Actually the G200 tech is based off G92. Rather than mincing words. Its better to just state what the GTS250 doesnt have in compared to GTX 260 and above.
Double Precision ((Cuda/GGPU))
Better Idle Power usage
Improved geometry shader.
Other than the architectures are basically identical. But yes they are another G92 product.
