Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 470 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory works at a speed of 837 MHz on this model. It features 448 SPUs as well as 56 Texture Address Units and 40 Rasterization Operator Units.
Compare all that to the Radeon HD 6570 (OEM) 2GB, which comes with a clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, 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, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 470 should be quite a bit (more or less 118%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 470 should be much (more or less 367%) better at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also capable of handling higher resolutions while still performing well. (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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its 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 card's clock speed. 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
