GeForce RTX 3090 vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which uses a 7 nm design. AMD has clocked the core speed at 2150 MHz. The GDDR6 memory runs at a speed of 2250 MHz on this card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6750 XT		250 Watts
GeForce RTX 3090		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

In theory, the GeForce RTX 3090 should be 117% faster than the Radeon RX 6750 XT in general, due to its higher data rate. (explain)

GeForce RTX 3090		958668 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 516300 (117%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (approximately 33%) better at AF 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

If using high levels of AA is important to you, then the GeForce RTX 3090 is superior to the Radeon RX 6750 XT, but not by far. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
