G300-Fermi Shows off Ray-Tracing and PhysX
With the Fermi architecture Nvidia more and more focuses on GPU computing and also uses those terms in their presentation. The former texture units turned into Load/Store units, the shader ALUs (which Nvidia formerly called stream processors) are Cuda core or Cuda processors now. Certainly chips basing on the Fermi architecture will be DirectX 11-compatible but Nvidia doesn't talk about that much.
A total of 512 Cuda cores will be on the G300 chip, organized in 16 SIMD units. So every SIMD has 32 ALUs which share the 16 loading and memory units (LS units, ex-TMUs). Up to now Nvidia has not revealed details about the capabilities of the LS units. The presented specifications have not given hints about the power of texture filtering yet. Values between 4 and 16 texture filters per SIMD could be possible.
