Frequently Asked Questions:
What is SPECint_rate2006?
SPECint_rate2006 measures the total CPU performance of a multi-core system using a standard benchmark to allow for the comparison of different CPUs and their performance levels.
"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" is the suite version (they have 2000, 2016, etc) but this version was selected as it allows us to compare the last several generations with current generation CPU families.

What do all these numbers mean?
See first question for a brief on SPECint_rate2006. When you compare CPUs, the bigger the SPECint_rate2006 the more work the processor or system can do in the same amount of time. This tool provides SPECint_rate2006 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 Xeon Gold 6136 3.0GHz (SPECint_rate2006 of 1506) and the Intel 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_rate2006. 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. 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!?
They are currently 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?
Use the tool, spread the word, email me any feedback (except about spellcheck).
