Radeon RX 470 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this model. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Texel Rate

The Radeon RX 6600 XT will be much (about 113%) more effective at anisotropic filtering than the Radeon RX 470. (explain)

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

Pixel Rate

The Radeon RX 6600 XT is much (about 325%) more effective at AA than the Radeon RX 470, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 470		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 transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
