The AMD Radeon R9 Fury X Review: Aiming For the Top
by Ryan Smith on July 2, 2015 11:15 AM ESTOverclocking
Finally, no review of a high-end video card would be complete without a look at overclocking performance.
To get right to the point here, overclockers looking at out of the box overclocking performance are going to come away disappointed. While cooling and power delivery are overbuilt, in other respects the R9 Fury X is very locked down when it comes to overclocking. There is no voltage control at this time (even unofficial), there is no official HBM clockspeed control, and the card’s voltage profile has been finely tuned to avoid needing to supply the card with more voltage than is necessary. As a result the card has relatively little overclocking potential without voltage adjustments.
So what do we get for overclocking?
| Radeon R9 Fury X Overclocking | ||||
| Stock | Overclocked | |||
| Boost Clock | 1050Mhz | 1125MHz | ||
| Memory Clock | 1Gbps (500MHz DDR) | 1Gbps (500MHz DDR) | ||
| Max Voltage | N/A | N/A | ||
Our efforts net us 75MHz, which is actually 25MHz less than what AMD published in their reviewer’s guide. Even 100MHz would lead to artifacting in some games, requiring that we step down to a 75MHz overclock to have a safe and sustainable overclock.
The end result is that the overclocked R9 Fury X runs at 1125MHz core and 1Gbps memory, a 75MHz (7%) increase in the GPU clockspeed and 0% increase in the memory clockspeed. This puts a very narrow window on expected performance gains, as we shouldn’t exceed a 7% gain in any game, and will almost certainly come in below 7% in most games.
Our gaming benchmarks find just that. A few percent performance improvement there, a 5% improvement there. Overall we wouldn’t go as far as saying there no reason to overclock, but with such limited gains it’s hardly worth the trouble right now.
True overclocking is going to have to involve BIOS modding, a riskier and warranty-voiding strategy, but one that should be far more rewarding. With more voltage I have little doubt that R9 Fury X could clock higher, though it’s impossible to guess by how much at this time. In any case the card is certainly built for it, as the oversized cooler, high power delivery capabilities, and dual BIOS switch provide all the components necessary for such an overclocking attempt.
Meanwhile HBM is a completely different bag, and while unofficial overclocking is looking promising, as a new technology it will take some time to get a good feel for it and understand just what kind of performance improvements it can deliver. The R9 Fury X is starting out with quite a bit of memory bandwidth right off the bat (512GB/sec), so it may not be bandwidth starved as often as other cards like the R9 290X was.

@Wreckage Not quite. Cash reserves play a role in evaluating a company's net worth. When AMD acquired ATI, they spent considerable money to do so and plunged themselves into debt. The resulting valuation of AMD was not simply the combined valuations of AMD and ATI pre-acquisition. Far from it.AMD is the undisputed underdog in 2015, and has been for many years before that. That is why Ryan gave so much praise to AMD in the article. For them to even be competitive at the high end, given their resources and competition, is nothing short of impressive.
If you cannot at least acknowledge that, than your view on this product and the GPU market is completely warped. As consumers we are all better off with a Fury X in the market.

Yes, NVIDIA was definitely the underdog at the time of the AMD purchase of ATI. Many people were leaving NVIDIA for dead. NVIDIA had recently lost its ability to make chipsets for Intel processors, and after AMD bought ATI it was presumed (rightly so) that NVIDIA would no longer be able to make chipsets for AMD processors. It was thought that the discrete GPU market might dry up with fusion CPU/GPU chips taking over the market.chizow - Thursday, July 2, 2015 - link
Yep, I remember after the merger happened most AMD/ATI fans were rejoicing as they felt it would spell the end of both Nvidia and Intel, Future is Fusion and all that promise lol. Many like myself were pointing out the fact AMD overpayed for ATI and that they would collapse under the weight of all that debt given ATI's revenue and profits didn't come close to justifying the purchase price.My how things have played out completely differently! It's like the incredible shrinking company. At this point it really is in AMD and their fan's best interest if they are just bought out and broken up for scraps, at least someone with deep pockets might be able to revive some of their core products and turn things around.

Well done Mr Smith. I would go so far as to say THE best Fury X review on the internet barnone. The most important ingredient is BALANCE. Something that other reviews sorely lack.
In particular the PCPer and HardOCP articles read like they were written by the green
goblin himself and consequently suffer a MASSIVE credibility failure.
Yes Nvidia has a better performing card in the 980TI but it was refreshing to see credit
given to AMD where it was due. Only dolts and fanatical AMD haters (I'm not quite sure
what category chizow falls into, probably both and a third "Nvidia shill") would deny that
we need AMD AND Nvidia for the consumer to win.
Thanks Anandtech.

Except chizow never stated he wishes to see AMD dead.I guess it`s your butthurt talking.

Yep, just AMD fanboys ;)"What's Left of AMD" can keep making SoCs and console APUs or whatever other widgets under the umbrella of some monster conglomerate like Samsung, Qualcomm or Microsoft and I'm perfectly OK with that. Maybe I'll even buy an AMD product again.

"AMD going away won't matter to anyone but their few remaining devout fanboys'So kind (paid?) nVidia troll chizow is.

@medi03 no worries I look forward to the day (unpaid?) AMD fantroll's like you can free yourselves from the mediocrity that is AMD.chizow - Friday, July 3, 2015 - link
Yet, still 3rd rate. The overwhelming majority of the market has gone on just fine without AMD being relevant in the CPU market, and recently, the same has happened in the GPU market. AMD going away won't matter to anyone but their few remaining devout fanboys like Ranger101.piiman - Friday, July 3, 2015 - link
"AMD going away won't matter to anyone but their few remaining devout fanboys'Hmmm you'll think different when GPU prices go up up up. Competition is good for consumers and without it you will pay more, literally.
