Radeon R9 M375X vs Radeon RX 460

Intro

Compare that to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 460 should theoretically be a lot better than the Radeon R9 M375X overall. (explain)

Radeon RX 460		112000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 40000 (56%)

Texel Rate

The Radeon RX 460 will be quite a bit (approximately 50%) better at texture filtering than the Radeon R9 M375X. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 20440 (50%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, but not by far. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 1200 (7%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
