	Difference: 25088 (9%)

Texel Rate

The GeForce GTX 1660 Ti will be a little bit (about 2%) better at texture filtering than the Radeon R9 290X. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 290X		140800 Mtexels/sec
	Difference: 3200 (2%)

Pixel Rate

The GeForce GTX 1660 Ti should be much (approximately 41%) faster with regards to FSAA than the Radeon R9 290X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 290X		51200 Mpixels/sec
	Difference: 20800 (41%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
