Radeon RX 470 4GB vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 memory works at a frequency of 2250 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 22272 (19%)

Pixel Rate

The Radeon RX 6500 XT will be quite a bit (more or less 138%) faster with regards to full screen anti-aliasing than the Radeon RX 470 4GB, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 40768 (138%)

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 (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
