Radeon R9 380 4G vs Radeon RX 6700 XT
Intro
The Radeon R9 380 4G features a core clock frequency of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon RX 6700 XT, which features GPU clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory set to run at 2000 MHz through a 192-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed 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 better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
