Is Four Always Better Than One?
No. It's quite a simple answer; 4-way GPUs doesn't always offer a great experience. This isn't limited to AMD either, with 4-way SLI systems performing just as badly. We will be doing some 4-way Titan X and 4-way GTX 980 Ti in the near future, where we will be able to compare performance between the best from AMD, and the best from NVIDIA in one massive, hardware showdown.
For now, 4-way GPUs sucks balls. The performance benefits from a single Fury X to 2-way CrossFire are great, and in all of our games, the performance is much better. You're looking at around an average of 70-80% performance gains on a 2-way setup, which is worth the money.
But the performance gains fall off of a cliff in most of our games, with around 30% gain for spending another $649. The fourth GPU just sits there using power, as well as costing yet another $649. If you're benchmarking all of the time, then 4-way GPUs are always great. If you're only playing Tomb Raider, then you might want to look at 4-way GPUs, but in reality we know that's not going to happen much of the time.
What would I recommend? Well, we're looking at 4K gaming, so let's start there. A single Fury X provides between 35-60FPS average in our games. A single card is not enough to enjoy 60FPS minimum, which is where a second Fury X steps in. Fury X in 2-way CrossFire is the best price to performance, as you're going to enjoy 60FPS+ in virtually any game on the market at its highest settings.
As it stands, if you want to game at 4K and you've got the money to splurge out on 4-way Fury X cards; don't. Grab yourself two of them and use them in CrossFire, and you'll have 4K 60FPS+ gaming enjoyment and you would've saved $1300 in the process.
In the future, we should see much better multi-GPU scaling from our games thanks to Windows 10 being here, which includes DirectX 12. Game developers need to start getting elbow deep in those tens of millions of lines of code, and optimizing it for multi-GPUs. Secondly, VR is going to need serious GPU horsepower. VR gaming is aiming for 1080p 90FPS, so we're going to need at least a Fury X for that. 2560x1440 @ 90FPS is going to require the same amount of GPU horsepower that 4K 60FPS does, if not a bit more as you're going to want 90FPS minimum versus 60FPS average at 4K.
I think that VR is the tipping point of both AMD and NVIDIA pushing developers to get better multi-GPU scaling, especially when we look at AMD's use of Asynchronous Shaders, DirectX 12 finally being here, and new architectures from both AMD and NVIDIA being around the corner.
