Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon HD 6850
IntroThe Radeon HD 5750 512MB features core speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6850, which uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 960 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6850 should in theory be quite a bit faster than the Radeon HD 5750 512MB in general. (explain)
Texel RateThe Radeon HD 6850 should be much (about 48%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)
Pixel RateThe Radeon HD 6850 will be quite a bit (approximately 121%) more effective at AA than the Radeon HD 5750 512MB, and also able to handle higher screen resolutions without losing too much performance. (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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, 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 number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
