One idea springs to mind: look out for bargains on x670e boards if you find one that has all the features you need. x870e is literally the same chipset, just with an added asmedia usb4 controller. If you don’t care about usb4, or you find a bargain on an older board with the Intel usb4 controller, you might as well get that one.
96GB ram is running well on my AM5 system (at 6200 MT, could not get 6400 MT stable even though the sticks are rated for that; but zen 5 should have a better IMC that can handle higher speeds).
Otherwise you can start speccing out a system and order when parts are available. There should not be many surprises, and all AM5 boards have a bios flashback USB port that can be used to update the bios without needing a CPU installed, so that is one worry less.
Seems like the max clocks of zen 5 are the same, but IPC is up 20% and multithreaded clocks should be better thanks to improved efficiency.
So having watched most of the 9000 series CPU reviews, including Wendell’s, I’ve come to the conclusion that I may not really need any of these CPU’s currently and so I’m contemplating the following move.
Purchasing a new mobo + 7800 X3D CPU for my gaming rig.
I will probably get another NVMe SSD to install a fresh Windows 11 OS onto.
I will then take my 7950X cpu and mobo and install 96GB of RAM using a pair of 48GB modules and update my older Threadripper 2950X machine.
I found I really didn’t ever need all those I/O lanes and an X670-E mobo should be just fine for my needs.
Also running DDR5 at say 4800/5200 should be fine for my Workstation needs.
Probably look into getting another GPU but will test my older Radeon VII to confirm if I need to update it or not.
