R9 390X crossfire with RX 480?

[ZTN]

Can a sapphire R9 390X crossfire with the new RX 480 just wondering if anyone knows or the probabillity of it

[I need a better name]

No

[Kinda Bottlenecked]

No.

[TheRandomness]

0% chance because completely different manufacturing process.

Really? Why?

Different architecture.

390 = 28nm manufacturing process

480 = 14nm manufacturing process

 

You could crossfire the 290 and the 390 because the 390 is a 290 with optimisations in terms of power delivery and drivers.

Sell the 390x and get 2x rx480.

Because they are completely different graphics cards. Only the same card or a closely related one can be used in Crossfire.

[Carclis]

Assuming those cards did actually work together you would still find very few people on this site who would recommend crossfire. Support is not great with some drivers coming a month after a games release if they do at all and scaling is not always great.

with the same gpu, like the 7970 & R9 280x 

and the 7950 & 280

You can only CF cards that has the same chip architecture.

Ah alright anyways i guess time to sell my 390X

Supposedly (not confirmed), the 480 is to be slightly faster than a 390x. If you want a new GPU you're better off waiting for Vega or even the RX 500 series.

[ZTN]

Yeah but i would save money and i plan on getting a dual GPU setup with an RX 480 or possibly 490

[LooneyJuice]

I'll echo most people. Stay away from Multi-Gpu, both xfire and SLI. If you're willing to spend that amount of cash on 2 GPUs, which will more than likely amount to more than $400 depending on the version, you might as well go for a single GPU costing that much. Sure, the theoretical performance may be worse, but the actual performance will be better in every single scenario where a Multi-Gpu setup will fall flat on its face. Not to mention all the fancy new DX12 features will, first, only be in DX12 games (DX11 games will still suffer the same issues), and even then only DX12 games in which the developer has accommodated Multi-GPU setups. Additionally, we have no Idea regarding actual RX 480 performance from 3rd party benchmarks yet. So, don't put all your eggs in one basket, and so on, and so forth. A little patience goes a long way for your bang for buck.

Why?  You will be getting very similar performance.

After reading alot of this i might just wait for the benchmarks to come out and take a look for myself + if i were to sell my used R9 390X for 400$ i could still buy the RX 480 for like 300$

You might lose a few FPS... wait for the benches and open air coolers(non reference).

Open air coolers?
