Ryzen 7 1700 vs Ryzen 9 3900X render times

I like to post render time comparisons when I upgrade a cpu, figure the data could be of use to others contemplating an upgrade. I just upgraded the cpu only, so all other components remained the same. Main pc has 16gb ram, 1tb nvme ssd and NVidia 1080ti. I have all gpu support enabled on both encoding and decoding. Source footage has watermark and Film Convert color grading effects added on to the source 100mbps 4k xavc footage from a Sony A73 camera.

The way I do my encodes is make a main encode right from Vegas Pro 17, then I use the Handbrake app to make a 720p version from the 4k file after the fact as I need both versions, so each time represents how long the respective apps took to encode. It was just a short test file so that it wouldn't take forever. Times are below.


Ryzen 1700 (8 core cpu)

Vegas Pro: 9:42

Handbrake: 4:47


Ryzen 3900X (12 core cpu)

Vegas Pro: 8:26

Handbrake: 2:40


I use handbrake a lot and that's the software I tend to wait on so I'm very happy with the performance upgrade, Handbrake really takes good advantage of the new cpu. Vegas Pro on the other hand doesn't seen to, I guess that means there's a bottleneck somewhere else. I know the bottleneck is not the ssd as it reads at 3000mb/sec (nvme right on the motherboard using 4 pcie channels) so maybe the NVidia 1080ti is the bottleneck, not sure though. Either way, kinda disappointed in the Vegas Pro times but the Handbrake times are awesome, very cool just for a cpu swap. Also got 2 free games with the cpu as a side bonus :)

It was 6:22 in length.

Look at Happy Otter Scripts. You could use two Vegas sessions and the FFMPEG encoder. Bury the system and go for a long walk on the beach.
