Radeon R9 M375X vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 550 should be much faster than the Radeon R9 M375X in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon R9 M375X will be just a bit (about 15%) better at anisotropic filtering than the Radeon RX 550. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 5400 (15%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 550 is superior to the Radeon R9 M375X, not by a very large margin though. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 1360 (8%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
