[FFmpeg-user] RES: Nvidia professional cards for li e transcoding

[Pedro Daniel Costa]

Ok thanks

I will try to get the V version

We need to have a reliable streamer hardware to run 50% capacity lets say I want to trasncodg 50hd channels and 50sd channels I want to run half capacity of the hardware

We already have a Dell R910 server with 4 Xeon 8core cpu with 256GB RAM with 2SSD RAID mode , just ordering the Nvidia professional card now and wait for it to arrive to give it full testing.

I would confirm that K80 is indeed newer.  I think K stands for Kepler,  M for Maxwell, P for Pascal, and V for Volta.  Volta is the newest on that list, and Kepler is oldest.  Kepler's NVENC doesn't support HEVC encoding, I'd avoid it just for that.
