Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 6850
IntroThe GeForce GTX 460 SE uses a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular model. It features 288 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.Compare that to the Radeon HD 6850, which comes with a core clock speed of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 960 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6850 should be 18% quicker than the GeForce GTX 460 SE in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 6850 is a small bit (approximately 19%) better at AF than the GeForce GTX 460 SE. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6850 is superior to the GeForce GTX 460 SE, though not by far. (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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of 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 clock speed of the chip. The better the texel rate, 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 amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
