2070 x 1 VS 580 x 2 (crossfire)

Hey guys.

I guess the title says it all.
I can get 2 x 580's for pretty cheap.

But i'm wondering about crossfire.
I've always used SLI with Nvidia, but the new line of 20 series cards are a bit pricey.

Does Crossfire work as well as SLI ?
Will i have comparable performance with either setup ?

PS : This will be with an AMD 2700X, no OC on the cpu or gpu's

Thanks

If your asking if you should buy a 2070 vs 2 x 580 then the answer is pretty simple. Stick with a single more powerful card and later if you wish, get a second 2070.

I have 2 580s

Crossfire support is basically HORRIBLE, lol

The few games that work, work well and get close to 100% scaling. I would rather a single more powerful card

2X580s are prolly like a single 2080. They need a powerful cpu.

Crossfire is abysmal by itself, but doing dual GPU with such bad CPU is abysmal overdosed. Also, 2x580 is nowhere near 1080Ti.

In games that don't scale, yes, the 580s are nowhere near a single 1080Ti. But in games like BF4 or C3 they are near. Not having anything to compare them with except Firestrike GPU score . . . i read the RTX 2080 gets 27000 Graphics score. About same as my 2X290s. The 580 is a tad faster than a 290.

And you are right, crossfire or sli will need the right cpu to support them at 2X580 level.

Firestrike scales greatly with anything, reality is, Crossfire is close to not working, as you might get very high FPS but your frametime rises twice as much too.

I've used crossfire 290s. I had to 3 yrs ago bcos of 4K. After the HD 7000 series, Crossfires where much improved surpassing SLi. Its been known here in OCN and other tech forums. Getting rid of the bridge was one reason. Recent titles though have less support for multi-gpus.


Oh wait, you are relatively new to OCN.

So much of an improvement that Crossfire is broken, officially at EoL and there is little noise from SLI users if they don't expect things to just work. Removing the bridge was a mistake.

An article back in 2014 after XDMA was implemented . . .
