Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 45 Watts (60%)

Memory Bandwidth

Performance-wise, the GeForce GTX 1660 Ti should in theory be a lot better than the GeForce GTX 1630 overall. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 196608 (200%)

Texel Rate

The GeForce GTX 1660 Ti will be much (more or less 159%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 88320 (159%)

Pixel Rate

The GeForce GTX 1660 Ti is quite a bit (more or less 159%) more effective at FSAA than the GeForce GTX 1630, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 44160 (159%)

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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
