Radeon R9 M375X vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which comes with a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 550 should perform quite a bit faster than the Radeon R9 M375X overall. (explain)

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

Texel Rate

The Radeon R9 M375X will be a little bit (approximately 15%) faster with regards to texture filtering 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 will be a little 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 memory bandwidth is, the lower the potential to reach the maximum fill rate.
