GeForce GTX 1660 Ti vs GeForce RTX 2060

Intro

Compare all that to the GeForce RTX 2060, which has GPU clock speed of 1365 MHz, and 6144 MB of GDDR6 memory running at 1750 MHz through a 192-bit bus. It also is comprised of 1920 SPUs, 120 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 2060		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should be 17% faster than the GeForce GTX 1660 Ti in general, because of its greater data rate. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 49152 (17%)

Texel Rate

The GeForce RTX 2060 will be a little bit (about 14%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 19800 (14%)

Pixel Rate

The GeForce GTX 1660 Ti will be a little bit (approximately 10%) more effective at full screen anti-aliasing than the GeForce RTX 2060, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 6480 (10%)

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 data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
