Radeon RX 460 vs Radeon RX 460 2GB
Intro
The Radeon RX 460 uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.Compare all of that to the Radeon RX 460 2GB, which comes with GPU core speed of 1090 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should perform equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel fill rate, so theoretically they should perform equally good at at FSAA, and be capable of handling the same screen resolutions. (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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
