Compare any two graphics cards:
GeForce GT 420 vs GeForce GTX 960
IntroThe GeForce GT 420 uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 48 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.Compare that to the GeForce GTX 960, which has core clock speeds of 1127 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 960 is 289% quicker than the GeForce GT 420 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 960 is quite a bit (about 1188%) better at texture filtering than the GeForce GT 420. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce GT 420, and very much so. (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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at 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 can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
