Radeon R9 M375X vs Radeon RX Vega 56

Intro

The Radeon R9 M375X features a GPU core clock speed of 1015 MHz, and the 4096 MB of GDDR5 RAM runs at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon RX Vega 56, which has core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs as well as 224 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
