4gb ram laptop to broadcast ps4 live with capture card?

I have a laptop with 4GB Ram and a Ps4 that I would gamble on and stream Obs on my laptop with a capture card. That's enough 4GB Ram, because in the end I'm playing on the Ps4 and only streaming on the laptop

Has little to do with the RAM much more what CPU

I'm of the opinion that this is clearly not enough. You also need a reasonably good processor and graphics card to stream

And how much is needed because, as already mentioned, I only stream on it without doing anything else

Well, encoding in and of itself isn't too hard.

Should be enough in itself.

Assume later obs, which CPU does the device have?

2ghz
