GeForce GTX 850M vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which has GPU core speed of 1717 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

GeForce GTX 850M		32000 MB/sec
	Difference: 197376 (617%)

Texel Rate

The Radeon RX 5500 XT should be quite a bit (approximately 331%) faster with regards to texture filtering than the GeForce GTX 850M. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 850M		35040 Mtexels/sec
	Difference: 116056 (331%)

Pixel Rate

The Radeon RX 5500 XT is much (approximately 292%) better at AA than the GeForce GTX 850M, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 850M		14016 Mpixels/sec
	Difference: 40928 (292%)

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 information (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
