Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 4770
IntroThe GeForce GT 240 GDDR5 1GB uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 4770, which has GPU core speed of 750 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 240 GDDR5 1GB should in theory be a small bit better than the Radeon HD 4770 overall. (explain)
Texel RateThe Radeon HD 4770 is quite a bit (approximately 36%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe Radeon HD 4770 should be quite a bit (approximately 173%) better at anti-aliasing than the GeForce GT 240 GDDR5 1GB, and will be capable of handling higher screen resolutions without slowing down too much. (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 (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
