Radeon RX 6750 XT vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this card. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

Radeon RX 6750 XT		442368 MB/sec
	Difference: 81920 (19%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 70%) faster with regards to anisotropic filtering than the Radeon RX 6750 XT. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 240000 (70%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the Radeon RX 6750 XT, by a large margin. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 96000 (70%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 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 are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
