I am trying to compare the number of simultaneous H.264 streams between GRID 1.0 and GRID 2.0.
The below link says that, “Each Kepler GPU has one NVENC hardware encoder that is capable of supporting up to 6 H.264 high-quality 720p at 30 fps.”
The three blogs below all note that the M60 and M60 cards support 18 and 36 simultaneous 1080p30 streams.
I want to verify if the below calculations of stream count are correct and if the Kepler NVENC is only measured in 720p30? I know from http://support.citrix.com/article/CTX201696 that 4k monitors are supported on a K2 passthrough via a Citrix HDX session. So, that’s just an example that the Kepler NVENC can support over 720p resolution. Therefore, I am wondering if there is an apples to apples comparison I can make between Maxwell NVENC and Kepler NVENC. In other words, are there any specs for the number of 1080p30 streams that Kepler NVENC can support?
K1: 4 GPUs x 6 H.264 streams = 24 simultaneous 720p30 H.264 streams
K2: 2 GPUs x 6 H.264 streams = 12 simultaneous 720p30 H.264 streams
M6: 1 GPU x 18 H.264 streams = 18 simultaneous 1080p30 H.264 streams
M60: 2 GPU x 18 H.264 streams = 36 simultaneous 1080p30 H.264 streams
