specs:it’s a GeForce GTS 450 with a 50% increase of ROPs and memory interface
width, and overclocked for good measure. With these specifications, Nvidia
claims that the new card provides 28% higher performance than the GTS 450, with
20% more performance per watt

Zotac has card clocked at 1 GHZ core and 2GHz Shader.When we compare the new model to the GeForce GTX 460 768 MB on its way out, we
see identical render back-ends, both with a 192-bit memory interface and 24
ROPs. The similarities end there, however. The GF104 GPU in the GeForce GTX 460
is about 50% more powerful, with 336 shader cores and 56 texture units versus
the GeForce GTX 550 Ti’s 192 cores and 32 texture units. This difference is
mitigated a little by the new card’s higher clock speeds. But we still expect
the GeForce GTX 460 768 MB to outperform it by a notable margin.
