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 clocked the core frequency at 607 MHz. The GDDR5 RAM runs at a speed of 837 MHz on this specific model. It features 448 SPUs as well as 56 TAUs and 40 Rasterization Operator Units.
Compare all of that to the Radeon HD 6970, which has a GPU core clock speed of 880 MHz, and 2048 MB of GDDR5 memory set to run at 1375 MHz through a 256-bit bus. It also features 1536 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

When combining all game benchmark scores on this page together, the Radeon HD 6970 wins overall, by 41 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6970 should in theory perform a lot faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 should 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 (about 16%) faster with regards to anti-aliasing than the GeForce GTX 470, and also capable of handling higher 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.
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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of 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 applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
