Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 5750 1GB
IntroThe Geforce GTX 680 comes with a core clock speed of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 5750 1GB, which features a GPU core clock speed of 700 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 680 should be 161% quicker than the Radeon HD 5750 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe Geforce GTX 680 is much (more or less 411%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Geforce GTX 680 is superior to the Radeon HD 5750 1GB, by a large margin. (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 information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
