Overclocking

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.

OC: Battlefield 4 - 3840x2160 - Ultra Quality - 0x MSAA

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.

    @piiman - I guess we'll see soon enough, I'm confident it won't make any difference given GPU prices have gone up and up anyways. If anything we may see price stabilization as we've seen in the CPU industry.

    Another portion of bulshit from nVidia troll.

    AMD never ever had more than 25% of CPU share. Doom to Intel, my ass.
    Even in Prescott times Intell was selling more CPUs and for higher price.
  • chizow - Monday, July 6, 2015 - link

    @medi03 AMD was up to 30% a few times and they did certainly have performance leadership at the time of K8 but of course they wanted to charge anyone for the privilege. Higher price? No, $450 for entry level Athlon 64, much more than what they charged in the past and certainly much more than Intel was charging at the time going up to $1500 on the high end with their FX chips.

    Best interest? Broken up for scraps? You do realize how important AMD is to people who are Intel\NVidia fans right?

    Without AMD, Intel and NVidia are unchallenged, and we'll be back to paying $250 for a low-end video card and $300 for a mid-range CPU. There would be no GTX 750's or Pentium G3258's in the <$100 tier.

    @Samus, they're irrelevant in the CPU market and have been for years, and yet amazingly, prices are as low as ever since Intel began dominating AMD in performance when they launched Core 2. Since then I've upgraded 5x and have not paid more than $300 for a high-end Intel CPU. How does this happen without competition from AMD as you claim? Oh right, because Intel is still competing with itself and needs to provide enough improvement in order to entice me to buy another one of their products and "upgrade".

    The exact same thing will happen in the GPU sector, with or without AMD. Not worried at all, in fact I'm looking forward to the day a company with deep pockets buys out AMD and reinvigorates their products, I may actually have a reason to buy AMD (or whatever it is called after being bought out) again!

    you overestimate the human drive... if another isn't pushing us, we will get lazy and that's not an argument... what we'll do instead to make people upgrade is release products in steps planned out much further into the future that are even smaller steps than how intel is releasing now

    I think this chart shows a better view of who was the underdog and when:

    http://i59.tinypic.com/5uk3e9.jpg

    ATi were ahead for the 9xxx series, and that's it. Moreover, NVIDIA's chipset struggles with Intel were in 2009 and settled in early 2011, something that would've benefitted NVIDIA far more than Intel's settlement with AMD as it would've done far less damage to NVIDIA's financials over a much shorter period of time.

    The lack of higher end APUs hasn't helped, nor has the issue with actually trying to get a GPU onto a CPU die in the first place. Remember that when Intel tried it with Clarkdale/Arrandale, the graphics and IMC were 45nm, sitting alongside everything else which was 32nm.

    I think you have to look at a bigger sample than that, riding on the 9000 series momentum, AMD was competitive for years with a near 50/50 share through the X800/X1900 series. And then G80/R600 happened and they never really recovered. There was a minor blip with Cypress vs. Fermi where AMD got close again but Nvidia quickly righted things with GF106 and GF110 (GTX 570/580).
  • Scali - Tuesday, July 7, 2015 - link

    nVidia wasn't the underdog in terms of technology. nVidia was the choice of gamers. ATi was big because they had been around since the early days of CGA and Hercules, and had lots of OEM contracts.
    In terms of technology and performance, ATi was always struggling to keep up with nVidia, and they didn't reach parity until the Radeon 8500/9700-era, even though nVidia was the newcomer and ATi had been active in the PC market since the mid-80s.

    Well done analysis, though the kick in the head was Bulldozer and it's utter failure. Core 2 wasn't really AMD's downfall so much as Core/Sandy Bridge, which came at the exact wrong time for the utter failure of Bulldozer. This combined with AMD's dismal failure to market its graphics card has cost them billions. Even this article calls the 290x problematic, a card that offered the same performance as the original Titan at a fraction of the price. Based on empirical data the 290/x should have been almost continuously sold until the introduction of Nvidia's Maxwell architecture.

    Instead people continued to buy the much less performant per dollar Nvidia cards and/or waited for "the good GPU company" to put out their new architecture. AMD's performance in marketing has been utterly appalling at the same time Nvidia's has been extremely tight. Whether that will, or even can, change next year remains to be seen.
