Radeon R9 M365X vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R9 M375X will be a bit (more or less 10%) faster with regards to 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 running with a high screen resolution is important to you, then the Radeon R9 M375X is superior to the Radeon R9 M365X, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
