GeForce RTX 4070 Ti vs Geforce GTX 1080 Ti

Intro

Compare all of that to the Geforce GTX 1080 Ti, which comes with a clock speed of 1480 MHz and a GDDR5X memory speed of 1376 MHz. It also makes use of a 352-bit memory bus, and makes use of a 16 nm design. It features 3584 SPUs, 224 Texture Address Units, and 88 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti should perform a small bit faster than the Geforce GTX 1080 Ti in general. (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 will be quite a bit (more or less 67%) more effective at anisotropic filtering 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 using lots of anti-aliasing is important to you, then the GeForce RTX 4070 Ti is superior to the Geforce GTX 1080 Ti, and very much so. (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 moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
