Compare any two graphics cards:
Radeon R9 270X vs Radeon RX 470
IntroThe Radeon R9 270X has a clock frequency of 1000 MHz and a GDDR5 memory speed of 1400 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.
Compare that to the Radeon RX 470, which features core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon RX 470 should perform just a bit faster than the Radeon R9 270X overall. (explain)
Texel RateThe Radeon RX 470 will be much (more or less 48%) better at anisotropic filtering than the Radeon R9 270X. (explain)
Pixel RateThe Radeon R9 270X is a bit (more or less 8%) faster with regards to anti-aliasing than the Radeon RX 470, and also should be able to handle higher 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the max fill rate.
