GPU Caps Viewer
 

A new version of GPU Caps Viewer is out! The main new feature of this version is the support of GeForce GTX 480 and GTX 470.
GPU Caps can now display the TDP (thermal design power) and the number of SMs (streaming multiprocessors – NVIDIA GeForce) or SIMD engines (AMD / ATI Radeon).
I also fixed a bug in the surface deformer OpenCL demo.
And if you have an OpenGL 4.0 driver like this Catalyst 10.3, you can display some OpenGL 4.0 data…
