Benchmarks Real world tests of GeForce GT 650M vs 550M

Passmark Industry standard benchmark for overall graphics card performance

Besides the above slide, NVIDIA provided some performance estimates using results from the 3DMark 11 Performance benchmark, and the results are even more heavily in favor of NVIDIA.
GeForce GT 650M | by Jarred-Walton (Apr, 2013)

3DMark 11 Graphics Industry standard benchmark that tests DirectX 11 GPU performance

3DMark Vantage Graphics Industry standard benchmark that tests DirectX 10 GPU performance

3DMark06 Industry standard benchmark that tests DirectX 9 GPU performance
