Radeon RX 470 vs Radeon RX 470 4GB


Intro

The Radeon RX 470 features a GPU core clock speed of 926 MHz, and the 8192 MB of GDDR5 memory is set to run at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Compare those specifications to the Radeon RX 470 4GB, which features a core clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

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 the exact 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 be equally good at at anti-aliasing, and be able to handle 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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
