NVIDIA GeForce GTX 980 Ti Review


NVIDIA GeForce GTX 980 Ti Testing:

Finding out the amount of FPS performance delivered by the NVIDIA GeForce GTX 980 Ti will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will be testing the cards at their stock speeds to see how they stack up and will test each one to find the maximum stable overclock. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. Resolutions of 1920 x 1080, 2560 x 1440, and 3840 x 2160 will be used.

  • NVIDIA GeForce GTX 980 Ti:  Core 1455MHz,  Memory 1951MHz


Much like with the GTX Titan X, NVIDIA has stated that it has seen GTX 980 Ti samples scaling up into the 1400MHz Boost clock range on the GPU core. As I saw when I looked at the Titan X, this really is not too far out of the ballpark, as the Titan X hit a consistent Boost clock speed just shy of 1420MHz in my testing on the sample I have. That being said, the GTX 980 Ti delivers a bit more overhead on the sample I have running at a consistent Turbo Boost clock speed of 1455MHz. It fluctuates higher depending on the load, but 1455MHz is the low end of the range. To reach that clock speed I did have to crank on the voltage a bit harder than on the GTX Titan X, driving up the power penalty a bit.

Equipped with GDDR5 memory rated for operation at an effective data rate of 7Gbps or 1752MHz, this is your starting point on the road to overclocking the 6GB of GDDR5 on the GTX 980 Ti. I have seen some cards with memory clocks creeping up over the 8Gbps range, but it really comes down to the luck of the draw and how much voltage it will take to get there. That being said, 1950MHz+/- is right in the range for many of the latest NVIDIA cards I have tested.

Wringing out the overclocking margin on the GTX 980 Ti consisted of using the latest version of EVGA's Precision overclocking and tuning utility to manage the core clock speed, memory speed, thermal and power limits, additional voltage, and fan speeds. NVIDIA's GTX 980 Ti has a base core clock speed of 1000MHz on the core, with a Boost clock speed of 1075MHz. Seeing that just about every Maxwell-based card I have tested has delivered a Boost clock speed of over 1400MHz, I felt that was a reasonable point to start at. I pushed the core clock peed up to +200MHz and promptly had a failure in my Unigine 4.0 testing. That was a bit too low for a failure, so I bumped the voltage up in Precision to +56mV and re-ran the test. Now we were cooking with grease. I kept pushing 20MHz at a time and hit a failure at +260MHz on the core. Backing down by 10MHz did not help, so I had to push the core clock speed back down to +240MHz and the GTX 980 Ti easily cranked out improved results with a final Boost clock speed that fluctuated between 1455MHz and 1467MHz depending on the load.

The memory speed was a bit easier to nail down. I pushed the memory speed slider up to +400MHz and the card performed just fine. At +420MHz it would fail to deliver clear screen images and crash, leaving the memory clock speed at a maximum of 1951MHz. Really not too shabby when you get down to it. When overclocked the GTX 980 Ti easily out performs the GTX Titan X at stock speeds thanks to the great overclocking seen on the card. What you can get for your time commitment, if your sample is close to mine, is +380MHz on the core and +200MHz on the GDDR5 memory. Not too bad for some tinkering around time.



Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for thirty minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were re-run until they passed a full hour of testing.
