VS

Radeon RX 470 vs Radeon RX 470 4GB


Intro

The Radeon RX 470 features core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Compare that to the Radeon RX 470 4GB, which features GPU core speed of 926 MHz, and 4096 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

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

Pixel Rate

Both cards have the exact same pixel rate, so in theory they should perform equally good at at full screen 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
