Compare any two graphics cards:
GeForce GT 420 vs GeForce GTX 460 1GB
IntroThe GeForce GT 420 features a clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 48 SPUs, 8 TAUs, and 4 ROPs.Compare that to the GeForce GTX 460 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 memory works at a speed of 900 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 460 1GB should perform much faster than the GeForce GT 420 in general. (explain)
Texel RateThe GeForce GTX 460 1GB should be quite a bit (approximately 575%) faster with regards to anisotropic filtering than the GeForce GT 420. (explain)
Pixel RateThe GeForce GTX 460 1GB should be quite a bit (more or less 671%) more effective at FSAA than the GeForce GT 420, and also will be capable of handling higher resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher 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 in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
