Radeon RX 480 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which has GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM running at 2250 MHz through a 64-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon RX 480		150 Watts
	Difference: 43 Watts (40%)

Memory Bandwidth

In theory, the Radeon RX 480 should be 78% faster than the Radeon RX 6500 XT overall, because of its higher data rate. (explain)

Radeon RX 480		262144 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 114688 (78%)

Texel Rate

The Radeon RX 480 should be a small bit (more or less 15%) better at texture filtering than the Radeon RX 6500 XT. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 20480 (15%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6500 XT is the winner, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 34560 (96%)

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 across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
