GeForce RTX 3080 vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3080 features a core clock speed of 1440 MHz and a GDDR6X memory speed of 1188 MHz. It also makes use of a 320-bit bus, and uses a 8 nm design. It features 8704 SPUs, 272 Texture Address Units, and 96 ROPs.

Compare all of that to the GeForce RTX 3080 Ti, which comes with GPU clock speed of 1365 MHz, and 12288 MB of GDDR6X memory running at 1188 MHz through a 384-bit bus. It also is comprised of 10240 SPUs, 320 TAUs, and 112 ROPs.

GeForce RTX 3080 320 Watts
GeForce RTX 3080 Ti 350 Watts
Difference: 30 Watts (9%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be a small bit faster than the GeForce RTX 3080 overall. (explain)

GeForce RTX 3080 Ti 934297 MB/sec
GeForce RTX 3080 778547 MB/sec
Difference: 155750 (20%)

Texel Rate

The GeForce RTX 3080 Ti is a small bit (more or less 12%) better at AF than the GeForce RTX 3080. (explain)

GeForce RTX 3080 Ti 436800 Mtexels/sec
GeForce RTX 3080 391680 Mtexels/sec
Difference: 45120 (12%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080, though only just barely. (explain)

GeForce RTX 3080 Ti 152880 Mpixels/sec
GeForce RTX 3080 138240 Mpixels/sec
Difference: 14640 (11%)

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 max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
