Radeon R9 M375X vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 460 should be a lot faster 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 should be much (about 50%) faster with regards to 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

The Radeon RX 460 should be a bit (more or less 7%) more effective at full screen anti-aliasing than the Radeon R9 M375X, and will be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
