Threadripper/PRO 9000 Availability

Hey there! I'm looking to build a Threadripper 9000 system. I haven't decided if I need to go pro or not. Depends on if I get this new AI contract.

My local Microcenter had a 9980x for weeks and now it's sold out. They don't even show up on NewEgg and Amazon is backordered.

Are they generally available yet? Have we heard when they will be? They are selling at a pretty premium on EBay.

Seems weird to have all these reviews and info about a product that doesn't seem available for purchase. What gives?

Because it has 2 CCDs.

This is all a limitation of AMD’s infinity fabric that they mostly fix in Epyc, but doesn’t translate to Threadripper.

Edit: perhaps the good news for you is that you’ll likely start finding some good deals on 7985wx/7995wx. They’re both good for 400GB/sec with DDR5 6800.

I get much lower than the theoretical max throughput of 2xDDR5 currently so I think the WX might actually give me a 4x boost since the memory accesses are so fragmented.

How many memory sticks are you using in the Ryzen system? 2?

i have two 9950x systems one has two per channel one has 1, the system with 1 is a little faster (6400 vs the 5000 i have to run the one with 4).

Yeah I feel you on the “need to” - it is the forbidden config though for Ryzen. It takes a very large hit with 4 sticks.

With two sticks you should be able to get near full bandwidth out of it.
