GeForce GTX 1070 vs GeForce GTX 1660 Ti

Intro

Compare all of that to the GeForce GTX 1660 Ti, which comes with GPU core speed of 1500 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is comprised of 1536 Stream Processors, 96 Texture Address Units, and 48 Raster Operation Units.

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

Texel Rate

The GeForce GTX 1070 will be much (more or less 26%) better at anisotropic 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 a high resolution is important to you, then the GeForce GTX 1070 is a better choice, and very much so. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
