Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 875 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.
Compare those specifications to the Radeon R9 290X, which has core 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 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 780 Ti will be 5% faster than the Radeon R9 290X overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (about 49%) more effective at AF than the Radeon R9 290X. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 290X is a better choice, and very much so. (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 (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once 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 anti-aliasing, 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 number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
