Determining cache sector size for a processor

Question

I'm trying to build tests around processor cache-line optimizations relative to parallel processing. Specifically, I'm testing how segments of my products are being impacted by False Sharing inefficiencies. To do this, I need to be able to determine my processors cache sector size (Ex. 64 bytes) so I can contrive tests with the appropriate object size ranges. So... how or where can I get this information (e.g. processor spec page, C# API call, etc...)? Cache sector size is also known as Cache Line size.

Note: I looked on the Intel site for my i7 processor spec and can't find these details, or maybe I just can't recognize it.

Answer 1

I have done a similar experiment. I use CPUZ and find it extremely helpful with detailed information about CPU cores, caches (L1, L2, etc)...

My suggestion: don't be distracted too much by hardware specs, focus on benchmarking because your experiment is going to take a lot of time.
