GeForce GTX 1660 Ti vs GeForce RTX 2070

Intro

Compare those specs to the GeForce RTX 2070, which comes with a GPU core clock speed of 1410 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 2070		175 Watts
	Difference: 55 Watts (46%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2070 is 56% faster than the GeForce GTX 1660 Ti in general, because of its higher bandwidth. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 163840 (56%)

Texel Rate

The GeForce RTX 2070 is quite a bit (approximately 41%) better at AF than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 59040 (41%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2070 is a better choice, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 18240 (25%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
