Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 6750 1GB
IntroThe GeForce GT 240 GDDR5 1GB comes with a 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 features 96 SPUs, 32 TAUs, and 8 ROPs.Compare all that to the Radeon HD 6750 1GB, which features a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It features 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750 1GB, in theory, should perform just a bit faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe Radeon HD 6750 1GB should be quite a bit (more or less 48%) more effective at AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe Radeon HD 6750 1GB will be a lot (approximately 164%) better at AA than the GeForce GT 240 GDDR5 1GB, and should be capable of handling higher screen resolutions more effectively. (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 information (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
