Radeon R9 M365X vs Radeon R9 M375X

Intro

The Radeon R9 M365X features a GPU core clock speed of 925 MHz, and the 4096 MB of GDDR5 RAM runs at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M375X, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The GDDR5 memory works at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 M375X should be a bit (about 10%) better at texture filtering than the Radeon R9 M365X. (explain)

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

Pixel Rate

The Radeon R9 M375X is a small bit (more or less 10%) more effective at full screen anti-aliasing than the Radeon R9 M365X, and will be able to handle higher screen resolutions more effectively. (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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
