Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 4850 2GB
IntroThe GeForce 9600 GT 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this card. It features 64 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 4850 2GB, which has a core clock frequency of 625 MHz and a GDDR4 memory speed of 993 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 2GB should be 10% quicker than the GeForce 9600 GT 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 4850 2GB will be a bit (approximately 20%) better at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe GeForce 9600 GT 1GB should be a small bit (about 4%) faster with regards to anti-aliasing than the Radeon HD 4850 2GB, and also will be capable of handling higher resolutions without losing too much performance. (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 (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This 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 processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
