GeForce RTX 3080 12 GB vs GeForce RTX 3080 Ti

Intro

Compare all of that to the GeForce RTX 3080 Ti, which features 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 TAUs and 112 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 3080 12 GB should theoretically perform a bit faster than the GeForce RTX 3080 Ti in general. (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 quite a bit (more or less 24%) better at anisotropic filtering 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 a high screen resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080 12 GB, though 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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
