It's a benchmark of the game and I use it for exactly that purpose, as a benchmark because it shows extremely well how the frames jump up and down and if there's a latency issue, it visualizes very well.
Yes, it works similar to CapFrameX and shows similar graphs.
In Metro Exodus, the benchmark...
Yeah, it depends on the game, and most games are like that, okay.
7900x is significantly worse in Metro Last Light 20++ avg less and 0.1% is crap. It seems to work "flawlessly" but all the graphics are bad.
So you can find games that will have the dual CCD problem and it's a communication issue...
Very easy for me, at moment I have 7700x@6200 RAM and 7900x@6600 RAM, both tuned.
The 7900x is most of the times few or some avg FPS below 7700x, but 7900x can be better at 0.1% low FPS.
Same apply at x3D variants and you can see it at TPU reviews (or anywhere), this is because Infinity Fabric...
The Infinity Fabric can't handle it, the transfer would be really huge if it needed to transfer AND the cache from the 3D cache through it for the transferred thread.
Maybe next gen if there are at all CPUs like the current 79X0x3D (CCD+3Dcash CCD).
Of course it takes time :), as with any overclock.
250w is too little, need more and it's all about which system will run 0.5-2% faster :D
I've also been using AMD for a long time and yes, I agree that nowadays AMD are closer to "just works" than Intel.
I understand your choice and it is a good one, the 7950X3D is a very nice processor that you can just plug and play. That's what made AMD jump up.
But to say the 13900k is crap because you can't stabilize its clock speed/heat and you can't stabilize its RAM is just a lack of skill. Yes, I know...
If we talk about Sapphire NITRO+ RX 7900 XTX Vapor-X it has the highest TDP than other models, so it is supposed to clock higher and to be a little faster.
