GeForce RTX 3080 12 GB vs GeForce RTX 3080 Ti

Intro

Compare those specifications to the GeForce RTX 3080 Ti, which comes with core speeds of 1365 MHz on the GPU, and 1188 MHz on the 12288 MB of GDDR6X RAM. It features 10240 SPUs along with 320 Texture Address Units and 112 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce RTX 3080 12 GB should be a small bit faster than the GeForce RTX 3080 Ti overall. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
GeForce RTX 3080 Ti		934297 MB/sec
	Difference: 1 (0%)

Texel Rate

The GeForce RTX 3080 Ti should be much (about 24%) more effective at AF than the GeForce RTX 3080 12 GB. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3080 12 GB		352800 Mtexels/sec
	Difference: 84000 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080 12 GB, but not by far. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3080 12 GB		141120 Mpixels/sec
	Difference: 11760 (8%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many 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.
