Radeon R9 M365X vs Radeon R9 M375X

Intro

The Radeon R9 M365X features a GPU core speed of 925 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Compare that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon R9 M375X should be a small bit (approximately 10%) better at AF than the Radeon R9 M365X. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 3600 (10%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375X is a better choice, though not by far. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 1440 (10%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
