Radeon R9 380 4G		182400 MB/sec
	Difference: 112512 (62%)

Texel Rate

The GeForce GTX 1660 Ti is quite a bit (approximately 33%) more effective at texture filtering than the Radeon R9 380 4G. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 35360 (33%)

Pixel Rate

The GeForce GTX 1660 Ti will be a lot (more or less 132%) more effective at AA than the Radeon R9 380 4G, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 380 4G		31040 Mpixels/sec
	Difference: 40960 (132%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
