GeForce RTX 3090 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 RAM runs at a speed of 2250 MHz on this specific model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Radeon RX 6750 XT		442368 MB/sec
	Difference: 516300 (117%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (about 33%) faster with regards to texture filtering than the Radeon RX 6750 XT. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 113560 (33%)

Pixel Rate

The GeForce RTX 3090 will be just a bit (more or less 14%) faster with regards to FSAA than the Radeon RX 6750 XT, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 18640 (14%)

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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 applied per second. This number is worked out by multiplying the total number of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
