AMD Radeon R9 Fury X Video Cards in 4-way CrossFire at 4K

Performance at 4K


Battlefield 4: We start off our 4-way Fury X journey with Battlefield 4, where we have a stable 60FPS with a single card. We have some great scaling with 2-way CrossFire, with an additional 75% performance. But, the third and fourth Fury X cards do absolutely nothing to our frame rates.


GRID: Autosport: This is another game that I knew wouldn't scale well on 4-way GPUs, with a single Fury X managing 83FPS. Adding in a second Fiji-powered Fury X and we see 117FPS, providing us with scaling of 41%. But the third and fourth Fury X cards do nothing to the frame rate, adding just 1FPS to the average FPS bringing us up to 118FPS.



Metro: Last Light Redux: I actually expected more performance here, but moving from a single GPU to dual GPUs provides a large 83% increase in performance, while we only have another 3FPS from another Fury X, and a further 3FPS when adding in the fourth Fury X.


Shadow of Mordor: This is a game that I knew we would see better CrossFire scaling, kicking things off with 45FPS average on a single Fury X. Another Fury X provides 81FPS average, where we have 80% scaling. The third Fury X adds another 33% performance, while the fourth Fury X boosts us up by another 12%.


Thief: Thief is usually a game where we see great multi-GPU scaling, but anything above two GPUs is unused. Instead, we see a huge increase in the minimum FPS, where on the single and dual-GPU setups we have 7FPS compared to 23FPS minimum and 34FPS minimum on the 3-way and 4-way setups, respectively.


Tomb Raider: Tomb Raider has nearly perfect multi-GPU scaling, where we have 62FPS on a single Fury X and 119FPS on the CrossFire setup, showing us 92% scaling. The third Fury X adds another 50% performance, while the fourth Fury X adds another 29%. This is the best example of the 4-way Fury X cards yet.


BioShock Infinite: The single Fury X performed well, with 52FPS in BioShock Infinite, with 71% scaling for the second card. Adding in the third Fury X had us bumping up performance numbers by 19%, while the fourth Fury X actually resulted in less performance at 103FPS average.



Power Consumption


A single R9 Fury X uses around 350W of power, which is not too bad at all, but as soon as you throw another card into the mix, the power consumption continues to climb. 3-way and 4-way GPU systems are always power hungry, with the 4-way R9 Fury X setup being no exception.




As you can see, the single R9 Fury X uses 360W, while two use 560W, three cranks it up to 800W, while 4-way R9 Fury X uses 1000W. During our testing, we found that Tomb Raider was quite good at 4-way scaling, with it using up to 1260-1300W of power. An insane number by any standard.
