Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM is set to run at a frequency of 837 MHz on this particular model. It features 448 SPUs along with 56 TAUs and 40 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6970, which has a clock speed of 880 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6970, in theory, should perform quite a bit faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 is much (about 149%) more effective at AF than the GeForce GTX 470. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6970 is superior to the GeForce GTX 470, though not 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.
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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher 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 write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
