Radeon R9 380 2G vs Radeon RX 6700 XT

Intro

The Radeon R9 380 2G uses a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 RAM runs at a speed of 1425 MHz on this card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon RX 6700 XT, which comes with GPU core speed of 2321 MHz, and (Unknown) MB of GDDR6 RAM set to run at 2000 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 of the card by the core speed of the chip. The higher the texel rate, the better the video 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 its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
