Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 5750 512MB
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.
Compare all that to the Radeon HD 5750 512MB, which makes use of a 40 nm design. ATi has clocked the core speed at 700 MHz. The GDDR5 memory works at a frequency of 1150 MHz on this particular model. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 5750 512MB should be 35% faster than the GeForce GT 240 GDDR5 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 5750 512MB is a lot (approximately 43%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 5750 512MB will be much (approximately 155%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and capable of handling higher resolutions more effectively. (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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 get to the max fill rate.
