GeForce 920M vs Radeon RX 550

Intro

The GeForce 920M features a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 TAUs, and 8 ROPs.

Compare those specifications to the Radeon RX 550, which has clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

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

Pixel Rate

The Radeon RX 550 will be much (more or less 131%) more effective at AA than the GeForce 920M, and capable of handling higher resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
