Compare any two graphics cards:
GeForce GTX 590 vs Radeon HD 5970
IntroThe GeForce GTX 590 features a GPU core clock speed of 607 MHz, and the 1536 MB of GDDR5 memory is set to run at 855 MHz through a 384-bit bus. It also features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.
Compare those specifications to the Radeon HD 5970, which makes use of a 40 nm design. ATi has clocked the core frequency at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 1600 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 590 should be 28% faster than the Radeon HD 5970 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 5970 should be quite a bit (approximately 199%) better at anisotropic filtering than the GeForce GTX 590. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 590, 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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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 (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, 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.
