Compare any two graphics cards:
GeForce GT 310 vs Radeon HD 6970
IntroThe GeForce GT 310 features a clock speed of 589 MHz and a DDR2 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare that to the Radeon HD 6970, which makes use of a 40 nm design. AMD has clocked the core frequency at 880 MHz. The GDDR5 RAM is set to run at a frequency of 1375 MHz on this particular model. It features 1536 SPUs along with 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6970, in theory, should perform a lot faster than the GeForce GT 310 overall. (explain)
Texel RateThe Radeon HD 6970 should be a lot (about 1693%) better at texture filtering than the GeForce GT 310. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6970 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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
