GeForce GTX 660 Ti vs GeForce RTX 2080 SUPER

Intro

Compare those specs to the GeForce RTX 2080 SUPER, which comes with a GPU core clock speed of 1650 MHz, and 8192 MB of GDDR6 memory set to run at 1937 MHz through a 256-bit bus. It also is made up of 3072 Stream Processors, 192 Texture Address Units, and 64 ROPs.

GeForce GTX 660 Ti		144000 MB/sec
	Difference: 363904 (253%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (approximately 209%) more effective at texture filtering than the GeForce GTX 660 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 214320 (209%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is superior to the GeForce GTX 660 Ti, by a large margin. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 83640 (381%)

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 (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
