Notes

• [1]
  • Dynamic shader core memory which allows an app to achieve better thread occupancy (2 virtual threads in one).
  • Flexible on-chip memory - 3 cache types now is dynamically allocated, if one type is not used - it will not be allocated.
  • fp32, fp16, int can execute in parallel.
  • Optimized for fp16.
  • Shader execution reordering.
  • In mesh shading: intermediate data from task shader now stored in the on-chip memory and accessed by mesh shader.

Features

• Hardware ray tracing.
