Hardware AMD Ryzen ThreadRipper 3990X 64 Cpu Cores 128 Threads !

AMD is on a roll lately with their AMD Ryzen Zen2 and AMD Rome Zen2 processors. Leaks are out of their new AMD Ryzen ThreadRipper 3990X with 64 cpu cores and 128 cpu threads AMD Ryzen Threadripper 3990X 64 Core & 128 Thread CPU Leaks Out !

Yesterday, AMD officially unveiled its 3rd Generation Ryzen Threadripper CPU lineup, featuring up to 32 cores and 64 threads on the new sTRX4 socket-based TRX40 platform. While the initial lineup is planned for launch on the 25th of November, there's one part that wasn't included or teased as planned and that part is the flagship Ryzen Threadripper 3990X.

MSI posted their TRX40 Creator motherboard introductory video yesterday and in that video, MSI leaked out the 64 core and 128 thread chip. The video which has now been taken down by MSI showed the TRX40 Creator and a Threadripper CPU performing some intensive workloads but MSI decided to open the task manager for us too.

In the task manager, we can spot 8 vertical and 16 horizontal tiles. This rounds up to a total of 128 threads. For comparison, the Ryzen Threadripper 3970X features 64 threads and the TRX40 creator doesn't feature two sockets so it is definitely a single chip that features 128 threads. There is also no possibility that this could just be the 2nd Generation EPYC chip as those are designed around the server platform and there have been failed attempts before to booth EPYC chips on the HEDT X399 platform. So this is definitely a very early sample of what is supposed to be AMD's flagship Threadripper, the 3990X.

AMD Ryzen ThreadRippers

To put this into perspective, highest core count Intel Desktop cpu right now is Intel Core i9 10980XE and Intel Core i9 9980XE with 18 cpu cores and 36 cpu threads which have respective RRP of $1000 and $1999.

And highest Intel Xeon core count is Intel Xeon 9282 Platinum Scalable cpu with 56 cpu cores and 112 cpu threads but has a price tag rumoured to be between $25K to $50K but it's apparently 84% faster than AMD EPYC 7742 64C/128T cpu in HPC AI Performance Benchmark Suite.

The Xeon Platinum is one of the elusive Cascade Lake-AP processors which feature two dies instead of a single monolithic one, stacking up to 56 cores and 112 threads. The chip has a base clock of 2.60 GHz and a boost clock of 3.80 GHz along with 77 MB of cache and a TDP of 400W. The Intel Cascade Lake-AP chips feature 12 memory channels compared to AMD's 8 memory channels per chip.

The AMD EPYC 7742 is based on a 7nm process node (vs Intel's 14nm+++) and features 64 cores / 128 threads. The chip has a base clock of 2.25 GHz and a boost clock of 3.4 GHz with 256 MB of L3 cache, 128 PCIe Gen 4 lanes and a TDP of 225W. The pricing plays a huge role too and here we see the EPYC 7742 with a price of $6950 US while the Xeon Platinum 9282 is suggested to have a price between $25K - $50K (via Anandtech).
