Recently at the GTC (GPU Technology Conference) event which is currently being held in Japan, NVIDIA showed off its next generation graphics core which is named as Pascal, coming in Q1 or Q2 of 2016.
Pascal will be perhaps the first GPU lineup based onthe 16nm process node, making it more efficient and NVIDIA’s first GPU lineup based on High Bandwidth Memory 2 (HBM 2), a new type of memory with much more bandwidth than the GDDR5. Previously at the GTC March, 2015, we heard a lot from NVIDIA about Pascal based architecture, but a few changes and improvements are noticed as compared with previous one.
The board of Pascal based GPU looks like AMD’s recent Fiji based GPUs, but with a different size. The Fury X was a bit smaller in looks as compared to this one. However, we are yet to see the detailed image of this GPU line up. The GPU comprises of four HBM2 stacks and comes with the memory of up to 16GB with HBM2 for GeForce consumers while up to 32GB with HBM2 for professional level. According to the report, the new GP100 chip will feature the following;
- Pascal micro architecture.
- DirectX 12 feature level 12_1 or higher.
- Successor to the GM200 GPU found in the GTX Titan X and GTX 980 Ti.
- Built on the 16FF+ manufacturing process from TSMC.
- Allegedly has a total of 17 billion transistors, more than twice that of GM200.
- Taped out in June 2015.
- Will feature four 4-Hi HBM2 stacks, for a total of 16GB of VRAM for the consumer variant and 32GB for the professional variant.
- Features a 4096bit memory interface.
- Features NVLink and support for Mixed Precision FP16 compute tasks at twice the rate of FP32 and full FP64 support. 2016 release.
