VS

Radeon RX 480 vs Radeon RX 480 4GB

Intro

The Radeon RX 480 makes use of a 14 nm design. AMD has clocked the core speed at 1120 MHz. The GDDR5 RAM works at a frequency of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 480 should theoretically be a little bit superior to 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 anisotropic filtering. (explain)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should perform equally good at at 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
