Radeon RX 480 4GB vs Radeon RX 5700

Intro

The Radeon RX 480 4GB features a core clock frequency of 1120 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and uses a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

Compare all of that to the Radeon RX 5700, which comes with core speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
