Wasn't the server part of Zen with 64MB L3? 80MB total with L2. (Rumored of course). That's massive.

Each CPU cluster will be comprised of 4 "Zen" cores with dedicated 512 KB level 2 caches, and 8 MB level 3 cache, shared between the cores. In maximum configuration, an 8-cluster microprocessor will come with 16 MB of L2 cache and 64 MB of L3 cache. Each core will support some form of simultaneous multithreading and will run two threads in parallel.

Doesn't change the fact that they'll be packaged together. I prefer this. It's efficient and affordable.

Good lord. That has to be dual-die. Haswell-EP and EX are 18 cores and 662mm^2 dies. 14 more is going to be huge, even on a smaller node. Plus, AMD tends to make the fewest dies possible - Vishera goes down to two modules or up to 2x4 modules.

Haswell-EP (not sure about EX) also has up to 45MiB L3 and a combined total of 4608KiB L2 or another 4.5MiB for 49.5MiB total. That's ridiculous if AMD is going up to 80MiB (though they always have had more L2 than Intel, especially the APUs since they lack L3).

That's great for power efficiency though, since having slightly more cache usually impoves performance per watt even though it reduces performance per mm^2. That's only up to a certain point since going past certain amounts is usually a total waste, but 256MB L2 and 2MB of L3 is realistic and makes sense in a modern high IPC arch, if the caches themselves are designed properly.

80MB is massive, but for two dies at 14nm it doesn't sound odd. The L2 on Piledriver chips was simply massive both in size and die are and the L3 wasn't dense enough. Even without improving the density they could probably get away with 40MB L2+L3 on a single die, including the integrated NB+SB, without ending with a chip much larger than Vishera simply due to the node.
