Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTX 460 comes with a GPU core speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 24 ROPs.
Compare all that to the Radeon HD 6570 (OEM) 1GB, which features a GPU core clock speed of 650 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 460 should perform quite a bit faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 460 should be quite a bit (about 142%) more effective at AF than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 460 should be a lot (more or less 212%) more effective at AA than the Radeon HD 6570 (OEM) 1GB, and also will be 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: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
