GeForce RTX 3080 vs GeForce RTX 3080 Ti

Intro

Compare that to the GeForce RTX 3080 Ti, which makes use of a 8 nm design. nVidia has clocked the core frequency at 1365 MHz. The GDDR6X RAM is set to run at a speed of 1188 MHz on this model. It features 10240 SPUs along with 320 Texture Address Units and 112 Rasterization Operator Units.

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080, not by a very large margin though. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the 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 clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
