Radeon RX 480 4GB vs Radeon RX 6600

Intro

Compare all 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 along with 112 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 480 4GB		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 6600 should be just a bit (more or less 13%) better at AF than the Radeon RX 480 4GB. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 20832 (13%)

Pixel Rate

The Radeon RX 6600 will be much (approximately 190%) better at full screen anti-aliasing than the Radeon RX 480 4GB, and able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 480 4GB		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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
