With this new Titan performance driver, NVIDIA is enabling all or some of the performance optimizations that are usually exclusively for the Quadro lineup. This means Titan X users get a big performance boost, but a lot of businesses will still need to stick with the Quadro lineup as those cards have certified drivers.
Reddit user brutuscat2 ran SPECviewperf 12.1 on his Pascal-based Titan X video card and reports huge performance increases. In most tests, there's a performance increase ranging from 53 percent to 107 percent. Siemens NX even sees a 654 percent increase in performance! Only Maya and Showcase are showing some performance progression, perhaps due to the use of outdated versions.
Isn't it amazing what a little bit of competition can do?
