GeForce GTX 1660 Ti vs GeForce RTX 4090

Intro

Compare all of that to the GeForce RTX 4090, which has a GPU core clock speed of 2235 MHz, and 24576 MB of GDDR6X memory set to run at 1325 MHz through a 384-bit bus. It also is made up of 16384 SPUs, 512 Texture Address Units, and 176 Raster Operation Units.

	Difference: 747520 (253%)

Texel Rate

The GeForce RTX 4090 will be quite a bit (more or less 695%) more effective at anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 1000320 (695%)

Pixel Rate

The GeForce RTX 4090 should be much (about 446%) more effective at FSAA than the GeForce GTX 1660 Ti, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 4090		393360 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 321360 (446%)

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 (measured in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
