GeForce RTX 4070 Ti vs Geforce GTX 1080 Ti

Intro

Compare those specifications to the Geforce GTX 1080 Ti, which uses a 16 nm design. nVidia has set the core speed at 1480 MHz. The GDDR5X memory works at a speed of 1376 MHz on this card. It features 3584 SPUs along with 224 TAUs and 88 ROPs.

Geforce GTX 1080 Ti		250 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 35 Watts (14%)

Memory Bandwidth

In theory, the GeForce RTX 4070 Ti will be 4% quicker than the Geforce GTX 1080 Ti in general, due to its greater bandwidth. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 20480 (4%)

Texel Rate

The GeForce RTX 4070 Ti should be much (approximately 67%) better at AF than the Geforce GTX 1080 Ti. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 222880 (67%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 4070 Ti is a better choice, by far. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 54560 (42%)

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 information (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
