GeForce RTX 2080 SUPER vs GeForce RTX 3090

Intro

Compare that to the GeForce RTX 3090, which uses a 8 nm design. nVidia has clocked the core speed at 1395 MHz. The GDDR6X RAM runs at a speed of 1219 MHz on this specific card. It features 10496 SPUs along with 328 Texture Address Units and 112 ROPs.

GeForce RTX 2080 SUPER		250 Watts
GeForce RTX 3090		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3090 is 89% quicker than the GeForce RTX 2080 SUPER overall, because of its higher data rate. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 450764 (89%)

Texel Rate

The GeForce RTX 3090 is a lot (approximately 44%) faster with regards to AF than the GeForce RTX 2080 SUPER. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 140760 (44%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3090 is a better choice, by far. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 50640 (48%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
