Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 5770
IntroThe GeForce 8600 GT 512MB DDR2 features a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare those specifications to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5770 is 500% faster than the GeForce 8600 GT 512MB DDR2 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5770 will be a lot (approximately 294%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5770 is the winner, by a large margin. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
