Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 comes with a core clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.
Compare those specs to the Radeon HD 6970, which makes use of a 40 nm design. AMD has clocked the core frequency at 880 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this particular card. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6970 should in theory be quite a bit better than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 is quite a bit (approximately 149%) more effective at AF than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 6970 will be a little bit (about 16%) more effective at anti-aliasing than the GeForce GTX 470, and 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
