NVIDIA has officially introduced (paper-launch) the first gaming GeForce based on the new Pascal GP104 GPU architecture: the GeForce GTX 1080 and GTX 1070. Few weeks ago, NVIDIA introduced the GP100 GPU with the Tesla P100 compute card. The GP100 GPU is the full version of the Pascal architecture while the GP104 is a cut down version for gaming cards.
new Pascal architecture built on TSCM 16nm FinFET.
GPU Boost 3.0 that brings more functionnalities than previous GPU Boost 2.0.
first card to support new GDDR5X graphics memory. The Pascal GPU GP104 supports both new GDDR5X and old GDDR5 memory. Cheaper cards like the GTX 1070 will have GDDR5 memory modules.
FP32 performance: 8.9 TFLOPS (boost clock).
The GTX 1080 should be 20% faster than the GTX 980 Ti.
FP32 performance: 6.5 TFLOPS (boost clock).
The GeForce GTX 1080 will be launched on May 27 2016 with a recommended price of USD $599 while the GTX 1070 will be launched on June 10 2016 with a recommended price of USD $379.
This screenshot from 4gamer.net shows the CUDA support level of the GTX 1080. (the GP104 supports CUDA compute capability 6.1).
So i guess no HBM for Nvidia right?
HBM2 seems to be reserved for the full Pascal GPU, the GP100: http://www.geeks3d.com/20160405/gtc-2016-nvidia-pascal-gp100-gpu-and-tesla-p100-computing-platform-announced/. Maybe a GeForce based on the full GP100 like a GTX 1080 Ti could be available with HBM2.
GP104 is Compute Capability 6.1.
Pascal GPU family is the world’s first discrete GPU family to support HEVC Main12 hardware decoding, improved from GM206(GTX 960/GTX 950)’s Main10/Main hardware decoder.
VP9 hardware decoding also supported like GM206(GTX 960/GTX 950).
