Compare any two graphics cards:
GeForce GTX 970 vs Radeon R9 280X
IntroThe GeForce GTX 970 comes with a clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It features 1664 SPUs, 104 Texture Address Units, and 64 ROPs.
Compare that to the Radeon R9 280X, which comes with a clock speed of 850 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

As far as performance goes, the Radeon R9 280X should theoretically be much superior to the GeForce GTX 970 overall. (explain)
Texel RateThe GeForce GTX 970 is a little bit (more or less 0%) better at AF than the Radeon R9 280X. (explain)
Pixel RateThe GeForce GTX 970 should be quite a bit (more or less 147%) faster with regards to anti-aliasing than the Radeon R9 280X, and also able to handle higher screen resolutions without losing too much performance. (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 MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, 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 high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
