Features Key features of the GeForce GTX 460  vs GT 630 

memory bandwidth Rate at which data can be read from or stored in onboard memory

GeForce GTX 460
108.8 GB/s
GeForce GT 630
51.2 GB/s
In return for this decrease in performance, the GTX 460 SE features 1 GB memory which means that the full memory controller is used resulting in higher bandwidth for the GPU of the GTX 460 SE.

pixel rate Number of pixels a graphics card can render to the screen every second

GeForce GTX 460
9.1 GPixel/s
GeForce GT 630
3.24 GPixel/s
You may combine up to two GTX 460 SE cards in SLI for better performance or improved image quality settings.

texture rate Speed at which a graphics card can perform texture mapping

GeForce GTX 460
36.4 GTexel/s
GeForce GT 630
13 GTexel/s
You may combine up to two GTX 460 cards in SLI for added performance or improved image quality settings.

floating point performance How fast the gpu can crunch numbers

GeForce GTX 460
873.6 GFLOPS
GeForce GT 630
311 GFLOPS

shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading

Due to a bug in GPU-Z the shaders are reported incorrectly as 224, the correct number is 336.
