Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 6750 1GB
IntroThe GeForce GT 240 GDDR5 has a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.
Compare all that to the Radeon HD 6750 1GB, which comes with a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6750 1GB should be 18% quicker than the GeForce GT 240 GDDR5 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6750 1GB should be much (more or less 48%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 6750 1GB will be much (approximately 164%) more effective at full screen anti-aliasing than the GeForce GT 240 GDDR5, and also should be able to handle 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
