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 frequency at 1500 MHz. The GDDR6 memory runs at a speed of 1500 MHz on this model. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

Texel Rate

The GeForce GTX 1070 is quite a bit (approximately 26%) more effective at 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

The GeForce GTX 1070 will be a lot (more or less 34%) faster with regards to anti-aliasing than the GeForce GTX 1660 Ti, and will be able to handle higher resolutions without slowing down too much. (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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 memory bandwidth is, the lower the potential to get to the max fill rate.
