Radeon RX 570 vs Radeon RX 7900 XT

Intro

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

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

Texel Rate

The Radeon RX 7900 XT is quite a bit (more or less 237%) faster with regards to AF than the Radeon RX 570. (explain)

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

Pixel Rate

The Radeon RX 7900 XT is a lot (about 671%) faster with regards to full screen anti-aliasing than the Radeon RX 570, and also will be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. 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 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
