"Going to be"? The Ryzen 3600 ($199) and above already have 32MB L3 cache, the 3900X ($499) and above already have 64MB. The big L3 cache is already a big selling point of Zen 2.
- cma 6y agoThe difference they talked about is it is now uniform latency instead of split into two blocks of 16MB accessible at different latencies depending on which group of four cores you are on.
- sbierwagen 6y ago3990X has 256mb of L3.
- bcrl 6y agoBut only 16MB of L3 is accessible to each core in Zen 2 - no single core can utilize all 256MB of L3 cache. That's why Zen 3 cores being able to access the full 32MB of L3 cache that's on die is a big deal.
- ShinTakuya 6y agoYeah but it's not as relevant to the discussion given it's in a different class of CPU not really aimed at average consumers. It's fair to mention it, though.
