GeForce RTX 3080 Ti vs GeForce RTX 3090

Intro

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

Compare all of that to the GeForce RTX 3090, which features GPU core speed of 1395 MHz, and 24576 MB of GDDR6X memory running at 1219 MHz through a 384-bit bus. It also features 10496 Stream Processors, 328 TAUs, and 112 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 3090, in theory, should be a small 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%) more effective at anisotropic 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 a high screen resolution is important to you, then the GeForce RTX 3090 is superior to the GeForce RTX 3080 Ti, but not by far. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of 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 the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
