Radeon RX 570 vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this particular model. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon RX 570		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 22%) faster with regards to AF than the Radeon RX 570. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 32608 (22%)

Pixel Rate

The Radeon RX 6600 is much (more or less 178%) better at full screen anti-aliasing than the Radeon RX 570, and should be capable of handling higher resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 66688 (178%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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