Radeon R9 380 4G vs Radeon RX 470 4GB

Intro

The Radeon R9 380 4G comes with a GPU core clock speed of 970 MHz, and the 4096 MB of GDDR5 RAM runs at 1425 MHz through a 256-bit bus. It also is comprised of 1792 SPUs, 112 TAUs, and 32 ROPs.

Compare those specs to the Radeon RX 470 4GB, which features a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
