Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 7970
IntroThe GeForce GT 340 makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this particular model. It features 96 SPUs as well as 32 TAUs and 8 ROPs.Compare all of that to the Radeon HD 7970, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7970 will be 385% quicker than the GeForce GT 340 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 7970 is quite a bit (about 573%) more effective at anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7970 is superior to the GeForce GT 340, 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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
