Radeon R9 M375X vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which comes with core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 470 4GB should in theory be a lot superior to the Radeon R9 M375X overall. (explain)

Radeon RX 470 4GB		211200 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 139200 (193%)

Texel Rate

The Radeon RX 470 4GB will be much (more or less 192%) more effective at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 77928 (192%)

Pixel Rate

The Radeon RX 470 4GB is quite a bit (approximately 82%) more effective at anti-aliasing than the Radeon R9 M375X, and should be able to handle higher resolutions better. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
Radeon R9 M375X		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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core 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 video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
