GeForce GTX 660 Ti vs GeForce RTX 3090

Intro

Compare all of that to the GeForce RTX 3090, which comes with GPU clock speed of 1395 MHz, and 24576 MB of GDDR6X memory running at 1219 MHz through a 384-bit bus. It also features 10496 Stream Processors, 328 TAUs, and 112 ROPs.

GeForce GTX 660 Ti		144000 MB/sec
	Difference: 814668 (566%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (about 346%) faster with regards to texture filtering than the GeForce GTX 660 Ti. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 355080 (346%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3090 is the winner, by far. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 134280 (611%)

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 information (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
