Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 4730
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 memory works at a frequency of 790 MHz on this particular model. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon HD 4730, which features a core clock frequency of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4730 should be quite a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe Radeon HD 4730 should be much (about 73%) faster with regards to AF than the GeForce GT 320. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4730 is superior to the GeForce GT 320, 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 information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
