I am a little bit of confused to choose between K4000 or Tesla C2070. I saw the benchmark of Wowza here in which Tesla is the most powerful Graphics card, but it was long time ago. So I have some questions, hope you can give me some advice:
1. Do both of them support NVENC, I know that surely K4000 supports NVENC, but I don't know about Tesla branch.
2. Do you have a performance test (if it has the same with Wowza benchmark, it would be great) with K4000 card. Because I'm not really sure about the performance between K4000 and Tesla. My objective is to receive about 40 4CIF incoming feeds, transcode them into 4CIF and 1CIF (with watermark) streams for each feed.
3. For transcoding, which one is better to use, NVENC or CUDA ?
Thanks for your help guys, I appreciate all your comments,
