AMD has yet to officially unveil its Zen 3 architecture-based Ryzen Threadripper 5000 CPUs (codenamed Chagall), but some details are already clear from several specimens in the wild, revealed by multiple entries in two benchmark databases.
AMD Ryzen Threadripper
The two new leaked next-gen CPUs are the AMD Ryzen Threadripper Pro 5995WX and Pro 5945WX, both aimed at high-end workstations. The top model is the Pro 5995WX will replace the current Threadripper Pro 3995WX (with 64 cores) and has 64 CPU cores (128 threads) and probably 256 MB of cache, the Pro 5945WX only has 12 (24 threads). Most likely, AMD&s Ryzen Threadripper Pro 5000WX family will include even more models, probably a 16-core (32-thread) version as well as a 32-core (with 64 threads) version.

The Twitter channel 
Benchleaks reported entries in the benchmarks from Milyway@Home, PugetBench Metashape (which has been deleted in the meantime, though). In the latter, the AMD Ryzen Threadripper Pro 5995WX on an AMD Sharkstooth-CGL motherboard with 64 GB of 3,200 MHz RAM and an Nvidia GeForce RTX 3080 achieves a time of 8601 seconds in the Park Map benchmark and 2,250 seconds in the School Model benchmark (smaller is better) - in both tests, the new Zen 3 model is around 20% faster than the predecessor Threadripper 3995WX Pro with the Zen 2 architecture.

Most likely, the Pro 5995WX will support 128 PCIe 4.0 lanes directly connected to the CPU and up to 2TB of DDR4 RAM - the TDP could be 280W according to a leak from motherboard manufacturer Gigabyte. The official announcement of all new Threadripper 5000 consumer models is rumored to happen in the fourth quarter, and the Threadripper Pro models, which are exclusively for workstations, will be announced early next year.
