Radeon RX 470 vs Radeon RX 480 4GB


Intro

The Radeon RX 470 uses a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM works at a speed of 1650 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 480 4GB, which features GPU core speed of 1120 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
