Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 4650 1GB
IntroThe GeForce 8600 GT 512MB DDR2 features a clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specifications to the Radeon HD 4650 1GB, which comes with a clock speed of 600 MHz and a GDDR3 memory speed of 700 MHz. It also features a 128-bit memory bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4650 1GB should theoretically be much faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Radeon HD 4650 1GB is a lot (more or less 122%) faster with regards to AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon HD 4650 1GB should be a bit (more or less 11%) more effective at anti-aliasing than the GeForce 8600 GT 512MB DDR2, and should be capable of handling higher resolutions better. (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 (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
