Suggestion on dedicated Turing card for video decoding?

Post by Penden » Sat Mar 23, 2019 12:57 pm

Hello,

I have not been in the field for a long time and my gtx 460 (vp4) is aging. I am planning to get a Turing card on a budget that is only dedicated to DGIndexNV for video decoding.

I checked wiki that all Turing cards are using vp10 so I wondered. Are their video engines for video decoding exactly the same, performance-wise?

The gtx 1650 is supposed to be out at the end of next month. Price-wise, it should be the cheapest Turing card. If a pc that only gpu is a variable parameter, would the gtx 1650 (not out yet) decode as fast as the other cards such as gtx 1660, gtx 1660ti, rtx 2060,..etc? Or does the gtx 1660 decode as fast as the gtx 1660ti on DGIndexNV?

Besides, I also wondered if overclocking the gpu clock speed and/or memory speed in a graphic card would affect the video decoding speed of DGIndexNV?

Thanks

Great questions. We all have to wait to see. For pure decoding any VP10 will be great and the more PCIe bandwidth you have the better. If you are doing CUDA filtering then you want a lot of CUDA cores. I don't think overclocking the GPU helps the VP engine much, but I haven't tested that.

1650 and 1660 should be great budget choices.

Hello,

Thanks for the information.

Yea, the GTX Turing cards are still too new. I'll wait & check online how GTX 1650 performances after it's out.

1650 looks overpriced a lot for it's performance, so probably it worth to pay few more bucks for 1660.

Hello,

yes, the GTX 1650 based on TU117 is a bit pricey but the worst is, according to Nvidia and Techpowerup, that its multimedia/video engine is based on the previous generation, Pascal/Volta and is not based on Turing.

I guessed that the GTX 1650Ti would be on the same boat so now there are three choices from the xx60 Turing series (2060, 1660Ti, 1660) and I'll see which one to get then.

Saw this https://github.com/rigaya/NVEnc/issues/114 had title "GTX 1650(TU117) was castrated" :)
