GeForce 920M vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features a GPU core clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

GeForce 920M		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The Radeon RX 550 should be just a bit (about 15%) better at AF than the GeForce 920M. (explain)

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

Pixel Rate

The Radeon RX 550 is a lot (about 131%) faster with regards to AA than the GeForce 920M, and also should be capable of handling higher resolutions while still performing well. (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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
