Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5870
IntroThe GeForce GTS 450 1GB comes with a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 RAM is set to run at 902 MHz through a 128-bit bus. It also is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 5870, which comes with GPU clock speed of 850 MHz, and 1024 MB of GDDR5 memory running at 1200 MHz through a 256-bit bus. It also features 1600(320x5) SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5870 should be quite a bit faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe Radeon HD 5870 will be quite a bit (approximately 171%) better at texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5870 is a better choice, 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. 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 memory bandwidth, the better 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
