Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6970
IntroThe Geforce GTX 670 features a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 32 ROPs.
Compare those specs to the Radeon HD 6970, which features a clock frequency of 880 MHz and a GDDR5 memory frequency of 1375 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is made up of 1536 SPUs, 96 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 670 will be 9% faster than the Radeon HD 6970 overall, because of its greater data rate. (explain)
Texel RateThe Geforce GTX 670 is a lot (about 21%) more effective at texture filtering than the Radeon HD 6970. (explain)
Pixel RateThe Geforce GTX 670 is a bit (more or less 4%) faster with regards to AA than the Radeon HD 6970, and should be able to handle higher screen 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.
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 (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
