Compare any two graphics cards:
GeForce GT 130 vs GeForce GTX 750
IntroThe GeForce GT 130 features a GPU clock speed of 500 MHz, and the 768 MB of DDR2 memory runs at 250 MHz through a 192-bit bus. It also is comprised of 48 Stream Processors, 24 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the GeForce GTX 750, which features a clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 750 should perform a lot faster than the GeForce GT 130 in general. (explain)
Texel RateThe GeForce GTX 750 will be much (approximately 172%) better at anisotropic filtering than the GeForce GT 130. (explain)
Pixel RateThe GeForce GTX 750 is much (about 104%) more effective at FSAA than the GeForce GT 130, and also able to handle higher screen resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
