Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 6750 1GB
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.
Compare those specs to the Radeon HD 6750 1GB, which uses a 40 nm design. ATi has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this card. It features 720 SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6750 1GB is 18% faster than the GeForce GT 240 GDDR5 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6750 1GB is much (approximately 48%) better at AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6750 1GB is the winner, by a large margin. (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 largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card 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 graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
