GeForce RTX 3070 vs GeForce RTX 3080 Ti

Intro

Compare those specs to the GeForce RTX 3080 Ti, which makes use of a 8 nm design. nVidia has clocked the core frequency at 1365 MHz. The GDDR6X memory runs at a speed of 1188 MHz on this card. It features 10240 SPUs as well as 320 Texture Address Units and 112 Rasterization Operator Units.

GeForce RTX 3070		220 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 130 Watts (59%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be a little bit faster than the GeForce RTX 3070 in general. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 934297 (-100%)

Texel Rate

The GeForce RTX 3080 Ti will be quite a bit (more or less 58%) better at anisotropic filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 160800 (58%)

Pixel Rate

The GeForce RTX 3080 Ti will be a small bit (about 6%) faster with regards to full screen anti-aliasing than the GeForce RTX 3070, and capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 8880 (6%)

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 max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
