AMD's 3rd Gen Threadripper processors use the new Zen 2 microarchitecture, bringing substantial improvements over the previous models in this family. The Threadripper line already featured very high core counts, and combined with massively better per-core performance, these are very powerful high-end desktop (HEDT) CPUs.
Here is a table showing the core specifications of the two processors in this generation:
Threadripper 3960X | Threadripper 3970X | |
Cores / Threads | 24 / 48 | 32 / 64 |
Base Clock Speed | 3.8 GHz | 3.7 GHz |
Max Boost Clock | 4.5 GHz | 4.5 GHz |
L1 / L2 / L3 Cache | 2.25 / 12 / 128 MB | 3 / 16 / 128 MB |
MSRP | $1299 | $1999 |
