TITAN X vs. 290X CrossFire vs. GTX 980 SLI
#1
CLICK HERE TO SEE THIS POST ON THE MAIN SITE
We are using 33 games to benchmark the performance of three top single-GPU video cards which represent the fastest from AMD and from Nvidia - the GTX TITAN X, the GTX 980, and the R9 290X.  We have already tested them before at stock and overclocked, but never before using TITAN X versus 290X CrossFire and against GTX 980 SLI. The TITAN X is in a class by itself as it is the only card with 12GB of vRAM which allows it to play with some AA and maxed-out settings, even up to 4K resolutions. In our earlier testing, the GTX 980 won decisively over the 290X, but we only tested up to 2560x1600 resolution.  Now we'd like to also see how GTX 980 SLI and non-throttling R9 290X CrossFire performance compare with each other and also with the stock and the overclocked GTX TITAN X.

Since we have two reference versions of the 290X - a very capable PowerColor overclocked PCS+ card and a recent VisionTek 290X - we are going to need to run them each with their fans running at 100% to prevent throttling when they are in CrossFire.  The GTX 980 and SLI is tested at stock, while the GTX TITAN X is benched at both stock and also at moderately overclocked speeds.

Untitled-4The GTX TITAN X is the undisputed king of single-GPU performance.  However, performance comes at a premium as it costs $1000.  What we want to find out is if a $600 pair of R9 290Xes in CrossFire (or even GTX 980 SLI for $1100), can deliver the same or a similar experience as a single TITAN X.

AMD’s R9 290X are generally priced beginning from $299 to well over $400, sometimes with a rebate, and often bundled with DiRT Rally at Newegg.com.  The overclocked versions are generally clocked from 1030MHz to 1050MHz on the core, up 30MHz to 50MHz over reference, same as our PowerColor clocked PCS+ 290X.  At the time of writing, not one reference version of the 290X is available at Newegg.  The GTX 980 and GTX 970 are both now bundled at participating etailers with the Witcher 3: Wild Hunt and with Batman: Arkham Knight.

The Myth of the Throttling Reference 290X & the lack of a proper CrossFire Solution


The reference versions are evidently quite unpopular, originally getting a bad reputation for running hot and throttling well below AMD’s “up to 1000MHz” on the core when it first launched.  We were quite fortunate to get a PowerColor PCS+ overclocked reference version of the 290X at launch from retail that is clocked at 1030MHz on the core, and it does not throttle in cool ambient temperatures.  And in testing our recently purchased VisionTek reference version which also pegs 1000MHz, we find it does not throttle either at stock Uber (55%) fan profile. Neither card throttles at all - either separately or in CrossFire with a space between them - when their cooling fans are set to a nearly unbearably noisy 100%.

r9 290x0C 300x183 PowerColor R9 290X OC vs GTX 780 Ti   the overclocking gloves come off!Evidently the early Hawaii GPUs at their launch barely met specifications as the reference cooler was unable to cool them properly without throttling the clock speeds.  At Hawaii's launch, AMD was determined to beat the original TITAN’s performance even if it meant running the 290X on the edge with the Uber clocks and uber noise.

Newer Hawaii GPUs evidently have no such issues with the reference cooler as long as the gamer is willing to put up with what most consider excessive noise from a fan that spins up to 55% when the GPU hits 95C.  This is a rather big issue that CrossFire users face when picking a 290/X video card – either use reference and put up with extreme noise from two cards, or use an open design for two hot-running cards and roast the interior of your case and the PC hardware inside.  Of course, the ideal solution is to use water to cool two hot-running Hawaii GPUs, but even a highly overclocked watercooled R9 290X will not catch a less expensive aftermarket air cooled GTX 980 in performance.

The R9 290X vs. the GTX 980 & vs. the GTX TITAN X


The VisionTek reference version of the R9 290X is clocked up to 1000MHz while the PowerColor 290X OC Edition is clocked up to 1030MHz .  Memory clocks are 1250MHz at stock GDDR5 5000 speeds.  When we ran them together in CrossFire, both GPU speeds are normalized so that they both peg at 1000MHz.  Also, PowerDraw set up +50%, and the fans are set to 100% using the latest version of MSI's Afterburner.   We could tell that there was no throttling since we had very uniform results across all of the runs over long benching sessions.

100_8402The reference GTX 980 and TITAN X were left at stock clocks and fan profile although we maxed out the PowerDraw and set the thermals to 94C using EVGA's PrecisionX.

What about overclocking?

Both of our evaluation samples of the reference GTX 980 overclock well on stock fan profile and stock voltage so that they performs significantly faster than our mildly overclocked PowerColor R9 290X which can only reach 1050MHz together in CrossFire.   Hawaii does not overclock particularly well on air, so we only overclocked TITAN X.  We are able to add +200MHz offset to the core and +200MHz to the memory.

100_8553Since we do not want any chance of our CPU bottlenecking our graphics, we are testing all of our graphics cards by using our Intel Core i7-4770K at 4.0GHz, 16 GB Kingston "Beast" HyperX DDR3 at 2133MHz, and an ECS Golden Z87 SLI/Crossfire motherboard. The Core i7-4770K at 4.0GHz is fast enough to differentiate even high-end video cards at high resolution and at high detail settings.

