Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 6750 1GB
IntroThe GeForce 8600 GT 256MB GDDR3 has a GPU core clock speed of 540 MHz, and the 256 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 6750 1GB, which comes with clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6750 1GB should perform quite a bit faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon HD 6750 1GB is quite a bit (more or less 202%) better at AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6750 1GB is superior to the GeForce 8600 GT 256MB GDDR3, 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
