Radeon R9 M375 vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which uses a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 550 will be 226% faster than the Radeon R9 M375 overall, because of its higher data rate. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 79488 (226%)

Texel Rate

The Radeon R9 M375 should be just a bit (more or less 15%) faster with regards to AF than the Radeon RX 550. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 5400 (15%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is superior to the Radeon R9 M375, but not by far. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M375		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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of 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 worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
