SPECint_rate. When you compare CPUs, the bigger the SPECint_rate the more work the processor or system can do in the same amount of time. This tool provides SPECint_rate2006 and CPU2017 Integer Rates in several different ways:
Why should I care?
Just because your brand new CPU runs at 3GHz or 22 cores does not mean it is the best one for the job. There are older CPUs that can have higher rates than newer ones. For example, the Intel Skylake Xeon Gold 6136 3.0GHz (SPECint_rate2006 of 1506) and the Intel Broadwell Xeon E5-2698 v4 2.2GHz (SPECint_rate2006 of 1595) which is about 5% better on a dual socket system. It can do that because it has 8 more cores. Though if you look at the SPECint_rate2006 per core it is roughly 36% worse than the Skylake, so depending on your application the Skylake may be better. Or the Broadwell could be better if your application is highly threaded and written correctly. Financial engineering may also impact your design, which is why the tool allows you to compare $Dollar per SPECint_rate. Use this tool to compare processors to assist in your design process.

Why should I trust your tool?
You don't have to. Please go to https://www.spec.org/ and do all this manually yourself. I receive zero compensation, zero ad revenue, zero donations and will not request any (except for Skittles). I do receive a bill at the end of the month for bandwidth and hosting, so it costs me money to help you, which I will gladly do if it helps you and your customers get a better solution and help fight uninformed or just plain bad (lazy) engineers and architects.

I can't find my CPU!?
CPUs are listed with Intel first then AMD. They are then sorted by generation, with oldest first. Then alphabetically, with A first. If you can't find it I may not have added it, so shoot me a note and I can add it to the list no problemo.

Ok really, why?
Fight the FUD and fight ignorance. Knowledge is power and it is your choice to pick up the sword and shield. If you don't, hopefully someone else will.

How can I help?
