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 memory 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 specs to the Radeon R9 290X, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. 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, the GeForce GTX 780 Ti should be just a bit faster than the Radeon R9 290X in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (approximately 49%) faster with regards to AF than the Radeon R9 290X. (explain)
Pixel RateThe Radeon R9 290X is much (approximately 22%) better at FSAA than the GeForce GTX 780 Ti, and also should be capable of handling higher screen 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
