GeForce RTX 2080 vs GeForce RTX 3070 Ti

Intro

Compare all of that to the GeForce RTX 3070 Ti, which uses a 8 nm design. nVidia has set the core frequency at 1575 MHz. The GDDR6X RAM works at a speed of 1188 MHz on this particular card. It features 6144 SPUs as well as 192 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 75 Watts (35%)

Memory Bandwidth

Performance-wise, the GeForce RTX 3070 Ti should in theory be a lot superior to the GeForce RTX 2080 overall. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 164147 (36%)

Texel Rate

The GeForce RTX 3070 Ti is a small bit (approximately 8%) more effective at texture filtering than the GeForce RTX 2080. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 23640 (8%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is a better choice, and very much so. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 54240 (56%)

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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
