Nvidia Volta Rumored to Feature 16GB GDDR6 with 14GB/s bandwidth
According to a new leak, the Nvidia Volta for consumers could launch around 2018. The next-gen GPU architecture is rumored to rock 16GB of GDDR6, a new standard from Micron, that will offer bandwidth up to 14GB/s.
This means Pascal refresh will span the majority of 2017 and the architecture will be based on a fine-tuned 16nm process from TSMC that would offer even higher clock speeds than the current Pascal GPUs. Rumor has it that Nvidia is planning to offer more graphics cards based on the GP102 GPU. We have already seen the partially enabled version of the graphics core that is being used in the Nvidia Titan X(P).
Additionally, most of these high-end GP102 GPUs will have Micron’s GDDR5X memory on board. Currently, products using this memory tech include the GeForce GTX 1080, Titan X (Pascal) and Tesla P40 (ECC).
As for GDDR6 inside Nvidia Volta, it is designed to ensure lower power consumption on high performance GPU boards. The GDDR6 is quite a step up on the already impressive GDDR5X, offering 16GB VRAM on 256-bit cards, that is twice the standard capacity over GTX 1080 and GTX 1070. The high-end GV102 GPU is expected to sport a 384-bit bus with 24GB of VRAM.
Volta will be fully compliant with HBM2 technology as well, however it will be reserved for special products. As of right now, it is only supported by HPC focused Pascal GP100 graphics chip. Nvidia could follow the suit with Volta and we might see HBM2 on the GV100 featuring 32-48 GB VRAM and 1~1.5 TB/s bandwidth.
As for the launch, Nvidia is expected to unveil its Volta architecture at GTC 2017 where CEO Jen-Hsun Huang is scheduled to be the inaugural keynote speaker.
