Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 4850 512MB
IntroThe GeForce GTX 460 SE has a clock speed of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 4850 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 RAM runs at a frequency of 993 MHz on this specific model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 460 SE is 71% faster than the Radeon HD 4850 512MB overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 460 SE should be a lot (approximately 25%) faster with regards to AF than the Radeon HD 4850 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 4850 512MB, and very much so. (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 max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
