Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti comes with a GPU clock speed of 875 MHz, and the 3072 MB of GDDR5 memory runs at 1750 MHz through a 384-bit bus. It also is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.
Compare those specifications to the Radeon R9 290X, which features GPU clock speed of 800 MHz, and 4096 MB of GDDR5 memory running at 1250 MHz through a 512-bit bus. It also is comprised of 2816 Stream Processors, 176 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 780 Ti should be just a bit faster than the Radeon R9 290X overall. (explain)
Texel RateThe GeForce GTX 780 Ti will be much (about 49%) more effective at texture filtering than the Radeon R9 290X. (explain)
Pixel RateThe Radeon R9 290X should be a lot (more or less 22%) faster with regards to FSAA than the GeForce GTX 780 Ti, and should be able to handle 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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 that the graphics card can possibly record to its local memory in one 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
