Compare any two graphics cards:
Radeon HD 6790 vs Radeon RX 460
IntroThe Radeon HD 6790 makes use of a 40 nm design. AMD has clocked the core speed at 840 MHz. The GDDR5 memory is set to run at a frequency of 1050 MHz on this model. It features 800 SPUs as well as 40 Texture Address Units and 16 ROPs.
Compare those specs to the Radeon RX 460, which makes use of a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this model. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6790 should be 20% faster than the Radeon RX 460 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 460 will be much (about 82%) faster with regards to AF than the Radeon HD 6790. (explain)
Pixel RateThe Radeon RX 460 is quite a bit (approximately 30%) better at AA than the Radeon HD 6790, and also capable of handling 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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
