GeForce GTX 980 Ti vs 980, 680
(plus new web driver gains)

Posted July 31 2015, by rob-ART morgan, mad scientist

While we were testing the NVIDIA GeForce GTX 980 Ti, a new OS X 10.10.4 web driver was released by NVIDIA. We were so impressed with the improvements in performance over the older driver, we decided to feature results from both old and new driver while comparing it to the GTX 980 an GTX 680 Mac Edition.

Web Driver 346.02.02f03

WHAT WE LEARNED
1. In the case of Dirt 3 and Tomb Raider, the 980 Ti and 980 did not dominate the 680. In fact, the 680 won the Dirt 3 'race.'

2. OpenCL_OceanWave_Bandwidth benchmark revealed a big jump in OpenCL performance for the two Maxwell GPUs (980 and 980 Ti), thanks to the newest web driver.

3. The BruceX graph illustrates what happens when a pro app function consumes gobs of VRAM. The 980 Ti's 6GB of GDDR5 was fully utilized. Consequently, in this case, it smoked the 980 (4G) and 680 (2G).

4. NVIDIA has been busy making improvements to the custom Yosemite web drivers. We featured the apps that benefited the most from the new web driver. In addition, for the first time, we were able to run Tomb Raider and Batman: Arkham City at 5120x2880 without crashing. (NOTE: The web driver is not required for the GTX 680. The Maxwell GPUs (GTX 970, 980, 980 Ti, TITAN X, Quadro K5000) do require the web driver. The other benefit of the web driver is support for the Dell 5K display.)
