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 clocked the core frequency at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this card. It features 96 SPUs along with 32 TAUs and 8 ROPs.
Compare all that to the Radeon HD 7750, which features core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7750 should theoretically be a lot faster than the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe Radeon HD 7750 will be much (about 45%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 7750 is a lot (more or less 191%) faster with regards to anti-aliasing than the GeForce GT 240 GDDR5, and also will be 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, 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 figure is worked out by multiplying the total texture units by the core clock 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its 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 core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
