Radeon R9 M375 vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which makes use of 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.

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

Texel Rate

The Radeon R9 M375 is a small bit (approximately 15%) faster with regards to anisotropic filtering than the Radeon RX 550. (explain)

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

Pixel Rate

The Radeon RX 550 will be a small bit (approximately 8%) faster with regards to anti-aliasing than the Radeon R9 M375, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 applied per 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 better 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 bandwidth is, the lower the potential to reach the max fill rate.
