Radeon RX 470 4GB vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which comes with a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Texel Rate

The Radeon RX 5600 is a lot (about 48%) faster with regards to anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 57472 (48%)

Pixel Rate

The Radeon RX 5600 should be a lot (more or less 197%) more effective at anti-aliasing than the Radeon RX 470 4GB, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 58368 (197%)

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 past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
