At the Japanese edition of NVIDIAs GPU Technology Conference, NVIDIA revealed some details behind its 2016 graphics architecture, codenamed Pascal. 

The Pascal GPU is fabbed in the Taiwan Semiconductor Manufacturing Company (TSMC) based on the new 16nm FinFET process, a process that uses the popular stacking method that NAND these days uses as well. It should result in significant power savings.

Pascal will bring support for up to 32GB of HBM2 memory. Initial Pascal will launch with 16GB HBM2 memoryfrom SK.Hynix and Samsung. The 16GB HBM SDRAM (packed in four stacked 4GB HBM2 chips) will offer 1TB/s in bandwidth.

"Pascal will also be available in multi-GPU packaging, replacing the Tesla K80 (NVIDIA skipped Maxwell-gen dual-GPU Tesla). Combined figures are very interesting to compare – 24GB GDDR5 and 480GB/s bandwidth should be replaced with 32GB HBM2 and 2TB/s bandwidth, mutually connected through NVLink rather than PCIe. The NVLink will enable up to 80GB/s, which should replace PLX PCIe Gen3 bridge chips that can only support 16GB/s (8GB/s per GPU). This part should be ‘warm up’ for 2018 and the Volta architecture".
