Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 4750
IntroThe GeForce GT 240 GDDR5 1GB comes with a clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.Compare all that to the Radeon HD 4750, which features GPU core speed of 730 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also features 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 1GB is 6% quicker than the Radeon HD 4750 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 4750 will be much (about 33%) better at AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe Radeon HD 4750 should be much (more or less 165%) more effective at anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also should be able to handle higher resolutions without losing too much performance. (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 (in units of MB 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 the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
