Compare any two graphics cards:
Radeon HD 5870 vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5870 comes with a GPU clock speed of 850 MHz, and the 1024 MB of GDDR5 RAM runs at 1200 MHz through a 256-bit bus. It also is made up of 1600(320x5) Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which comes with a clock speed of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5870 should in theory be a lot superior to the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe Radeon HD 5870 should be much (approximately 336%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5870 should be much (approximately 423%) better at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also capable of handling 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
