Apparently, yields are still currently lower than 50%.
A CUDA core executes a floating point or integer instruction per clock for a thread.
The GeForce GTX 480, for example, features 15 SMs of 32 cores for a total of 480.

The GeForce GTX 470 on the other hand features 14 SMs for 448 cores.
This is a key enabler for many high-performance CUDA applications.
G80 and GT200 both have 16KB of shared memory per SM.
The Fermi architecture clearly has a number of impressive design aspects and features.
Another that we are going to look at in more detail is called Nvidia 3D Vision Surround.
