GeForce RTX 3070 Ti vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which features a GPU core clock speed of 1440 MHz, and 10240 MB of GDDR6X RAM set to run at 1188 MHz through a 320-bit bus. It also is made up of 8704 Stream Processors, 272 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 Ti		290 Watts
GeForce RTX 3080		320 Watts
	Difference: 30 Watts (10%)

Memory Bandwidth

The GeForce RTX 3080, in theory, should perform quite a bit faster than the GeForce RTX 3070 Ti in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 155648 (25%)

Texel Rate

The GeForce RTX 3080 should be a lot (approximately 30%) more effective at texture filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 89280 (30%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is the winner, not by a very large margin though. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 12960 (9%)

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 (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If 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 can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
