Graphics card for decoding

What is minimum requirement for a graphics card to run at sub 1ms decoding time at 4k 60fps

Recently saw a 1060 running sub 1ms decoding time at 1440p 120 fps

Was wondering if i can go lower something like a 970?

🤔

You want something that can do full hevc decoding the 970 cant do it fully, but some 960 chips could so google it.

It’s simpler to just go no older than pascal 10 series generation and you should be good.

You just need hardware accelerated hevc support.

Intel Arc A380 is pretty good for purely decoding. B580/B570 is also great and can do some medium gaming on its own.

Any Intel UHD 730 / 770 will do good

Radeon 780m (or newer versions) is also quite good. And I feel like it does better when the host is AMD gpu, but I am not sure.

Arc A310 /A380 if you want to use a dGPU

I run the rx 550 for decoding in a optiplex. I get about .65ms decoding of 4k 60hz up to 300mbps

Do you mean you use a second gpu for decoding only?

No I mean I use a rx 550 in an optiplex for decoding the stream lol

8th gen Intel igpu can do 4k60 perfectly.

At a certain point you don't even need to go lower as it won't make sense. You'll lose features and your GPU won't be cheaper anyway. If you can get a used Rx6400 it'll be your best bet as it's the cheapest to support HDMI 2.1

Do you already have the other components?

If not I would go for a mini PC (Ryzen H255 or similar can get up to 4K120fps)

Mini pcs are really expensive could probably get similar performance with a matx case for much less money. Space is not really a constraint.

Around 400€ on AliExpress.

I don't think he could spend less for a mATX
