Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 6850
IntroThe GeForce GT 320 comes with a GPU core clock speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 790 MHz through a 128-bit bus. It also is comprised of 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6850, which has a clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 960 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6850 should perform a lot faster than the GeForce GT 320 in general. (explain)
Texel RateThe Radeon HD 6850 will be quite a bit (about 187%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)
Pixel RateThe Radeon HD 6850 should be quite a bit (about 474%) better at FSAA than the GeForce GT 320, and also should be capable of handling higher 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 information (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
