Dual GPU Battle: GTX 980 Ti SLI vs. Radeon R9 Fury X Crossfire

Posted by Soulskill on from the for-when-$1k-seems-like-a-reasonable-amount-to-spend-on-graphics dept.

jjslash writes: High-end GPU parts from Nvidia and AMD are plenty fast, these days. While top-end cards from both can provide playable performance at 4K, many games dip down to and below 30fps. Folks looking to achieve smooth 4K gameplay will undoubtedly be eyeing dual GTX 980 Ti or Fury X cards to realize their PC gaming machine's full potential. TechSpot puts both cards to the test in SLI and Crossfire modes, at stock and overclocked speeds in over 10 games to see who gets the bragging rights. As it turns out, AMD has a tiny advantage in average frame rates. The two split wins on frame time, but AMD won by bigger margins. When the cards get overclocked, Nvidia is the clear winner, and power consumption favors Nvidia as well.

    4k is cool and all, I get it. Still, why would I want my PC to render 4k at suboptimal frame rates, when I can play at full HD and have the display present me those 1080px in a way no native HD display could do? Really, I want one of those things just for the real estate and the freedom to place more better looking windows where I want and need them, but for gaming at native resolution, I just don't get it.

      Okay, let's pretend 4k monitors didn't exist (they do). I give you another reason, supersampled anti-aliasing where you render at a higher resolution, apply any effects and maybe fxaa and then downscale the frame at the end to native resolution. Basically the downscaling the final frame is the best form of anti-aliasing one can actually have due to how downscaling algorithms derive pixel values from multiple sources pixels.

      Having used a 55" 4K 60Hz panel (Sony 55X9005A) as my gaming display since 2013, I can say that high resolution gaming is pretty much the same thing as high refresh rate gaming or VR gaming: you won't "get it" until you try it.

      Furthermore, in my time I've observed three primary types of gamers:

      • "graphics & performance don't matter" gamers
      • "resolution & fidelity is everything" gamers
      • "fps & low latency is everything" gamers

      If you're not in category 2 then I'm afraid you'll never "get" these very expensive high end products/builds nor do you need to.

      People who are a balanced combination of categories 2 and 3 are the populous target audience of Asus, MSI, Alienware, etc etc and those people keep those companies afloat. It's not the high end customers who are interested in dual GPU setups or 4K at this time.

      On a 4K display, antialiasing is already completely pointless. It's uses a huge amount of rendering horsepower for a blur effect that is impossible to notice without A/B comparisons. Competent system testers use it in benchmarks only to put more load on the systems, and incompetent ones to prove that SLI/CF builds are inadequate for 4K. Popular but incompetent review sites like IGN like to do that latter part regularly, which is really counterproductive because it only increases FUD and slows down 4K adoption.

      Personally, I've been running games in 4K without antialising since 2013. First with an overclocked GTX 660 which required lowering the fidelity settings of new games. Afterwards, with a single GTX 980 which could run every game on maxed settings. About 6 months ago I built a GTX 980 SLI rig which could handle some useless antialising too, but instead I elect to put the cards in powersave mode which makes the rig quiet while gaming.

      Disclaimer: 4K particularly on maxed settings will require you to forget about "stable 60fps" because high end graphics settings like that cause framerate drops unrelated to raw GPU performance.

      Not all games are about competitive FPS, it's that simple really. If you're playing The Witcher, Metro: Last Light, Tomb Raider, Civilization or any of a bunch of other games you just want it to be smooth and otherwise crank up the resolution/details/effects as far as you can.

      Hate to break it to you, but you're lacking fidelity, because the X900 Sonys do not support HDMI 2.0a (18gbps), required for true RGB at 60fps. And the X900 does not have DisplayPort.

      Instead, you're using YUV422 format, which is a way to cheat and get 60fps 4K using standard HDMI 1.4a signalling and speeds.

      Even the flagship of 2014, the X950 series does not support 4K at 60 at RGB or YUV444.

      True HDMI 2.0 sets and equipment are coming out this year (HDMI 2.0 was ratified last year), these support 18gbps signalling and thus will get you your 4k @ 60 at full bit-depth.

    "X is better than Y for the use cases I'm seeing" is a perfectly valid argument. Now, it's best to clarify as such, and not simply extrapolate out to every single possible use under the sun, a la "Well, Nvidia/AMD gets 3 more frames per second on $GAME, so therefore it's better for EVERYTHING." That's stupid - but something like my recent experience where I had major crash problems with AMD drivers on some of the games I like to play, and none with Nvidia (one desktop, the other laptop), I'm strongly inclined to go with Nvidia on my next major purchase, because I have a very visceral (if anecdotal) sense that one is going to work better for what I'm using it for than the other.
