Which low-power gpu for streaming pc?

[Sealance]

What's the lowest spec, in terms of heat and power usage, gpu that can be used to offload OBS?

I'll be using an i7 4770k and right now the current gpu is a Matrox g550 pcie 1x for testing.

Does that one not work? I wasn't aware you needed a GPU for encoding and streaming.

Pretty much any Nvidia card that supports NVENC/Shadowplay will work, so just get one of those with a low power draw (I think? the GTX 950 has support for it and that's a pretty low-draw card).

You don't *really* need one, but QuickSync (uses the iGPU) is pretty bad and CPU encoding isn't that great either (I max out at around 1366x768/30p at 10Mbps even on my 3770).

Well i was using the amd equivalent of nvenc in an underpowered am1 build and it did struggle slightly with 720p.

I have an avermedia live gamer hd that apparently has x264 encoding, and two usb cards (extremecap u3 and livegamer extreme)

Would a 1030 or similar work? Otherwise i'll try to dig up a 950 card like tmcclelland455 suggested.

You have the nVidia cards, anything higher than GT 1030 should have hardware h264 encoding , so probably GT 1050 or GT1050ti could be used. AFAIK GT1030 has hardware encoding disabled.

You also have the AMD cards,there's AMF plugin for OBS (may be built in latest obs versions) which should make it possible to use hardware encoder on RX video cards... I would say RX 560 should work fine,

Even RX 550 would work fine  - yeah, according to this benchmark result  at 1080p it can do 96fps (speed) , 81 fps (balaced) , 44 fps (quality)  and at  1366x768 it can do 181 / 154 / 86 ( speed/balaced/quality)

 

Your AM1 built probably used VCE, an older version of hardware encoding from AMD... the AMF stuff in the newer cards is much better, pretty much on pair with nVidia's stuff.

yes, that's it.. couldn't remember what it was called. Thanks

I'll avoid the 1030 cards then and go for either a 950 or 1050
