Compare any two graphics cards:
GeForce GTX 980 Ti vs Radeon R9 390 8G
IntroThe GeForce GTX 980 Ti has a GPU core clock speed of 1000 MHz, and the 6144 MB of GDDR5 memory is set to run at 1750 MHz through a 384-bit bus. It also is comprised of 2816 Stream Processors, 176 Texture Address Units, and 96 Raster Operation Units.
Compare those specs to the Radeon R9 390 8G, which has clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Theoretically, the Radeon R9 390 8G should be a small bit faster than the GeForce GTX 980 Ti in general. (explain)
Texel RateThe GeForce GTX 980 Ti will be a small bit (approximately 10%) more effective at anisotropic filtering than the Radeon R9 390 8G. (explain)
Pixel RateThe GeForce GTX 980 Ti is quite a bit (more or less 50%) better at full screen anti-aliasing than the Radeon R9 390 8G, and able to handle higher resolutions better. (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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better 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 maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
