GeForce 920M vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 550 should be quite a bit faster than the GeForce 920M in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The Radeon RX 550 will be a little bit (approximately 15%) better at texture filtering than the GeForce 920M. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 4672 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 550 is the winner, by far. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 9968 (131%)

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 max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
