Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 4850 1GB
IntroThe GeForce 9600 GT 512MB has clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 64 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon HD 4850 1GB, which has a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4850 1GB should in theory be a little bit superior to the GeForce 9600 GT 512MB overall. (explain)
Texel RateThe Radeon HD 4850 1GB will be a small bit (about 20%) better at AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce 9600 GT 512MB should be a small bit (approximately 4%) better at FSAA than the Radeon HD 4850 1GB, and will 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
