The AMD Radeon R9 Fury X Review: Aiming For the Top
by Ryan Smith on July 2, 2015 11:15 AM ESTThe State of Mantle, The Drivers, & The Test
Before diving into our long-awaited benchmark results, I wanted to quickly touch upon the state of Mantle now that AMD has given us a bit more insight into what’s going on.
With the Vulkan project having inherited and extended Mantle, Mantle’s external development is at an end for AMD. AMD has already told us in the past that they are essentially taking it back inside, and will be using it as a platform for testing future API developments. Externally then AMD has now thrown all of their weight behind Vulkan and DirectX 12, telling developers that future games should use those APIs and not Mantle.
In the meantime there is the question of what happens to existing Mantle games. So far there are about half a dozen games that support the API, and for these games Mantle is the only low-level API available to them. Should Mantle disappear, then these games would no longer be able to render at such a low-level.
The situation then is that in discussing the performance results of the R9 Fury X with Mantle, AMD has confirmed that while they are not outright dropping Mantle support, they have ceased all further Mantle optimization. Of particular note, the Mantle driver has not been optimized at all for GCN 1.2, which includes not just R9 Fury X, but R9 285, R9 380, and the Carrizo APU as well. Mantle titles will probably still work on these products – and for the record we can’t get Civilization: Beyond Earth to play nicely with the R9 285 via Mantle – but performance is another matter. Mantle is essentially deprecated at this point, and while AMD isn’t going out of their way to break backwards compatibility they aren’t going to put resources into helping it either. The experiment that is Mantle has come to an end.
This will in turn impact our testing somewhat. For our 2015 benchmark suite we began using low-level APIs when available, which in the current game suite includes Battlefield 4, Dragon Age: Inquisition, and Civilization: Beyond Earth, not counting on AMD to cease optimizing Mantle quite so soon. As a result we’re in the uncomfortable position of having to backtrack on our policies some in order to not base our recommendations on stupid settings.
Starting with this review we’re going to use low-level APIs when available, and when using them makes performance sense. That means we’re not going to use Mantle in the cases where performance has clearly regressed due to a lack of optimizations, but will use it for games where it still works as expected (which essentially comes down to Civ: BE). Ultimately everything will move to Vulkan and DirectX 12, but in the meantime we will need to be more selective about where we use Mantle.
The Drivers
For the launch of the 300/Fury series, AMD has taken an unexpected direction with their drivers. The launch driver for these parts is the Catalyst 15.15 driver, AMD’s next major driver branch which includes everything from Fiji support to WDDM 2.0 support. However in launching these parts, AMD has bifurcated their drivers; the new cards get Catalyst 15.15, the old cards get Catalyst 15.6 (driver version 14.502).
Eventually AMD will bring these cards back together in a later driver release, after they have done more extensive QA against their older cards. In the meantime it’s possible to use a modified version of Catalyst 15.15 to enable support for some of these older cards, but unsigned drivers and Windows do not get along well, and it introduces other potential issues. Otherwise considering that these new drivers do include performance improvements for existing cards, we are not especially happy with the current situation. Existing Radeon owners are essentially having performance held back from them, if only temporarily. Small tomes could be written on AMD’s driver situation – they clearly don’t have the resources to do everything they’d like to at once – but this is perhaps the most difficult situation they’ve put Radeon owners in yet.
The Test
Finally, let’s talk testing. For our benchmarking we have used AMD’s Catalyst 15.15 beta drivers for the R9 Fury X, and their Catalyst 15.5 beta drivers for all other AMD cards. Meanwhile for NVIDIA cards we are on release 352.90.
From a build standpoint we’d like to remind everyone that installing a GPU radiator in our closed cased test bed does require reconfiguring the test bed slightly; a 120mm rear exhaust fan must be removed to make room for the GPU radiator.

As an analyst , I Guarantee AMD’s Success by taking the following simple steps:1. To Stop wasting money on R&D investments altogether at once.
2. To employ a bunch of marketers like Chizow, N7, AMDesperate, . . . to Spread Rumors and bash best products of the competition, constantly.
3. To Invest saved money (R&D wasted money on new techs like HBM, Low level API Mantle, Premium water cooler, etc, etc) in Hardware Review sites to Magnify your products Strengths and the competition’s Weaknesses.
(Note: Consumers won’t judge your product against the competition in practice, They just accept what they see in Hardware Review sites & Forums)
I just gave these advices to some companies in the past, and believe me, one have the best CPU out there, and the other make the best GPU. Innovation is not an R&D’s fruth, it’s a Marketing FRUTH.
Please contact me for more details, Regards.

Astroturfing got Samsung smacked with a penalty, but a smart company would hire astroturfers who are good at disguising their bias, not obvious trolls.SanX - Sunday, July 5, 2015 - link
AMD only hope left is that company with better lithography like Samsung for example buy it entirely. You're welcome, Samsung. Hope you will not forget my as always brilliant advices.amro12 - Sunday, July 5, 2015 - link
Why no 970? 290? At least a 970, it's better than that 290x up there...Oxford Guy - Sunday, July 5, 2015 - link
Perhaps because the 970 should have been withdrawn from the market for fraud? It should have been relabeled the 965 and consumers who bought one should have been offered more than just a refund.Innokentij - Monday, July 6, 2015 - link
To be from Oxford u seem to lack logical thinking.Oxford Guy - Thursday, July 9, 2015 - link
I'm logical enough to see a comment with no substance to it.chizow - Monday, July 6, 2015 - link
Of course this is nonsense, if the 970 launched at its corrected specs, would you have a problem with its product placement? Of course not. But let's all act as if this is the first and last time a cut down ASIC is sold at a lower price:performance segment nonetheless!Oxford Guy - Thursday, July 9, 2015 - link
Your post in no way rebuts what I wrote.Hxx - Monday, July 6, 2015 - link
right because that 0.5 partition really hindered its performance lol. Lets face it , the 970 is an excellent performer with more vram than last gen nvidia's top dog (870 ti) and performing within 15% from nvidia's top tier gtx 980 for $200 less...what more there is to say?
