Radeon RX 470 vs Radeon RX 7900 XT

Intro

Compare all of that to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has set the core speed at 1500 MHz. The GDDR6 memory is set to run at a speed of 2500 MHz on this card. It features 5376 SPUs as well as 336 TAUs and 192 ROPs.

Texel Rate

The Radeon RX 7900 XT is a lot (more or less 325%) better at anisotropic filtering than the Radeon RX 470. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 385472 (325%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 7900 XT is superior to the Radeon RX 470, by a large margin. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 258368 (872%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out 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 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
