Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon HD 6850
IntroThe GeForce 8600 GT 512MB GDDR3 comes with a core clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also features a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 6850, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is made up of 960 SPUs, 48 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6850 should in theory be much better than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe Radeon HD 6850 will be quite a bit (approximately 331%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe Radeon HD 6850 will be quite a bit (more or less 474%) more effective at anti-aliasing than the GeForce 8600 GT 512MB GDDR3, and also 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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 rate is also dependant on many 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.
