Epyc has more PCIe lanes and all of them are octa-channel RAM while only some of the threadrippers are. Also you're limited to only 1 Threadripper per motherboard.
I think I saw a rumor somewhere that there would be a 64/128 Threadripper. Any idea when?
Also, I saw that Intel would be announcing new HETD CPUs later this month. Any rumors on what they will be announcing?
There will be a 96t and 128t but I don't know when they will be available.
January
It's a long story but what Intel is about to launch is a joke. If you got a 9980XE, then you already have the new 10980XE. There are no improvements with the exception of 4 additional PCIe lanes, but if you don't buy a new motherboard, you can't use these extra lanes because the wiring doesn't exist. So far, I've seen 2 leaked benches where a mainstream Ryzen 3950X beats the 18 core 10980XE HEDT. I honestly can't tell that Intel is even trying anymore.
