Radeon RX 470 vs Radeon RX 470 4GB

Intro

The Radeon RX 470 has a GPU core clock speed of 926 MHz, and the 8192 MB of GDDR5 RAM runs at 1650 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 RAM runs at a frequency of 1650 MHz on this specific model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

Both cards have the exact same texel rate, so in theory they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

Both cards have the exact same pixel rate, so theoretically they should perform equally good at at full screen anti-aliasing, and be capable of handling the same 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 information (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 this number, the better the graphics 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 maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
