Radeon R9 380 4G vs Radeon R9 M365X
Intro
The Radeon R9 380 4G comes with a GPU core clock speed of 970 MHz, and the 4096 MB of GDDR5 memory runs at 1425 MHz through a 256-bit bus. It also features 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total 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 one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
