Radeon RX 470 4GB vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular model. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Radeon RX 470 4GB		211200 MB/sec
	Difference: 313088 (148%)

Texel Rate

The Radeon RX 6900 XT will be a lot (about 393%) better at anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 465472 (393%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 203968 (688%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends 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 max fill rate.
