Compare any two graphics cards:
Radeon R7 360 vs Radeon RX 460
IntroThe Radeon R7 360 makes use of a 28 nm design. AMD has clocked the core speed at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1625 MHz on this particular card. It features 768 SPUs as well as 48 Texture Address Units and 16 ROPs.
Compare all that to the Radeon RX 460, which has a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 460 should in theory be just a bit better than the Radeon R7 360 overall. (explain)
Texel RateThe Radeon RX 460 will be quite a bit (more or less 21%) more effective at AF than the Radeon R7 360. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon RX 460 is a better choice, not by a very large margin though. (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 data (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few 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.
