GeForce GTX 1660 Ti vs GeForce RTX 3080

Intro

Compare those specs to the GeForce RTX 3080, which uses a 8 nm design. nVidia has set the core frequency at 1440 MHz. The GDDR6X RAM works at a speed of 1188 MHz on this card. It features 8704 SPUs along with 272 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 3080		320 Watts
	Difference: 200 Watts (167%)

Memory Bandwidth

In theory, the GeForce RTX 3080 should perform quite a bit faster than the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 483635 (164%)

Texel Rate

The GeForce RTX 3080 is a lot (about 172%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 247680 (172%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 is the winner, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 66240 (92%)

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 data (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
