Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 features a clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also makes use of a 320-bit bus, and makes use of a 40 nm design. It is made up of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.
Compare those specifications to the Radeon HD 6970, which comes with a clock frequency of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6970 should be a lot faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 will be a lot (more or less 149%) more effective at texture filtering than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 6970 is just a bit (more or less 16%) better at full screen anti-aliasing than the GeForce GTX 470, and should be capable of handling higher resolutions while still performing well. (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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
