Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 6750
IntroThe GeForce GT 340 has a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 32 Texture Address Units, and 8 ROPs.Compare that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6750 will be 18% faster than the GeForce GT 340 in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 6750 should be quite a bit (more or less 48%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6750 is the winner, 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 (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
