GeForce 930M vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

GeForce 930M		22272 Mtexels/sec
	Difference: 12928 (58%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is the winner, by a large margin. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 10176 (137%)

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 max amount of information (measured 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 interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
