Features Key features of the GeForce GT 730 vs 630
memory bandwidth Rate at which data can be read from or stored in onboard memory
pixel rate Number of pixels a graphics card can render to the screen every second
GeForce GT 730 | by Anthony-Garreffa (Jan, 2013)NVIDIA are now listing something called the "GeForce Performance Score" which is used to define the performance of a part relative to Intel's HD4000 iGPU.
texture rate Speed at which a graphics card can perform texture mapping
GeForce GT 730 | by hassan-mujtaba (Feb, 2014)We specially qualified components and pushed factory performance tuning limits by boosting the controller speed by 50 percent and NAND bus speed 20 percent.
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
