GeForce RTX 3070 Ti vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3070 Ti comes with a GPU clock speed of 1575 MHz, and the 8192 MB of GDDR6X memory is set to run at 1188 MHz through a 256-bit bus. It also features 6144 Stream Processors, 192 Texture Address Units, and 96 ROPs.

Compare those specs to the GeForce RTX 3080 Ti, which features a GPU core clock speed of 1365 MHz, and 12288 MB of GDDR6X RAM running at 1188 MHz through a 384-bit bus. It also features 10240 Stream Processors, 320 TAUs, and 112 ROPs.

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 a lot 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 will be a lot (about 44%) better 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

The GeForce RTX 3080 Ti is a bit (more or less 1%) more effective at full screen anti-aliasing than the GeForce RTX 3070 Ti, and will be capable of handling higher resolutions without slowing down too much. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
