Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 5750 512MB
IntroThe GeForce GT 240 GDDR5 has a clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.
Compare those specs to the Radeon HD 5750 512MB, which features GPU clock speed of 700 MHz, and 512 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 5750 512MB should theoretically be much better than the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe Radeon HD 5750 512MB will be much (approximately 43%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 5750 512MB is a better choice, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
