Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 5750 512MB
IntroThe GeForce GT 240 GDDR5 features a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.
Compare those specifications to the Radeon HD 5750 512MB, which features a GPU core clock speed of 700 MHz, and 512 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5750 512MB, in theory, should perform quite a bit faster than the GeForce GT 240 GDDR5 in general. (explain)
Texel RateThe Radeon HD 5750 512MB is a lot (about 43%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 5750 512MB should be much (about 155%) faster with regards to full screen anti-aliasing than the GeForce GT 240 GDDR5, and also will be capable of handling higher screen 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: Bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
