Radeon RX 480 vs Radeon RX 480 4GB

Intro

The Radeon RX 480 comes with a GPU core clock speed of 1120 MHz, and the 8192 MB of GDDR5 memory runs at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Compare that to the Radeon RX 480 4GB, which comes with core speeds of 1120 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2304 SPUs along with 144 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 480 should be a little bit faster than the Radeon RX 480 4GB in general. (explain)

Radeon RX 480 262144 MB/sec
Radeon RX 480 4GB 229376 MB/sec
Difference: 32768 (14%)

Texel Rate

Both cards have the exact same texel rate, so theoretically they should perform equally good at at AF. (explain)

Pixel Rate

Both cards have the exact same pixel fill rate, so in theory 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
