So it's permanently ON by design and can't be turned OFF? Phoronix ran a few test with OFF but it was done thru the Linux Kernel so not by the BIOS and instead of low power consumption it increase it because the CPU is doing more work. I wanted to see if any of you lucky ones that have the $$$ to upgrade if you could search on the BIOS and see if it could be disabled.AMD has no such plan to disable avx-512.

If it's possible to disable a whole CCD, it would be more stable? Could be beneficial for games as most don't need 32 threads.On a different note, I got it to post and test aida at 6400/2067 FCLK. Probably not stable yet but numbers keep looking better and better.
Yes, the best gaming processor would be a 7950X with the weak CCD disabled and only the Strong CCD enabled, I have seen how the 7700X and 7600X have great gaming performance and many times besting the 7950X, knowing that the 7950X has the best binned CCD would put it at an advantage for boosting.If it's possible to disable a whole CCD, it would be more stable?

There is a per core enable/disable bit field for each CCD - it appears you must match the core count in both CCD's (both have 5 enabled, etc, but it can be any 5 cores in each CCD) but I tested it in a CCD disabled state with every core disabled in one CCD and that worked as well.
I did try asymmetrical core counts (5 in CCD0 and 3 in CCD1) and it didn't like that at all.
There is no straightforward "CCD DIsable" setting like I have seen on X570.
He was talking about X670E.You are incorrect. I can disable the CCDs in the BIOS on both of my X570 boards. Automatic, CCD0 Disabled, CCD1 Disabled.
He was talking about X670E.
[Notice of postponement of release]
Scheduled to be released on October 11, 2022
(Monday)
Motherboard with B650 chipset "PRO B650-P WIFI"
Release due to various circumstances It has been postponed until Friday, October 14, 2022.
Maybe wait for 7800X3D?
Im going to ask a dumb question but ......
looking at the B650e and x670e motherboards.....
Why would I buy the x670e's?
The Aorus B650e master seems to be just a competent as the x670e master for much less cost. (350$ vs 500$)
The advantages really seem to be 1 extra PCIe 5.0 M2, (not chipset related) better audio, better network, few extra USB ports.
B650 vs X670 (and E variants) was always going to be differentiated primarily through IO expansion. If you don't need the extra IO, just get a B650(E) mobo.Im going to ask a dumb question but ......

If price is same, go for the X670E.I was looking at the ASRock X670E PG lightning for $245 and the B650E Riptide PG for $240.
Doesn't have Wi-Fi built in.If price is same, go for the X670E.

Well, I don't know what the VRM's deliver, I have not evaluated it. I chose the 670E for the 24+2+1 vrm's on my motherboard.Yeah I have seen the charts, but I was wondering if there were any other differences anyone has seen.

It was $500. But until I got it I had no idea. After I get things ironed out, I will probably set it to 170 and be good with it.Yeah I am watching the power stage makeups, but you must have got some expensive board(s) to get the 24+2+1.
At the preferable 250-350$ price range most of them look to be 14+2 or 16+2. I'm not likely to get the 7950, maybe 7900 likely the 7700.
It looks like the PCIE slot is WAY at the bottom, and your case would have to be at least 2 slots longer than this to put a decent video card in.

It looks like its only useful for someone using the internal video card on the CPU (the IGP)
