A modular approach! Kudos to AMD for making it work nicely (anyone remember the first Pentium Ds, that were just two Pentium 4s clobbered together to make a dual-core chip?).

Apart from that, I think you meant two-and-a-half, not one?

Nope, one-and-a-half! Two of the CPU dies, one interconnect die - that's going to be somewhere between one and two!

And their interconnect tech seems like it's going to be of huge importance in the server space - I can only imagine the yields on 8x4 core modules will be far higher than on a monolithic 32 core chip.

The next EPYC's going to be up to 8 chiplets x 8 cores, competing against Intel's current 28-core monolithic die (or their dual-die non-socketed 56-core). How many cores remain enabled on a hypothetical next-generation Threadripper is an open question, but they would probably go beyond 32 cores total. And a 32-core Threadripper would probably not have 8 chiplets but rather four fully-enabled active chiplets and four mechanical spacers.