Before we look at our test bed and run benchmarks, let's check out test configuration.

GTA5This is the last time that we are benching at 2560x1600.  We will use the more popular 2560x1440 beginning this weekend with our next review that will feature the brand new driver released today, WHQL 352.86 and the Witcher 3 released tomorrow.

Let's head to the performance charts to see how a non-throttling pair of 290Xes in CrossFire compares with the stock and overclocked TITAN X, as well as versus GTX 980 SLI both stock and overclocked.  We will also give single GTX 980 versus 290X results.


Performance summary


Following are two summary charts of 33 modern PC games and 2 synthetic benches. The highest settings are generally chosen and it is DX11 when there is a choice; DX10 is picked above DX9, and the settings are generally ultra or maxed unless specified on the chart. Specific settings are listed on the charts. The benches are run at 1920x1080, 2560x1600 and 3840x2160.  Except for FireStrike and 3DMark 11, the results are given for average frame rates per second.

The first column shows the performance of the stock 290X compared with 290X CrossFire scaling in the second column.  The third column represents the TITAN X at its stock clocks, and then in the 4th column, overclocked (+200MHz Core/+200MHz memory).  The stock GTX 980 SLI is represented in the 5th column compared with the GTX 980 in the last column to demonstrate SLI scaling.

main-cht

What we can take away from this rather large performance evaluation is that there is nothing in multi-GPU to compare with a TITAN X single GPU experience.  First of all, if you are going to play at 4K and demand AA and details, the TITAN X' 12GB of vRAM can certainly be useful as several games - Wolfenstein: The Old Blood, Max Payne 3, and perhaps GTA V at some detail settings - do not run well or at all with 4GB of vRAM.  Secondly, there is the issue of smoothness, and the TITAN X delivers better than with any multi-GPU solution even though they may have higher frame rates.

We ran with AMD's frame pacing on for CrossFire. Even though we may have technically lost a little performance, we received a smoother experience with less hitching - for example, in GRiD: Autosport, we got 99.2 fps average with Frame Pacing on with slightly smoother visuals versus 101.6 fps average with it off.  However, we also noticed in a few games (for example with Shadows of Mordor, GTA V and with Project CARS) that there was noticeable hitching and lack of smooth delivery with 290X CrossFire compared with a single 290X.

Although 290X strengths become much more apparent as the resolution increases to 4K, and Frame Pacing has been improved, there are still some CrossFire issues. We noted, as  especially with Far Cry 4 that there is a noticeable and visual lack of smoothness with 290X CrossFire, and that the frame rate is more than double a single card's rate.  AMD also appears to have some issues with the very latest games that will hopefully be addressed by later drivers and game patches.  Nvidia's GTX 980 SLI delivers a faster overall experience that is smoother on more stable drivers with the latest games.

Let's wrap it up.

Conclusion


This has been quite an interesting exploration for us in evaluating R9 290X CrossFire versus GTX 980, and versus the stock and overclocked GTX TITAN.  The 290X and 290X CrossFire did well performance-wise, especially at 4K, but it definitely slots below the GTX 980 GTX 980 SLI.  From looking at performance, the 290X appears to be sit well at $350 compared to the GTX 980 considering the issues a gamer has to put up in extra noise and heat, along with driver issues with the newest games.  AMD currently has one game bundled with its 290X while the GTX 980 comes with two, and the TITAN X has no game bundle at all.  Of course, the direct competitor and price alternative to the 290X is the GTX 970 which also comes with a two game bundle.

If money is not an object, the TITAN X is our first choice for high performance gaming.  Although stock GTX 980 SLI is faster generally than an overclocked TITAN X, and GTX 980 SLI can be further overclocked, we personally prefer the TITAN X experience for everything considered.  And as a low-priced alternative, 290X CrossFire is a very strong performer at 4K resolutions, if one is willing to put up with the extra heat and especially the noise, while waiting for AMD to generally optimize drivers for the very newest games that they do not sponsor.


The Conclusion:


  • The GTX TITAN X is the best performing single-GPU card, followed by the GTX 980.  However, the TITAN X experience comes at a steep price premium.
Stay tuned, there is a lot coming from us at BTR. You can expect a new WHQL driver performance evaluation featuring the Witcher 3: Wild Hunt this week as it will become BTR's latest benchmark!  We are also working on our HyperX Cloud Headset review.  AND ...  We will give away a free copy the Witcher 3: Wild hunt tomorrow to a lucky BTR forum member.

Happy Gaming!

I'm shocked to see the Titan x outperforming 290x crossfire. Very impressive.

Quite impressive.  And it makes no sense to me that Nvidia will release something faster than Titan X for less money (i.e. GTX 980 Ti).  However, maybe a Ti that is a little slower than Titan X to compete with 390X on price and performance.

If you notice that PC does NOT say "the world's fastest single GPU Video card" - which they would claim if they could.
-- rather it is "most advanced" with HBM and probably slower than the TITAN X overall as we are expecting (not what the Advocates are expecting)

It seems to me that AMD may be returning to the 2900XT versus the 8800-GTS style of positioning instead of against the top GTX.  Their new CEO appears to be less aggressive and more pragmatic than Read.  AMD will play the HBM and "value" card is my prediction.  Nvidia should be ready for this strategy having had months and months and months to prepare for it.
