GeForce RTX 3070 Ti vs GeForce RTX 3080 Ti

Intro

Compare those specifications to the GeForce RTX 3080 Ti, which makes use of a 8 nm design. nVidia has clocked the core speed at 1365 MHz. The GDDR6X RAM works at a frequency of 1188 MHz on this specific model. It features 10240 SPUs as well as 320 TAUs and 112 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 Ti		290 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 60 Watts (21%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should perform quite a bit faster than the GeForce RTX 3070 Ti overall. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 311398 (50%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (more or less 44%) faster with regards to anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 134400 (44%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 Ti is the winner, though only just barely. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 1680 (1%)

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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
