The AMD Radeon R9 Fury X Review: Aiming For the Top
by Ryan Smith on July 2, 2015 11:15 AM ESTSynthetics
As always we’ll also take a quick look at synthetic performance. Since Fiji is based on the same GCN 1.2 architecture as Tonga (R9 285), we are not expecting too much new here.
First off we have tessellation performance. As we discussed in greater detail in our look at Fiji’s architecture, AMD has made some tessellation/geometry optimizations in GCN 1.2, and then went above and beyond that for Fiji. As a result tessellation performance on the R9 Fury X is even between than the R9 285 and the R9 290X, improving by about 33% in the case of TessMark. This is the best performing AMD product to date, besting even the R9 295X2. However AMD still won’t quite catch up to NVIDIA for the time being.
As for texture fillrates, the performance here is outstanding, though not unexpected. R9 Fury X has 256 texture units, the most of any single GPU card, and this increased texture fillrate is exactly in line with the theoretical predictions based on the increased number of texture units.
Finally, the 3DMark Vantage pixel fillrate test is not surprising, but it is none the less a solid and important outcome for AMD. Thanks to their delta frame buffer compression technology, they see the same kind of massive pixel fillrate improvements here as we saw on the R9 285 last year, and NVIDIA’s Maxwell 2 series. At this point R9 Fury X’s ROPs are pushing more than 40 billion pixels per second, a better than 2x improvement over the R9 290X despite the identical ROP count, and an important reminder of the potential impact of the combination of compression and HBM’s very high memory bandwidth. AMD’s ROPs are reaching efficiency levels simply not attainable before.

This card and the 980 ti meet two interesting milestones in my mind. First, this is the first time 1080p isn't even considered. Pretty cool to be at the point where 1080p is considered at bit of a low resolution for high end cards.Second, it's the point where we have single cards can play games at 4k, with higher graphical settings, and have better performance than a ps4. So at this point, if a ps4 is playable, than 4k gaming is playable.
It's great to see higher and higher resolutions.

Idle power does not start things off especially well for the R9 Fury X, though it’s not too poor either. The 82W at the wall is a distinct increase over NVIDIA’s latest cards, and even the R9 290X. On the other hand the R9 Fury X has to run a CLLC rather than simple fans. Further complicating factors is the fact that the card idles at 300MHz for the core, but the memory doesn’t idle at all. HBM is meant to have rather low power consumption under load versus GDDR5, but one wonders just how that compares at idle.I'd like to see you guys post power consumption numbers with power to the pump cut at idle, to answer the questions you pose. I'm pretty sure the card is competitive without the pump running (but still with the fan to have an equal comparison). If not it will give us more of an insight in what improvements AMD can give to HBM in the future with regards to power consumption. But I'd be very suprised if they haven't dealt with that during the design phase. After all, power consumption is THE defining limit for graphics performance.

Idle power consumption isn't the defining limit. The article already said that the cooler keeps the temperature low while also keeping noise levels in check. The result of keeping the temperature low is that AMD can more aggressively tune for performance per watt.Oxford Guy - Sunday, July 5, 2015 - link
This is a gaming card, not a card for casuals who spend most of their time with the GPU idling.Oxford Guy - Sunday, July 5, 2015 - link
The other point which wasn't really made in the article is that the idle noise is higher but consider how many GPUs exhaust their heat into the case. That means higher case fan noise which could cancel out the idle noise difference. This card's radiator can be set to exhaust directly out of the case.mdriftmeyer - Sunday, July 5, 2015 - link
It's an engineering card as much as it is for gaming. It's a great solid modeling card with OpenCL. The way AMD is building its driver foundation will pay off big in the next quarter.Nagorak - Monday, July 6, 2015 - link
I don't know that I agree about that. Even people who game a lot probably use their computer for other things and it sucks to be using more watts while idle. That being said, the increase is not a whole lot.Oxford Guy - Thursday, July 9, 2015 - link
Gaming is a luxury activity. People who are really concerned about power usage would, at the very least, stick with a low-wattage GPU like a 750 Ti or something and turn down the quality settings. Or, if you really want to be green, don't do 3D gaming at all.MacGyver85 - Wednesday, July 15, 2015 - link
That's not really true. I don't mind my gfx card pulling a lot of power while I'm gaming. But I want it to sip power when it's doing nothing. And since any card spends most of its time idling, idling is actually very important (if not most important) in overal (yearly) power consumption.Btw I never said that idle power consumption is the defining limit, I said power consumption is the defining limit. It's a give that any Watt you save while idling is generally a Watt of extra headroom when running at full power. The lower the baseline load the more room for actual, functional (graphics) power consumption. And as it turns out I was right in my assumption that the actual graphics card minus the cooler pump idle power consumption is competitive with nVidia's.
