GeForce GTX 1070 vs GeForce GTX 1660 Ti

Intro

Compare all that to the GeForce GTX 1660 Ti, which makes use of a 12 nm design. nVidia has set the core speed at 1500 MHz. The GDDR6 memory is set to run at a frequency of 1500 MHz on this model. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

GeForce GTX 1660 Ti		120 Watts
GeForce GTX 1070		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti should be 13% quicker than the GeForce GTX 1070 in general, due to its greater data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce GTX 1070		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The GeForce GTX 1070 should be much (about 26%) faster with regards to texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce GTX 1070		180720 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 36720 (26%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1070 is a better choice, by far. (explain)

GeForce GTX 1070		96384 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 24384 (34%)

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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
