RX 480 and RX 470 Crossfire?

One of the more interesting features of AMDs CrossfireX is its flexibility. Different NVIDIA, AMD allows for dissimilar GPUs to be used for multi GPU configurations. The grab is, they have to exist of the same cadre derivative. Example: You could crossfire an HD 7970GHz edition with an HD 7950, but yous could also crossfire information technology with an R9 280x. I take done and then in the by with an Hard disk drive 7950 and a R9 280x out of curiosity. Same could be done with a R9 290 and a R9 390x, again same GPU core family. Y'all couldn't all the same crossfire a R9 390 with a R7 370, as they're both from different core families and GCN generations.  Well, I had both my RX 480 and a friends RX 470 hither on my desk and it striking me. They're both Polaris 10 based GPUs only one is cut down, much similar the HD 7950 to the Hd 7970. A quick search around the internet scored me no hits on whether anyone had tried this, and I came up empty handed. And so I decided it was worth a shot.

And BEHOLD, it worked. My Reference XFX RX 480 4GB and the MSI RX 470 Gaming X had no problem seeing each other and letting me tick on the 'Crossfire' pick. So while I had it at my disposal I wanted to come across what it could pull off. There won't be a full review of the MSI RX 470 Gaming 10 every bit it isn't going to exist here long enough for a review, but I do have a Sapphire Nitro+ RX 470 showing upwardly today so hang tight for that one.
Testing Methodology is the aforementioned equally we've used before where we mensurate the games frames using fraps and analyze them for the Average FPS, the 1% lows, and the terminal .1% lows. We've only tested a handful of games that nosotros know support multi GPU as nosotros only wanted to see how these two scale together rather than doing a full review.  All games were run at 1080p.

Test System:

X99 Exam System

CPU	Intel Core i7 6800k (4.1GHz)
Memory	32GB CORSAIR Vengeance LPX DDR4 2666MHz
Motherboard	ASUS X99A-Two
Storage	Crucial MX100 512GB SSD Seagate 2TB SSHD
PSU	Corsair AX860i

Cards Used

AMD Radeon XFX RX 480 4GB

(this card is flashable to both 4GB and 8GB configurations and volition always be stated which way it is in)

MSI Radeon RX 470 Gaming X 4G

*Both cards are operating at 100% out of the box clock speeds and settings*

Benchmarks

Battleground 4

DiRT Rally

GTA V

Ascension of the Tomb Raider

The Witcher 3

Determination

Information technology's interesting to encounter the scaling on these cards. It'south a fleck better than I expected information technology to be. Now is this something I would recommend anybody go out and do? No. But down the road information technology may go useful to know. Maybe you've got a RX 480 4GB already and you really desire that 2nd card, but can't detect i in stock or wouldn't mind saving some money but however getting a skilful boost. Betoken of this commodity being, it works.

*It's worth noting that this is not officially supported by AMD*
