Radeon R9 M375X vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

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

Pixel Rate

The Radeon RX 550 is a bit (approximately 8%) faster with regards to FSAA than the Radeon R9 M375X, and should be able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total number of 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 amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
