Same video also showed the 5900x at around 12% usage and was running at up to 80 degrees, looking forward to the reviews when the real ones materialize.

Still running a 3070. So could be limiting frames and not seeing the full picture
Yeah, that video was posted earlier....
How is the 5900X behind the 5800x and 5600x in some games:
650W is more than enough.Hey guys can i get your opinions on my build it is aorus elite b450(i know b450) just dont the will power to change out the motherboard and its causing no issue hopefully a ryzen 5 5600x, asus dual 3070 non oc, vengeance 16gb 3000mhz ram now i know its recommended to have probably a 650 watt power supply in this build but since the cpu is only 65 watt i think im just coming to like 450 watts used and thats plenty of room.

Yeah building new rigs for both the wife and I so needed two and the price was too good to pass up - they are eligible for £55 cashback each as well (although probably only once as I did them in a single order!)
They can still be had for £399 and £55 cashback though.
Thanks for that explanation.Well, it's not that surprising. 5800X has 8 cores but within a single CCX, in simple terms it means that all 8 cores are in a single cluster, so they all share the same cache, they can switch context(threads) very very quickly with minimal penalty. The 5900X has 12 cores, but in two 6 core clusters instead. There is a connection between the two clusters, but it slows down any kind of cross-core, cross-thread communication if those threads don't run on the same cluster. Since games generally won't be aware of the CPU architecture, they could be getting penalized for this communication between clusters and end up being slower. This is not exactly new. The 5900X is still going to be much faster in situation where cross-cluster context switching doesn't happen very often, or where threads don't share cache data. It's highly situational basically.
I suspect an overclocked 5800X will be the best choice for games due to having only a single CCX and not having the penalty of crossing the infinity fabric. The 5900X will absolutely rule in multithreading and when compared at stock it might be faster in some scenarios due to being clocked higher. But if you're willing to overclock a bit and *only* care about games, then 5800X is probably the better choice. I do a decent amount of video encoding so I'm aiming for 5900X, but I'm not sure if that's the best choice if you only look for a gaming CPU.Maybe the 5800X has less latency due to it having one CCD.as some have said ? The the 5800x maybe the best gaming choice ? my head say 5800 my heart says 5900
Thanks for that explanation.
So, what do you think the 5950x, with 8 cores per cluster, will perform like? Will the first 8 cores in a single cluster be automatically used in order to make best use of cache?
On the mainframes I work on, the hardware/software attempts to dispatch programs on the same cores in order to make best used of processor cache etc. I assume these AMD chips would do similar.
Really hope the reviews don't go live at the same time as release
Hey guys, upgrading from a 1800x on a b350 tomohawk, would i need to upgrade the mobo for the 5600x?
