So I played around with trying to make TVAI as fast as possible with my setup, and I decided to share my results with everyone in case this helps anyone.
CPU : Ryzen 5800x (16 Logical Cores)
GPU : Rx 7900 xtx
RAM : G.Skill 3600 C16 32GB (Originally 16 GB)
Just as an FYI all results were with Iris ( v1 for those in the future ). I used the Windows task manager to monitor how utilized my different components were. I know some users do not like this monitor but when I double checked it with other monitoring software I found the results comparable.
Originally when I was rendering a video from 1080 to 1440, my CPU would be utilized about ~75 to 80 percent and my GPU would be utilized about ~38 to 43 percent. According to TVAI I was processing about 3.2 frames per second (FPS).
I started to think about how to speed up my processing for frames per second. I realized after a little bit I never enabled pc RAM’s XMP on the motherboard (O.K. this is an AMD platform so D.O.C.P. for those who want me to be technically correct). I found after enabling the RAM’s XMP TVAI had a jump in performance. The CPU started sitting at about ~80 to 83 percent utilization while the GPU was at ~48 to 55 percent utilization. Processing FPS jumped up to 3.8 which was about 18 percent (17 - 18 percent from 3.2 FPS? ).
After seeing how much the ram speed increased the processing FPS I decided to start using dual channel RAM configuration. I found the results was other 10 percent increase in processing FPS. The CPU still sits at about ~80 to 83 percent utilization while the GPU is now at ~55 to 65 percent utilization. The processing video FPS is now about 4.2.
So from my experience RAM speed makes a big difference. I know this should not come as a shock to anyone. 3.2 to 4.2 processing video FPS is a big jump. I don’t know why my CPU will only be utilized at the max by ~80 percent. I thought maybe originally that my CPU was data starved but that does not seem to be the case.
I decided to process two different videos at the same time and see if that would better utilize everything. I found my CPU will then run at 100 percent utilization, and the FPS of the processing videos run about ~2.4 FPS each which is equivalent to 4.8 processing FPS.
In conclusion, I found that RAM speed makes a big difference and running two different copies of TVAI will also improve efficiency. I don’t know why TVAI can’t use 100 percent of the CPU when two copies of TVAI can.
P.s After a AMD driver update the GPU is now running at ~ 48 to 55 percent utilization but still 4.2 FPS video processing. I wonder how much more optimization AMD can make with its drivers.
