They are bunched close together cause the run is GPU bound. Mine isn't, im using DLSS.I'm pretty sure that making general statements based on a game or two is not normal.
As I've shown, the CPUs are all stacked close to each other in TLOU, what exactly is your point? We are measuring differences of 5FPS in this title and we need to have a huge discussion on how because of this title every other game benchmark is not needed anymore?
I can play the "in this title" comment game too. can your tweaked 12900k beat the stock 7800x3D in: A Plague Tale: Requiem, Hogwarts Legacy, Baldur's Gate 3, Star Wars Jedi: Survivor, Assetto Corsa Competizione, Assassin's Creed Mirage, Watch Dogs: Legion?
Regarding your second paragraph, that's exactly what im testing right now. Me and my friends have gathered a 5800x 3d, a 7800x 3d, a 12900k and a 14700k and testing. Up to this point the 5800x 3d seems completely out of the competition, we measured up to 40% differences compared to my stock 12900k. Eg. Ratchet. I can give you the video
The only game it wins to this point by around 12% is Flight simulator.
