first i tried Topaz VEAI V1.7.1 on an Asus RTX 3070 OC 8GB.
The render times dropped 60% compared to my 1050ti. Nice power boost.
(My system: CPU I9-10900KF with 32gb 4266 ram. Z490 chipset, Win10 pro 2004)
(I know that my system only has PCIe3, but professionel hardware testers like tomshardwareguide say the difference between pcie3 and pcie4 with an RTX3090 is just 1-2%)
Harddisks are 1TB and 2TB nvme … 3500mb/sek read 3300mb/sek write
But i still was not satisfied with the “long” rendering times.
And so i decided to buy a nvidia 3090 Founders Edition.
I was hoping the 3090 is at least double as fast as the 3070 with topaz.
When we compare the specs it should be and looking at 3x the price of an 3070 - it REALLY should.
But before i exchanged the cards i prepared a decent list of to be rendered videos and noted the RTX3070 render times (frames per second). It was all kind of different videos in resolutions from 240p up to 2160p.
After the hardware change and the reinstall of the studio drivers i reloaded the 3070 queue list and tested the videos again on the RTX3090 - 1:1 , 3070 vs 3090
And the results were more than disappointing.
I will not copy my complete results, but i can say with 3070 it took 7hours of upscaling a 1hour video from 720p to 4K (2160p).
With the 3090 it takes “only = still” 6 hours of upscaling the same video to 4K.
So the 3090 saved me “just” 1h rendering time.
Shouldn’t that at least be 3 saved hours ?
video1 8h30min 0.25sec/frame — 6h40min 0.20sec/frame
video2 6h55min 0.25sec/frame — 5h40min 0.21sec/frame
video3 8h45min 0.34sec/frame — 7h05min 0.27sec/frame
At this very moment my results dont cover the 3x higher price of the 3090.
The 3090 is hardly 20-30% faster than the 3070. How comes???
Did i miss something? Do i calculate wrong?
(btw. before the nvidia RTX3090FE i got an Zotac RTX3090 … results were exactly the same)
Most recent game ready or studio drivers make no difference.
I hope the “bad=slow” results of the 3090 come from not fully developed drivers yet. (12/2020)
OR Topaz VEAI does not fully support / use all capabilities of the RTX3090 yet?
I hope future updates will boost the performance.
I also recognized (via Asus GPU Tools) that VEAI 1.7.1 only uses 8GB max. of my 24GB GPU Ram.
Even when i start VEAI twice and render 2 videos at the same time. it never takes more than 8GB.
Someone really needs to look at this bad performance…
Otherwise the 3090 will never be an option for Topaz VEAI users.
Its not just the price … that will drop one day…
But remember the 3090 needs far more electric power than the 3070 …
3090 350W - 3070 220W … During winter times thats okay for me as i could switch off the floor heating… The 3090 is quite some hot hairdryer I now fear a hot summer day …
Soooo IMHO the 3090 should save ~50% of the rendering time…
compared to an 2080 or 3070 … otherwise its a waste of money
P.S. at least i never had broken videos from the 3090 like others mentioned above…
