Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 7750
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this model. It features 96 SPUs along with 32 TAUs and 8 ROPs.
Compare all that to the Radeon HD 7750, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 7750 is 32% faster than the GeForce GT 240 GDDR5 overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 7750 is much (about 45%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7750 is superior to the GeForce GT 240 GDDR5, by far. (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 over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on many 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.
