Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTX 460 comes with core clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 24 ROPs.
Compare that to the Radeon HD 6570 (OEM) 1GB, which features a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 460 will be 200% quicker than the Radeon HD 6570 (OEM) 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 460 should be quite a bit (about 142%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 460 is quite a bit (more or less 212%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and capable of handling higher 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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
