Radeon RX 6600 XT vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which has a clock speed of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6750 XT is 69% faster than the Radeon RX 6600 XT in general, due to its higher data rate. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 180224 (69%)

Texel Rate

The Radeon RX 6750 XT should be a lot (about 37%) faster with regards to AF than the Radeon RX 6600 XT. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 92096 (37%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6750 XT is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 11648 (9%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
