Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti has a clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 TAUs, and 48 ROPs.
Compare that to the Radeon R9 290X, which has a core clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 512-bit bus, and uses a 28 nm design. It is comprised of 2816 SPUs, 176 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 780 Ti should in theory be a bit superior to the Radeon R9 290X in general. (explain)
Texel RateThe GeForce GTX 780 Ti is quite a bit (approximately 49%) better at anisotropic filtering than the Radeon R9 290X. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 290X is a better choice, 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 megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
