Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 4850 2GB
IntroThe GeForce 9600 GT 512MB has a core clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare that to the Radeon HD 4850 2GB, which features a GPU core clock speed of 625 MHz, and 2048 MB of GDDR4 memory set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 2GB should perform a small bit faster than the GeForce 9600 GT 512MB overall. (explain)
Texel RateThe Radeon HD 4850 2GB should be a bit (more or less 20%) faster with regards to anisotropic filtering than the GeForce 9600 GT 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 9600 GT 512MB is the winner, but only just. (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 information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
