GeForce 820M vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which has a clock frequency of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 820M		15 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 115 Watts (767%)

Memory Bandwidth

The Radeon RX 5500 XT should theoretically perform a lot faster than the GeForce 820M in general. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce 820M		16000 MB/sec
	Difference: 213376 (1334%)

Texel Rate

The Radeon RX 5500 XT is quite a bit (about 1213%) faster with regards to anisotropic filtering than the GeForce 820M. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce 820M		11504 Mtexels/sec
	Difference: 139592 (1213%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is superior to the GeForce 820M, and very much so. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce 820M		2876 Mpixels/sec
	Difference: 52068 (1810%)

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 largest amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
