Has AMD lost their mind with the 7950X3D?

[THE LORD]

With MB included, it's many hundreds of $$$ more than the 13900K.

And how much is the performance gain in the 7950X3D over the 13900K?

Overall concurred with your post, however, it isn't that they aren't "required". It would still park those cores while running an identified gaming workload even if those cores were "required".

Reviving an old thread here but I wanted to clarify this since I went ahead and picked up a 7950X3D and have done a little testing against the 7950X. While the second ccd is "parked" during gaming it is not unusable. If your workload exceeds the v-cache ccd the second ccd will go to work, its automatic and the default behavior. I had to run background tasks to get enough load for it to occur, I haven't found a game that exceeds the 8 cores. If anyone knows of a specific game I can test let me know, do keep in mind though that while some games appear to be using more than 8 cores its likely the processes are just core hopping, its hard to pick up just watching task manager because it happens so quickly. I suspect that if a game did exceed the 8 cores it would utilize the second ccd but I just haven't been able to confirm it.

I'm also messing with Process Lasso. I think its a much better solution than Game Bar if you don't mind being a little hands on. If you want a simple configuration you can set Steam to the v-cache ccd and all games launched through Steam will default there and then set all of your other tasks to run on the second ccd (aside from a couple of Windows processes that can not be assigned or moved). The other option and better one in my opinion would be to launch the games tied to the v-cache ccd and use the overlay of your choice to monitor performance, then tab out and switch to the other ccd and monitor again. Once you know which works best, set it and forget it. It only takes a minute and it ensures you are getting the best performance rather than just defaulting even though that probably is the correct choice 90% of the time.

I plan to do a lot more testing but right now I cant get accurate numbers because of an Asus bios issue. If I run 0805 I don't have the optimizations for the 3D processors and 0922 introduced some memory compatibility issues and I'm not able to enable DOCP.
