$400 Nvidia RTX 3060 Ti vs. my $350 VEGA 64 LQ (Liquid Cooled):
I snagged a MSI Nvidia RTX 3060 Ti during the whole 10 minutes Best Buy had them in stock online, it arrived, and I ran our Vegas benchmark tests using Nvidia Studio driver 460.89, release date 12-15-2020. Tests were run on my 9900K workstation clocked at 4.8 ghz with variable speed enabled for silent running with my VEGA 64 LQ (also silent) at stock settings. It was removed and the 3060 Ti was also run at stock settings. Tested using Vegas 18.373 with source video on one fast M.2 RAID & target going to another M.2 RAID...
Red Car Sample Project to 1080p MP4
RTX 3060 Ti NVENC = 0:19, VEGA 64 LQ VCE = 0:15, (0.13 with CPU at 5 ghz)
Sample Project 4K to 1080p FHD 25 fps MP4
RTX 3060 Ti NVENC = 0:47, VEGA 64 LQ VCE = 0:48, N = 2% faster
Sample Project 4K to 2160p UHD 25 fps MP4
RTX 3060 Ti NVENC = 1:20, VEGA 64 LQ VCE = 1:38, N = 18% faster
Sample Project 4K to 2160p UHD 25 fps HEVC
RTX 3060 Ti NVENC = 1:28, VEGA 64 LQ VCE = 1:36, N = 8% faster
Preview FPS between markers in 4K Sample Project = 12-13 fps average, VEGA = 13
1 Minute Sample from a Client's Project to 4K HEVC
RTX 3060 Ti NVENC = 1:35, VEGA 64 LQ VCE = 1:19, N = 17% slower
(4) open instances of Vegas rendering 16 minute project to 2 intermediates, 4K HEVC, 1080p MP4
3060 Ti NVENC = 29 minutes, MP4 & HEVC done in 28
VEGA 64 LQ VCE = 29 minutes, MP4 & HEVC done in 25, N = 10% slower
(4) open instances of Vegas rendering (4) different 16 minute 4K segments to 1080p MP4
3060 Ti could only render (3) MP4 at once in 24:03, trying to start a 4th was restricted / impossible...
VEGA 64 LQ rendered all (4) MP4 in 22:01, 8% faster
Flight Simulator 2020: 3060 Ti = 40 fps 4K (high), 60 fps 1440p (high), 50 fps 1080p (ultra)
. . . . . . . . . . . . . . . . .VEGA 64 = 24 fps 4K (high), 45 fps 1440p (high), 42 fps 1080p (ultra)
Power Consumption: Regardless the GPU, the UPS powering the workstation, (2) 4K monitors & a 10G switch drew about 300W average during the (4) renders-at-once scenario...
12/21/2020 Update & Conclusion: Overall, if Vegas is your primary app, the 3060 Ti is NOT an upgrade from a VEGA 64, Radeon VII, 2070 Super, etc. BUT it is a modern $400 equivalent with some room to improve as drivers & apps are updated. IMO it is a good bang/buck at $400. In most other benchmarks, especially 1440p & 4K games, it outperforms the similarly priced AMD RX 5700 XT "Little Navi". I don't have time to buy & test other GPUs, so we'll have to see others' benchmark results to see if the other Nvidia 3xxx or AMD Big Navi GPUs are worth the price difference... I DO like Flight Simulator 2020 & revisiting some places I've been, so I might try a 3080 or 3090 if I can find one available...
