Radeon R9 M395X vs Radeon RX 6500 XT

Intro

The Radeon R9 M395X features a GPU clock speed of 723 MHz, and the 4096 MB of GDDR5 memory is set to run at 1250 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Compare those specifications to the Radeon RX 6500 XT, which features clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
