Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti comes with a GPU core clock speed of 875 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1750 MHz through a 384-bit bus. It also features 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare all of that to the Radeon R9 290X, which comes with clock speeds of 800 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2816 SPUs as well as 176 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 780 Ti, in theory, should perform a bit faster than the Radeon R9 290X overall. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (more or less 49%) better at texture filtering than the Radeon R9 290X. (explain)
Pixel RateThe Radeon R9 290X should be much (about 22%) better at full screen anti-aliasing than the GeForce GTX 780 Ti, and will be able to handle higher screen 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.
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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 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 reach the max fill rate.
