Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6970
IntroThe Geforce GTX 670 comes with a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 6970, which makes use of a 40 nm design. AMD has set the core speed at 880 MHz. The GDDR5 RAM runs at a speed of 1375 MHz on this model. It features 1536 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 670 should be a little bit faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Geforce GTX 670 will be a lot (about 21%) faster with regards to anisotropic filtering than the Radeon HD 6970. (explain)
Pixel RateThe Geforce GTX 670 should be a small bit (approximately 4%) more effective at FSAA than the Radeon HD 6970, and also should be able to handle higher resolutions better. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
