GeForce RTX 3070 Ti vs GeForce RTX 3080 Ti

Intro

Compare those specs to the GeForce RTX 3080 Ti, which comes with a GPU core clock speed of 1365 MHz, and 12288 MB of GDDR6X memory set to run at 1188 MHz through a 384-bit bus. It also is made up of 10240 Stream Processors, 320 TAUs, and 112 Raster Operation Units.

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 is 50% quicker than the GeForce RTX 3070 Ti in general, because of its greater data rate. (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 should be a lot (more or less 44%) more effective at 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 running with a high screen resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3070 Ti, not by a very large margin though. (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 MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
