Compare any two graphics cards:
GeForce GT 315 vs GeForce GTX 460 2GB
IntroThe GeForce GT 315 features a clock speed of 625 MHz and a DDR3 memory speed of 790 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare all that to the GeForce GTX 460 2GB, which comes with a clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 460 2GB should be 356% faster than the GeForce GT 315 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 2GB will be quite a bit (about 278%) faster with regards to anisotropic filtering than the GeForce GT 315. (explain)
Pixel RateThe GeForce GTX 460 2GB is quite a bit (approximately 332%) more effective at FSAA than the GeForce GT 315, and also will be 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
