NVIDIA is going to retire its Kepler GPU architecture which has been supported since 2012 with the release of its R470 series drivers.

As reported by Phoronix, the NVIDIA R470 series drivers are labeled as LTSB (Long-Term Support) for the Kepler GPU series and as such, will maintain support for the said architecture for 3 years, after which it would be retired along with the GPUs. The NVIDIA Kepler GPU architecture has been supported for generations but as time goes by, older GPU architectures are removed from official support lists.
