NV GF400 vs 500, difference in GL programmability?

[fred_em]

Hi,

Not sure if this is the right forum to post this question to.

What are the differences in terms of programmability (OpenGL, GLSL, and OpenCL) between a GeForce 4xx and a 5xx?

For example, one difference between a GeForce 2xx and a 4xx is OpenGL 4.x support (which I find significant, IMHO).

What are the differences between a 4xx and a 5xx?
Not interested in performance considerations.

Regards,
Fred

Both are based on the same architecture, so there is no difference in the programming model between them.
