So one cool thing about the new Zen 3 cpus are the fact that 5600x and 5800x now have a lower inter-core latency than Intel's own monolithic design. Now this does technically apply to the 5900x and 5950x as well but because those have CCD to CCD latency, it does make them slightly worse in that department for applications that actually require the cores to communicate between each other that use above 6 for 5900x and above 8 for 5950x.
"Inter-core latencies within the L3 lie in at 15-19ns, depending on the core pair."
"Inter-core latencies between cores in different CCDs still incurs a larger latency penalty of 79-80ns, which is somewhat to be expected as the new Ryzen 5000 parts don’t change the IOD design compared to the predecessor, and traffic would still have to go through the infinity fabric on it."
"For workloads which are synchronisation heavy and are multi-threaded up to 8 primary threads, this is a great win for the new Zen3 CCD and L3 design. AMD’s new L3 complex in fact now offers better inter-core latencies and a flatter topology than Intel’s ring-based consumer designs, with SKUs such as the 10900K varying between 16.5-23ns inter-core latency. AMD still has a way to go to reduce inter-CCD latency, but maybe that something to address in the next generation design."
Intel really is getting killed in more ways than one this generation!
