GeForce GTX 1660 Ti vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this card. It features 1344 SPUs as well as 112 TAUs and 32 ROPs.

GeForce GTX 1660 Ti		120 Watts
Geforce GTX 670		170 Watts
	Difference: 50 Watts (42%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti is 54% faster than the Geforce GTX 670 overall, due to its greater data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 102912 (54%)

Texel Rate

The GeForce GTX 1660 Ti will be quite a bit (more or less 41%) more effective at texture filtering than the Geforce GTX 670. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 41520 (41%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 1660 Ti is superior to the Geforce GTX 670, by far. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 42720 (146%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
