Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 4750
IntroThe GeForce GT 240 GDDR5 comes with a core clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 4750, which comes with a clock frequency of 730 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 240 GDDR5 should be 6% quicker than the Radeon HD 4750 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 4750 should be much (about 33%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 4750 is a lot (approximately 165%) more effective at AA than the GeForce GT 240 GDDR5, and capable of handling higher screen resolutions while still performing well. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video 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 maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
