Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 470 has a GPU clock speed of 607 MHz, and the 1280 MB of GDDR5 memory runs at 837 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 Texture Address Units, and 40 ROPs.
Compare all of that to the Radeon HD 6570 (OEM) 2GB, which has a core clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 470 will be 109% quicker than the Radeon HD 6570 (OEM) 2GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 470 should be quite a bit (approximately 118%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 470 will be much (about 367%) better at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also should 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 information (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
