True, but the Threadripper requires the TRX50 platform, so I still don't understand what is operative about the statement that the X870E chipset supports quad channel memory.
Good point. Makes me wonder if they'd consider a Threadripper version that uses that chipset, since the Non-Pro Threadripper have been in a weird spot ever since Ryzen went up to 16 cores. An AM5 Threadripper might not make sense because one of the appeals were the much bigger amount of PCIe lanes, but I wonder if they would pair the X870E with a new socket for Zen 5 Non-Pro Threadrippers.
A Threadripper with 24-32 cores but only 2 channels of memory, that worked in the AM5 socket, would fill a nice hole in the AMD story. I don't know if AM5 has enough power pins to do the job, though. If you want more than 16 cores right now you have to spend $2k on the CPU and motherboard, triple what it costs to get a 16-core Ryzen.
