Did you watch the reviews? It looks like games will be caped to 8 cores and can only run on a single ccd. Even though the 7950x3d has 16 cores games will never have access to more than 8

It's even worse for the 7900x3d as it's stuck with 6 cores for gaming

I should have expanded my post a little. Consider a game that uses all 8 cores, like Cyberpunk 2077 at 4k with RT enabled. If you run any background tasks (discord, youtube, spotify, maybe some download, etc etc) these will be demanding cores/threads to run on.

On the 7950X, the CPU will simply 'wake' the parked CCX and assign those background programs to the spare CCX. What will happen for a 7800X3D? The game will slow down, suffering from lower minimum FPS values.

This is from my testing with a r5 7600, r7 7700 on a X670e Hero. On the intel side, I tested with a 13900k.

While the X3D CCD is handling the gaming workload, the cores of the second CCD are parked, and woken up as needed for background tasks.

Remember that these reviewers are typically using fresh windows 11 installations, no RGB software, no common applications running in the background. The average buyer of such a CPU is not going to run on such an optimized setup.

He makes some good points in that video, can come across as abit extreme in general from the small amount of videos I've watched of him that takes abit getting used too.

Regarding his baldness I agree he needs to do a full delid. :D

Seems to be pro Intel from what I’ve seen (not much to be honest).

He talks far too much about how he’s tuned ram etc but I’ve not seen him show anything.

based on this how will the 7800x3d likely perform in msfs, better or worse than already impressive 7950x3d?

No one knows, however I expect the 7950X3D to be the fastest overall once tuned, just like the 7950X. However, the 7800X3D might be as fast or slightly faster out of the box, just like the 7700X is Vs the 7950X.

this is exactly, why i wanted more than just 8cores with x3d.
on my old rig i could not game and have my firefox open in the background, because it caused the game to loose massively performancewise.
whenever i buy a cpu i want it to stay as long as possible in the rig and in this case the 7950x3d seemed to me like the best choice.
btw. ordered mine this afternoon for just 690.-... minutes later the shop toke down the x3ds again, because they opened up the sale one day to early... lets hope my order counts anyway... XD
 
Not that anyone really cares, but has anyone seen if they have benchmarked BF2042 with the X3D chips? I'm currently obsessed with that game for some odd reason. Not that getting an X3D chip will make me a better player.. but I'm just curious to see if there's a significant performance boost.

Same price as I paid for the 5950X at launch tbf.

Don’t know, imagine it’ll be similar.

The difference is its fighting a 13900K at £580 so that is a large chunk more relative. If it had come out at £690 ish that difference if you was looking now isn't quite that bad and it's still a £140 more than you can pick up the 7950x.

Just seems too much of an uplift in current market.

So are you saying a 4090 playing Cyberpunk using DLSS quality would see a bigger differential between the two cpus than in traditional raster? (which is 9%), and that differential is worth the extra £500?

I'm saying you need to have a fps target and see if the CPUs in question can hit that in the first place, because that's the relevant metric, rather than what the relative performance differential is in a situation you won't (accept to) be in.

F.ex I target 120 fps in certain games (let's say Cyberpunk), so that's a relevant target I pay attention to. A 7600X can't hit that in games I care about, so that it's near equal to a 7950X3D at 4K at a target framerate below what I choose to play at is irrelevant.
