Radeon RX 570 vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which features a clock speed of 1500 MHz and a GDDR6 memory speed of 2500 MHz. It also features a 320-bit memory bus, and makes use of a 5 nm design. It is made up of 5376 SPUs, 336 Texture Address Units, and 192 Raster Operation Units.

Radeon RX 570		150 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 150 Watts (100%)

Memory Bandwidth

In theory, the Radeon RX 7900 XT should perform quite a bit faster than the Radeon RX 570 overall. (explain)

Radeon RX 7900 XT		819200 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 589824 (257%)

Texel Rate

The Radeon RX 7900 XT will be much (about 237%) more effective at anisotropic filtering than the Radeon RX 570. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 354496 (237%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 7900 XT is superior to the Radeon RX 570, and very much so. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 250624 (671%)

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 data (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus 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 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
