I'd rather choose really big caches per core than really big number of cores.

I'd rather choose really big caches per core than really big number of cores.
- kllrnohj 7y agoZen2 is 16MB L3 per ccx across the entire stack (hence why even the Ryzen 5 3600 is 32MB of L3 - it has 2 CCXs). There's no reason to assume this won't be true on Threadripper 3000. So a 32-core Threadripper 3000 would have at least 128MB of L3.
- qwerty456127 7y agoL2 cache is what matters. Zen2 has just 512 KiB per core. My old Pentium-M had 2MB. I wish modern CPUs had at least this much.
- kllrnohj 7y agoPerformance is what matters, not cache size. Your Pentium-M didn't even have L3, hence why its L2 is so big.
