Compare any two graphics cards:
GeForce GTX 570 vs Radeon HD 7870 XT
IntroThe GeForce GTX 570 uses a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory is set to run at a speed of 950 MHz on this particular model. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.Compare all of that to the Radeon HD 7870 XT, which uses a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific card. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 XT, in theory, should perform a lot faster than the GeForce GTX 570 in general. (explain)
Texel RateThe Radeon HD 7870 XT will be quite a bit (approximately 102%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7870 XT is a better choice, though only just barely. (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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
