Radeon RX 470 4GB vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 470 4GB		211200 MB/sec
	Difference: 247552 (117%)

Texel Rate

The Radeon RX 5700 XT should be a lot (approximately 117%) faster with regards to anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 138272 (117%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5700 XT is the winner, and very much so. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 73088 (247%)

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 data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
