This is proof that the 8800GT only has 92 shader units. Proof:

1. The 8800Ultra is ~20% faster than the 8800GT.
2. Assuming 112 shader units for 8800GT, the 8800Ultra would only have a 14% functional unit lead.
3. The 8800GT has a faster clock speed than the 8800Ultra, which should DECREASE the lead for the 8800Ultra.
4. Therefore, 8800GT can not possibly have 112 shaders. The only other choice is 96 shaders.
