(Rumor) New Nvidia Volta Cards To Use GDDR6 & HBM2 Memory
Rumors have been floating around for a few days that Nvidia will be releasing a new series of GPUs this year based on the Volta architecture. The Nvidia Volta would be based on a 12-nanometer FinFET process developed by Taiwan Semiconductor Manufacturing (TSMC) and would likely utilize GDDR6 & HBM2 memory, giving it an enormous boost in performance compared to the existing Pascal family. GDDR6 is far from ready and not much information can be found on the architecture. Considering that existing GDDR5X memory (seen in the GTX 1080/Titan X) is rated at 10Gbps, GDDR6 chips will get a 60% boost in memory bandwidth by being rated at 16Gbps.
The news was first broken by Fox Business, which also reported that the very first Nvidia Volta cards would be used in supercomputers and that consumers are not particularly likely to be able to use them for quite some time. TSMC has been a little close-lipped about the exact gains in performance their new process will bring, but the company has gained the exclusive rights to produce these cards for Nvidia. This could mean that the Taiwanese corporation may win back some of Nvidia’s business from Samsung.
The current Pascal generation is still being manufactured on 16-nanometer FinFET and will likely remain the mainstay GPU for regular users for the foreseeable future. Nvidia has floated a few balloons that the company will be rolling out a new family of GPUs (their rumored Pascal refresh line) this year based on the older FinFET process and will likely be referred to as the 2000 series. This would probably include an overclocked version of Nvidia’s current flagship, the GeForce GTX Titan, and would give a significant boost in performance thanks to having more cores.
The Nvidia Volta’s boost in performance would mainly come from the improved architecture, though it remains to be seen if the Volta will even launch this year. Even for Nvidia, a launch so soon after Pascal was made commercially available would be rather soon, so it could very well not happen until 2018 or later. Then again, most common users will probably be more than happy with the current generation of GPUs, not to mention the upcoming 2000 series.
