Radeon RX 580 vs Radeon RX 7900 XTX

Intro

Compare all of that to the Radeon RX 7900 XTX, which comes with core clock speeds of 1855 MHz on the GPU, and 2500 MHz on the 24576 MB of GDDR6 memory. It features 6144 SPUs as well as 384 TAUs and 192 Rasterization Operator Units.

Radeon RX 580		262144 MB/sec
	Difference: 720896 (275%)

Texel Rate

The Radeon RX 7900 XTX should be quite a bit (more or less 294%) better at texture filtering than the Radeon RX 580. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 531312 (294%)

Pixel Rate

The Radeon RX 7900 XTX is quite a bit (approximately 785%) more effective at AA than the Radeon RX 580, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 315936 (785%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 in a second.

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