Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 5750 512MB
IntroThe GeForce GT 240 GDDR5 features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is comprised of 96 SPUs, 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 set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 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 in theory be a lot superior to the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe Radeon HD 5750 512MB will be quite a bit (about 43%) more effective at AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 5750 512MB is a lot (approximately 155%) better at AA than the GeForce GT 240 GDDR5, and able to handle higher 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 max amount of data (measured in MB 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 RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 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.
