Radeon RX 470 4GB 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 RAM works at a frequency of 2000 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT is 24% faster than the Radeon RX 470 4GB in general, because of its higher bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 50944 (24%)

Texel Rate

The Radeon RX 6600 XT will be quite a bit (approximately 113%) more effective 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 running with a high resolution is important to you, then the Radeon RX 6600 XT is superior to the Radeon RX 470 4GB, and very much so. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 ability to get to the maximum fill rate.
