Radeon R9 M375 vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which features a core clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 470 is 500% quicker than the Radeon R9 M375 overall, because of its greater data rate. (explain)

Radeon RX 470		211200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 176000 (500%)

Texel Rate

The Radeon RX 470 will be much (about 192%) faster with regards to AF than the Radeon R9 M375. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 77928 (192%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 470 is a better choice, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 13392 (82%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
