Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 4730
IntroThe GeForce GT 340 uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this card. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon HD 4730, which comes with GPU core speed of 700 MHz, and 512 MB of GDDR5 RAM running at 900 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4730 should in theory be a bit faster than the GeForce GT 340 in general. (explain)
Texel RateThe Radeon HD 4730 should be quite a bit (more or less 27%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4730 is the winner, by far. (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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of 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.
