GeForce RTX 3080 Ti vs GeForce RTX 3090

Intro

The GeForce RTX 3080 Ti comes with a GPU core speed of 1365 MHz, and the 12288 MB of GDDR6X memory runs at 1188 MHz through a 384-bit bus. It also is comprised of 10240 SPUs, 320 TAUs, and 112 Raster Operation Units.

Compare that to the GeForce RTX 3090, which features a clock speed of 1395 MHz and a GDDR6X memory speed of 1219 MHz. It also features a 384-bit memory bus, and uses a 8 nm design. It features 10496 SPUs, 328 Texture Address Units, and 112 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce RTX 3090 should perform a little 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 is a small bit (more or less 5%) better at AF 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 running with a high resolution is important to you, then the GeForce RTX 3090 is a better choice, not by a very large margin though. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
