GeForce GTX 1080 vs GeForce RTX 3060 Ti

Intro

Compare that to the GeForce RTX 3060 Ti, which has a clock speed of 1410 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 8 nm design. It is made up of 4864 SPUs, 152 TAUs, and 80 ROPs.

GeForce RTX 3060 Ti		214320 Mtexels/sec
	Difference: 42800 (20%)

Pixel Rate

The GeForce RTX 3060 Ti should be a little bit (approximately 10%) more effective at AA than the GeForce GTX 1080, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3060 Ti		112800 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 9952 (10%)

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 information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
