Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 7750
IntroThe GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this model. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.
Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. ATi has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7750 should be 32% quicker than the GeForce GT 240 GDDR5 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 7750 should be quite a bit (more or less 45%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 7750 should be a lot (about 191%) faster with regards to full screen anti-aliasing than the GeForce GT 240 GDDR5, and capable of handling higher screen resolutions without losing too much performance. (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 information (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
