Radeon RX 470 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which features core clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs along with 112 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
Radeon RX 6600		132 Watts
	Difference: 12 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 should be 9% quicker than the Radeon RX 470 in general, because of its higher data rate. (explain)

Radeon RX 6600		229376 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 6600 should be much (more or less 54%) better at texture filtering than the Radeon RX 470. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 63584 (54%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 is superior to the Radeon RX 470, and very much so. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 74432 (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
