Compare any two graphics cards:
GeForce GTX 465 vs Radeon RX 460
IntroThe GeForce GTX 465 has a core clock frequency of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.
Compare that to the Radeon RX 460, which features a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 460 should theoretically be a little bit better than the GeForce GTX 465 in general. (explain)
Texel RateThe Radeon RX 460 should be a lot (about 129%) faster with regards to texture filtering than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 is a bit (about 11%) better at FSAA than the Radeon RX 460, and capable of handling higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
