Radeon RX 5700 vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which uses a 7 nm design. AMD has clocked the core speed at 2150 MHz. The GDDR6 RAM is set to run at a frequency of 2250 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Radeon RX 5700		180 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 should perform a little bit faster than the Radeon RX 6750 XT in general. (explain)

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

Texel Rate

The Radeon RX 6750 XT should be quite a bit (more or less 63%) faster with regards to AF than the Radeon RX 5700. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 133040 (63%)

Pixel Rate

The Radeon RX 6750 XT should be much (more or less 47%) more effective at full screen anti-aliasing than the Radeon RX 5700, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 43840 (47%)

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 (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
