NVIDIA R195 display driver includes new extensions to its OpenCL 1.0 conformant driver

OpenCL 1.0 Extensions: NVIDIA is the only vendor supporting OpenCL features beyond the minimum conformance level. New extensions released by NVIDIA include support for double precision, OpenGL interoperability and the new OpenCL Installable Client Device (ICD). These new features supplement existing NVIDIA-only support for 2D image, 32-bit atomics and byte addressable stores.

NVIDIA NV100 (or Fermi) is less powerful than GeForce GTX 285?

– C2050 will deliver 520 GFLOPS of IEEE 754-2008 Dual Precision format and 1.040 TFLOPS of single precision.
– C2070 stands a bit better, 630 GLOPS of Dual-Precision and 1.26 TFLOPS in Single Precision.
The single-precision numbers are the inconvenient reason why nVidia didn’t mention single-precision performance on any of the Tesla launch slides.
– EVGA’s factory overclocked GT200-based GTX 285 FTW board, packs 1.063 single-precision TFLOPS.

    Many OpenCL extensions are also available on Mac OS X for all supported compute devices, including OpenGL interop, atomics and the image functionality.
