Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 580
IntroThe GeForce GTX 570 features a clock frequency of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also features a 320-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.
Compare all of that to the GeForce GTX 580, which has a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 580 should be a lot faster than the GeForce GTX 570 overall. (explain)
Texel RateThe GeForce GTX 580 should be a little bit (approximately 12%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 580 will be quite a bit (approximately 27%) more effective at AA than the GeForce GTX 570, and will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
