GTX 1030, ultra budget card

GP108-300-A1 chip, SMMs - 3, 64bit bus, 48Gb/s bandwidth, 942 GFlops

GTX 1050 / 1050 Ti, budget cards

GP107-300(400)-A1, SMMs - 5(6), 128bit bus, 112Gb/s bandwidth, 1733(1981) GFlops

GeForce GTX 1060 3GB/6GB, medium card

GP106-300(400)-A1, SMMs - 9(10), 192bit bus, 192Gb/s bandwidth, 3470 (3855 ) GFlops

GeForce GTX 1070 / GTX 1080, advanced cards

GP104-200(400)-A1, SMMs - 15(20), 256bit bus, 256 (320)Gb/s bandwidth, 5783 (8228 ) GFlops

GeForce GTX 1080 Ti, top cards

GP102-350SMMs - 28, 352bit bus, 484 Gb/s bandwidth, 10609 GFlops

You can see extreme savings on design, as all cards consist from literally same blocks, just different number of them.

Interesting view on prices if you just look how much they charge per SMM block

Two dips are due to cards with low memory amounts.

Chart for Russia (got close to minimum prices).

I've compared GTX 1060 and GTX 1080 only.

H264, GTX 1080 encodes 70% faster than GTX 1060

HEVC, GTX 1080 encodes 140% faster than GTX 1060

Interesting discovery - actually GTX 1080 have TWO encoder blocks.

Also note that outside Quadro they block more than 2 streams.

When looking at benchmarks 1070 & 1080 are the two GPU's that are high performance. With the 1070 being the best $ per CUDA core. I think that the 1080's memory bandwidth is the limiting factor.

It is not true, see charts with dollar per SMM. Best are 1060 cards for US.

Also made for you memory bandwidth per SMM chart

I was looking more at these sort of benchmarks. A 980ti is much faster than a 1060. However a 1070 is basically on par with a 980ti yet uses less power.

I see zero reason to get 900 series cards now. Until may be if you get some amazing deal on top ones and use Resolve.

Simplest thing is to just get 1080 Ti and go work if you use raw/ProRes and heavy grading. Instead of spending time.

If just editing weddings and similar stuff, 1050 Ti /1060 6GB is enough for years ahead.

Yup. 1080Ti, however I also have my eyes on Vega. I'm thinking of a few 1080Ti's for rendering- or Vega's.

Will reassess when the star falls!

Nvidia encoding

And decoding features

Note for high bitrates it is almost no reason to use software encoders

Howdy, Stranger!
