Radeon RX 470 4GB vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

	Difference: 50944 (24%)

Texel Rate

The Radeon RX 6600 XT will be quite a bit (about 113%) better at AF than the Radeon RX 470 4GB. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 133376 (113%)

Pixel Rate

If using high levels of AA 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 470 4GB		29632 Mpixels/sec
	Difference: 96320 (325%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
