Actually, an 8 core 5800x would give u almost the same performance as a 5950x. I usually only use the first 8 cores of my 7950x for tvai with a 4090. Your performance should be between 10 and 12fps on 2X, depending also on your RAM speed.
Fastest CPUs that board will take are a bit faster than my 5800x, and thatās a bit faster than yours. So your results worry me, as I am considering a GPU (+ PSU!) upgrade from my 3060 ti to a 4080 or 4090. But some of my benchmarks are similar to yours with your 4090:
,
System Model B550 AORUS PRO AC
Processor AMD Ryzen 7 5800X 8-Core Processor, 3801 Mhz, 8 Core(s), 16 Logical Processor(s)
Memory 32 GB DDR4 @ 3600 MHz
As you can see, your Artemis and Proteus 2x and 4x results are similar or worse than mine, though other results are much faster. But overall, with what I use TVAI for, the upgrade from 3060 ti would not be worth any extra cost for me, let alone a 4080/90.
This all leaves me wondering if other factors are at play here - CPU throttling or whatever. Either way, I canāt see that a CPU upgrade for you or me on our present boards is going to make a big difference. Maybe the mobo/CPU and memory sides need addressing too? Sorry that I canāt help more.
EDIT - One last thoughtā¦ have you checked for thermal throttling? That 4090 pushes out a lot of heat and if your case cooling canāt handle it, it (and/or the CPU) may throttle and cause performance loss. Just a thought.
As can be seen here again is, that at 1X, the GPU is the biggest performance factor. At 2X and especially 4X, the CPU/RAM speed becomes more important (due to image scaling + color correction being performed on the CPU).
The most powerful GPUs cant be fully utilized by TVAI atm, even with the fastest CPU/RAM when scaling @1080p or higher is involved. Only possibility is to run 2 TVAI processes in parallel on a CPU with 16 cores since TVAI doesnt scale much beyond 8 CPU cores for a single process leaving spare CPU capacity for a parallel 2nd job.
Hereās my results. Iām thinking of upgrading to Mac Studio M2 Max, Any advice from Mac users?
it looks like its nearly 3x faster than my current M1
Thatās because TVAI canāt really make good use of more than 8 cores, so the 7950X essentially performs like a 7800X (or 10700K) when running a single process.
The bigger cache of the 7950X is also not of much use because the TVAI tasks are more about streaming data (every frame is different from the previous one) rather than a longer operation on the same large data set, which is more common in games for example.
The advantage of a CPU with more than 8 cores, is that it will run 2 simultaneous TVAI processes faster than a CPU with fewer cores. Thatās ofc when the GPU is not utilized to 100% by the first task, which is usually the case when upscaling is part of the process.
Thx for your take on my thoughts and the analysis overall . Now I do understand better and take it into consideration, when building my upcomming gaming/work(photo-video-edit)-machine.
