Radeon R9 M370X vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R9 M375X will be quite a bit (more or less 27%) better at texture filtering than the Radeon R9 M370X. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 8600 (27%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (approximately 27%) better at FSAA than the Radeon R9 M370X, and capable of handling higher resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 3440 (27%)

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 information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
