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 speed at 875 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.
Compare those specifications to the Radeon R9 290X, which has a clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 512-bit bus, and makes use of a 28 nm design. It is comprised of 2816 SPUs, 176 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 780 Ti should perform just a bit faster than the Radeon R9 290X in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (approximately 49%) better at anisotropic filtering than the Radeon R9 290X. (explain)
Pixel RateThe Radeon R9 290X is quite a bit (more or less 22%) more effective at full screen anti-aliasing than the GeForce GTX 780 Ti, and 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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
