Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 470
IntroThe GeForce GTX 460 1GB comes with a GPU core speed of 675 MHz, and the 1024 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare those specs to the GeForce GTX 470, which comes with core speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs as well as 56 TAUs and 40 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 470, in theory, should be a bit faster than the GeForce GTX 460 1GB in general. (explain)
Texel RateThe GeForce GTX 460 1GB is just a bit (about 11%) better at AF than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 470 is a little bit (approximately 12%) better at FSAA than the GeForce GTX 460 1GB, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
