It looks like a 128Bit memory bus will not cause performance issues with multiple transcodes but will see Plex offline “Sync” jobs only able to use 30% of the NVDEC chip. The difference between the 128Bit, 192Bit and 256Bit Memory bandwidth needs further testing. ![]() A 256Bit GTX 970 4GB (Maxwell 2 nd Gen) can hit 100% NVDEC saturation (376FPS) with a single stream. Two streams hold about 50%, Three about 80% and more than four streams to reach 100% NVDEC saturation. Preliminary testing sees a single NVDEC job on a 128Bit GTX 1050 Ti 4GB (Pascal) unable to use more than 30% (112 FPS) of the NVDEC. ![]() *VDPAU nVidia PureVideo Information VRAM Bandwidth ![]() *NVENC FPS based on Single Pass quality profile.
