Radeon RX 480 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which features clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 480		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 should perform just a bit faster than the Radeon RX 6600 overall. (explain)

Radeon RX 480		262144 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 should be a bit (approximately 13%) more effective at texture filtering than the Radeon RX 480. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 20832 (13%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6600 is a better choice, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 68224 (190%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
