GeForce GTX 650 Ti vs GeForce RTX 3080 12 GB

Intro

Compare that to the GeForce RTX 3080 12 GB, which uses a 8 nm design. nVidia has clocked the core frequency at 1260 MHz. The GDDR6X memory works at a speed of 1188 MHz on this specific card. It features 8960 SPUs as well as 280 Texture Address Units and 112 ROPs.

GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 293408 (494%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 12 GB is superior to the GeForce GTX 650 Ti, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 126272 (850%)

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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
