Radeon RX 480 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which has core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 6600 XT should be much (approximately 56%) better at anisotropic filtering than the Radeon RX 480. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 90624 (56%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6600 XT is the winner, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 90112 (251%)

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 (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
