Compare any two graphics cards:
Radeon HD 6850 vs Radeon RX 460
IntroThe Radeon HD 6850 uses a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 960 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.
Compare those specifications to the Radeon RX 460, which comes with core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6850 is 14% quicker than the Radeon RX 460 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 460 should be much (more or less 64%) more effective at anisotropic filtering than the Radeon HD 6850. (explain)
Pixel RateThe Radeon HD 6850 should be much (about 42%) better at FSAA than the Radeon RX 460, and should be able to handle higher resolutions more effectively. (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 moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
