hello machine with 2 quad Hdmi decklink, 1 decklink 8k and 1 due duo.

64 gb ram
I9-10900X

I work with 1920x1080 50i
in legacy.


i change card video.


quadro rtx 4000 8gb or rtx3060 12gb or RTX A4000 16gb?
which one do you recommend


IMPORTANT to me is the minimum latency for live. I send video program output on sdi with decklink to projector

@ flippy,

Latency will be about the same with any of those cards.
The RTX A4000 is definitely the better of the 3 and has unrestricted encodes, but the GeForce RTX 3060 is otherwise not far behind in terms of performance with vMix.
The Quadro RTX 4000 is roughly equivalent to the RTX 3050 but will not be limited to only 3 NVENC encodes.

what do you mean by unlimited codes? as for the video sync of the screen outputs if I use 2 monitors quadro rtx4000 is equal to a4000 ?

i forgot vimx use cuda or gpu memory?
aren't 16 gb too many?

or is it better an 8gb p4000 framework? i don't understand difference between quadro p4000 and quadro rtx4000


thank you
