Compare any two graphics cards:
Geforce GTX 690 vs Radeon HD 7970
IntroThe Geforce GTX 690 has a clock frequency of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.
Compare those specs to the Radeon HD 7970, which comes with a core clock speed of 925 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 690 will be 46% faster than the Radeon HD 7970 in general, due to its greater data rate. (explain)
Texel RateThe Geforce GTX 690 will be a lot (approximately 98%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateThe Geforce GTX 690 should be a lot (about 98%) better at full screen anti-aliasing than the Radeon HD 7970, and able to handle higher resolutions more effectively. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card could possibly write to its local memory in a 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
