Hardware HEVC encoding
Hi all,
I have a GeForce 1660 Turing card and Ryzen 2400G CPU. I use Staxrip to encode 1080 TV rips using NVENC HEVC 10 bit and usually opt for 2 channel audio. I get good results with file sizes of around 800-1000 MB per hour of TV. Encoding runs at 166 fps with the GPU running at 100% and the CPU about 60% on 8 threads. I am thinking of upgrading the CPU to a Ryzen 3600 or 3700x (probably the former as it is well priced just now). My question is, will I get much if any fps increase in encoding speed? Not crucial as 166 fps is quick anyway but any info to help my buying decision is welcome. John |

You probably won't see any appreciable gain as these are similar speeds that people are getting with a 2080Ti
FPS for SD channel. for 720 divide by 2, for 1080 divide by 4 GPU DEC H264 H265 POSTPROCESSING GTX 1070 2600 2600 1800 5000 GTX 1080 2600 5200 2600 10000 GTX 1080 TI2600 5200 2600 10000 RTX 2080 5800 1700 600 5800 RTX 2080 TI5800 1700 600 5800 https://devtalk.nvidia.com/default/t...c-in-turing-/2 |

Just installed Ryzen 3600 and as predected no change in fps with NVENC. Handbrake fps have more then doubled for 1080 10 bit HEVC software encoding.
Hope this info is useful to someone else and thanks for the help. John |

Well that's about what you would expect, seeing as you upgraded your CPU and not your GPU. NVENC is executed on the GPU through a dedicated chip, your CPU wouldn't really change any performance unless it had previously been unable to supply the GPU with frames fast enough to keep up with its ability to process them.

Perhaps you can have a gain on filtering, but i dont know how staxrip work. If You dont use any filter on video converstion just consider on better MB chipset / ram / ssd (but if videocard dont change i'm not really sure it can help) |
