GeForce RTX 3080 Ti vs GeForce RTX 3090

Intro

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 3090 should theoretically be a bit faster than the GeForce RTX 3080 Ti overall. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce RTX 3080 Ti		934297 MB/sec
	Difference: 24371 (3%)

Texel Rate

The GeForce RTX 3090 should be just a bit (approximately 5%) better at texture filtering than the GeForce RTX 3080 Ti. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce RTX 3080 Ti		436800 Mtexels/sec
	Difference: 20760 (5%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3090 is superior to the GeForce RTX 3080 Ti, though only just barely. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce RTX 3080 Ti		152880 Mpixels/sec
	Difference: 3360 (2%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock 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 better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
