Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon RX 470		120 Watts
	Difference: 13 Watts (12%)

Memory Bandwidth

In theory, the Radeon RX 470 should perform quite a bit faster than the Radeon RX 6500 XT in general. (explain)

Radeon RX 470		211200 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 63744 (43%)

Texel Rate

The Radeon RX 6500 XT will be just a bit (approximately 19%) more effective at texture filtering than the Radeon RX 470. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 22272 (19%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6500 XT is a better choice, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 40768 (138%)

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 data (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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