Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 4730
IntroThe GeForce GT 340 has a core clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 4730, which uses a 55 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this card. It features 640(128x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4730 should be 6% quicker than the GeForce GT 340 overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 4730 is a lot (about 27%) better at anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 4730 is a better choice, and very much so. (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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
