Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 7970
IntroThe Geforce GTX 670 comes with a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory runs at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 32 ROPs.
Compare those specifications to the Radeon HD 7970, which has a clock speed of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 7970 should be a lot faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Radeon HD 7970 will be a little bit (approximately 16%) more effective at AF than the Geforce GTX 670. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7970 is superior to the Geforce GTX 670, but it probably won't make a huge difference. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of 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 high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
