EPYC 7742 64-Core Processor Cache Bandwith


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 AMD EPYC 7742 64-core 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.
