AMD equivalent of GTX1080

[Jonj1611]

What is the AMD equivalent of a GTX1080, not bothered about prices at the moment, just interested in what would be an equivalent/similar card?

Thanks

Its direct competitor was the Vega 56 / Vega 64, both of which are decent cards offering 8Gb vRAM. The Sapphire Pulse was an excellent option, or the Sapphire Nitro+

Before that it was the R9 Fury X, R9 Fury, and Fury Nano which competted against the GTX 980 Ti and GTX 980. All three sit somewhere between the 980 and 980 Ti, generally speaking, but only have 4Gb vRAM, so the GTX 980 Ti 6Gb was the king at the time.

For more recent cards, it sits between the 5600xt and the 5700 non-xt.

Thanks for the feedback. Soooooooo due to something or another I am currently moving to the imac for a while but gaming performance isn't great so looking at an external gpu. I have a 1080 but apparently Apple and Nvidia don't get along and officially supported egpu's are AMD's :/

Both of which were unfortunately cracking mining cards, so impossible to get new. There might be a lot of them turning up second hand soon though

The 6700 XT is a rubbish mining card, and so is at least readily available but as one of the few cards you can get hold of the price is pretty silly.

For a really rough guide, I find TechPowerup quite handy: https://www.techpowerup.com/gpu-spec...gtx-1080.c2839

I think your best hope right now is that the 6600 XT is supposed to be close to release. That comes with a chance of getting one at RRP on release day which would get some hardware in your hands, though I've no idea what the Macos driver support would be like on new GPU hardware.

[Jonj1611]

Many thanks, generally the driver support is fairly good even on release, well for newer cards anyway. You can get an Nvidia to run but its a faff to be honest.

I would even have consider geforce now if they actually supported any of the games I play, which for the most part they don't.

Surprisingly a lot of my steam library runs on the mac.

Wonder if anyone has seen any tests looking at how RDNA2's infinity cache does with eGPUs where Thunderbolt is a limit?

Shouldn't make any difference - the GPU to VRAM communication still happens internally to the card.

[Jonj1611]

The enclosures are a stupid price aren't they?

Ah, that makes sense - infinity cache is trying to solve a different bandwidth issue. So I guess, the more VRAM the better for eGPUs so that VRAM flushes are as rare as possible.

Yes, all other things being equal. Better compression and fetching only needed textures also lower card interface requirements.

Yeah, about the price of a card again I seem to remember.

[Jonj1611]

Yes indeed, can't find any cheap ones or even reasonable priced. Going to have a think about this one.

They are rather niche, but occasionally (and way before the current GPU drought) there have been offers - or maybe even sell offs - on hotukdeals. Don't recall seeing any recently though.

Vega 64 and the RX5600XT/RX5700.

Incoming from left field....

Would it be cheaper to get a cheap motherboard and CPU for the 1080 and run SteamOS on it?

[Jonj1611]

I actually have my main system still and the idea is to break it down and just use the mac for the next couple of years, however I seriously miscalculated how naff gaming is and while I have hundreds of games I only actually only play a few, most of which apparently will work just fine, the others just wont cut it so was thinking of keeping the gpu and using it externally, however external housing costs are just stupid so I wouldn't gain anything from that.
