This is a good news story. Decided to move my RTX 3060 ti temporarily from its usual Ryzen 7 5800x 8 core / 32GB memory home to my old i7 6700 (2016) / 16GB memory system - just to see how it performed on TVAI 3.1.4 - trial version.
The speed results were excellent! On Artemis HQ, an old 640x480 2 times upscale ran at 23 fps on the 5800x but on the 6700, it still ran at 22 fps. I got 85 fps on Chronos Fast 2x slomo, not much slower than on the 5800x (95 fps)
This was only a small snapshot but the moral of the story is, for anyone needing faster throughput on upscaling many old videos, don’t spend £1K or more on a 40 series upgrade without first checking the performance of your existing GPU on your older system if you still have it.
So I can achieve a far greater throughput than even a 4090 on one system would provide, by buying one extra ‘cheap’ 3060 ti for my 7 year old system. The licence seems to allow this, so food for thought, all you potential upgraders out there.
Well, CPU and GPU have to be in balance.
I don’t have to PCs, but I experimented a bit with tuning my Ryzen 7 5800X and the RTX 3060. Overclocking CPU from 4.25GHz to 4.5GHz resulted in 10% more power draw while TVAI speed went onyl <1% up. Same effect with GPU overclocking from 1800 MHz to 2200MHz, that did also not increase processing speed.
Therfore I run my system with CPU @4,25GHz and GPU @1800MHz, both >90% load.
I can process comfortably 3 videos in parallel (Proteus, 2x upscaling) with in total ~10fps speed, and have almost no negative impact on other work done in parallel.
Usually I load a sequence of up to 9 videos, activate them all for export, and let TVAI do the job 3 after 3. Off course I care that during that processing I don’t need to reboot the PC (no need to worry for overheating)
I always thought that but what I’m suggesting, at least for the kind of upscaling and slomo that I do, the CPU and GPU do NOT have to be in balance (within reason).
Because with the same modern GPU, I got 95% of the same speed with a 2015 released i7 6700 as with a 2020 released Ryzen 7 5800x. That surprised me - and as I still have the 6700 system I no longer feel the need to upgrade to an RTX 4000 series and bigger PSU for faster throughput, I can just buy a much cheaper 3060 ti for the old PC, use the same PSU and run both computers as and when I need to.
I can run two instances of TVAI too on the 5800x system, not sure about the 6700 setup yet as I haven’t tested it for that.
I’ve never much been interested in overclocking or fast memory tbh but I may try it now.
Incidentally, the 6700 system has its original GTX 1070 ti back in it now. It runs the same 640x480 video at 2x upscale - Artemis High - at 10.5 fps, compared to 22 fps with the RTX 3060 ti. I have an even older i7-4770K system with 8GB RAM and a 1070 GPU, that does it at 8 fps but I’m not planning to test it with the RTX 3060 ti.
