GeForce GTX 650 Ti 2GB vs GeForce RTX 3080 Ti

Intro

Compare all that to the GeForce RTX 3080 Ti, which has a core clock frequency of 1365 MHz and a GDDR6X memory speed of 1188 MHz. It also uses a 384-bit bus, and uses a 8 nm design. It is comprised of 10240 SPUs, 320 Texture Address Units, and 112 Raster Operation Units.

	Difference: 847897 (981%)

Texel Rate

The GeForce RTX 3080 Ti will be a lot (about 635%) better at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 377408 (635%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3080 Ti is a better choice, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 138032 (930%)

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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
