Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 570
IntroThe GeForce GTX 480 has a core clock speed of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 48 Raster Operation Units.
Compare those specs to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 memory is set to run at a speed of 950 MHz on this model. It features 480 SPUs along with 60 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 480 should be a bit faster than the GeForce GTX 570 in general. (explain)
Texel RateThe GeForce GTX 570 will be a bit (approximately 5%) faster with regards to texture filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 should be a small bit (about 15%) better at FSAA than the GeForce GTX 570, and also capable of handling higher 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 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 max fill rate.
