Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 6770
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM works at a frequency of 902 MHz on this card. It features 192 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6770, which features a GPU core clock speed of 900 MHz, and 512 MB of GDDR5 memory set to run at 1050 MHz through a 128-bit bus. It also is made up of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 should be a little bit faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe Radeon HD 6770 will be a lot (approximately 44%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe Radeon HD 6770 will be a bit (approximately 15%) more effective at AA than the GeForce GTS 450 1GB, and capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
