Radeon RX 470 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

Radeon RX 470		118528 Mtexels/sec
	Difference: 63584 (54%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 is superior to the Radeon RX 470, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 74432 (251%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
