Radeon RX 5700 XT vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2150 MHz. The GDDR6 memory is set to run at a speed of 2250 MHz on this specific card. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

	Difference: 25 Watts (11%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT is 4% faster than the Radeon RX 6750 XT in general, because of its higher data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 16384 (4%)

Texel Rate

The Radeon RX 6750 XT will be a lot (about 34%) more effective at anisotropic filtering than the Radeon RX 5700 XT. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 87200 (34%)

Pixel Rate

If running with a high resolution 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 5700 XT		102720 Mpixels/sec
	Difference: 34880 (34%)

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 data (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
