Radeon RX 580 vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which features GPU core speed of 2150 MHz, and 12288 MB of GDDR6 memory set to run at 2250 MHz through a 192-bit bus. It also features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Memory Bandwidth

As far as performance goes, the Radeon RX 6750 XT should theoretically be much superior to the Radeon RX 580 in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 180224 (69%)

Texel Rate

The Radeon RX 6750 XT should be quite a bit (approximately 90%) more effective at texture filtering than the Radeon RX 580. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 162992 (90%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6750 XT is a better choice, by a large margin. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 97376 (242%)

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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 the graphics card can possibly write to its 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 speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
