Intel(R) Xeon(R) Platinum 8360Y CPU @ 2.40GHz Cache Bandwith

[speedport1502]

Hi,

I am currently writing my bachelor thesis on benchmark characterization. For this purpose, I'm profiling certain benchmarks and compare the results with the theoretical peak performance of some systems. One of these systems has two Intel Xeon Platinum 8360Y CPU @ 2.40GHz processors. While the maximum FLOPS and DRAM memory bandwidth can either be easily calculated or is given in the specification, I have not found any information about the maximum bandwidth/throughput of the system's L2 and L3 cache. Is there a viable way to calculate this, or can the information be found somewhere else? 

Thank you in advance for your response.

Hello, speedport1502,

Thank you for reaching Intel Communities. I will gladly help you.

Allow me some time to research and see if I can find the information that you want. Hopefully, another community user might let us know the right answer in the meantime.

Best regards,

Allan

Hello, speedport1502,

Thank you for your patience. You can use the Processor Identification Utility available in the article "How to Find the Size of L1, L2, and L3 Cache in Intel® Processors": https://www.intel.com/content/www/us/en/support/articles/000057727/processors.html

The results will show the maximum cache supported:

The specification about the cache (for this model: 54M) can be found on the Intel® Xeon® Platinum 8360Y Processor Product Specifications: https://ark.intel.com/content/www/us/en/ark/products/212459/intel-xeon-platinum-8360y-processor-54m-cache-2-40-ghz.html

If you want to check the memory latency, you can use Intel® Memory Latency Checker v3.10: https://www.intel.com/content/www/us/en/developer/articles/tool/intelr-memory-latency-checker.html

Best regards,

Allan

Hello Allan_A_Intel,

Thank you for your time and answer.

I will test the tools you sent me and discuss the results with my supervisor. Depending on the outcome, I will mark the question as solved or come back to you.

Kind regards,
