Radeon RX 5700 XT vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which uses a 7 nm design. AMD has set the core frequency at 2150 MHz. The GDDR6 RAM runs at a speed of 2250 MHz on this card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT will be 4% faster than the Radeon RX 6750 XT in general, due to its greater 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 is a lot (more or less 34%) more effective at AF 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 using a high resolution is important to you, then the Radeon RX 6750 XT is superior to the Radeon RX 5700 XT, and very much so. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied in one second. This is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant 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 maximum fill rate.
