GeForce GTX 1660 Ti vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which comes with GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 ROPs.

GeForce GTX 1660 Ti		120 Watts
Radeon RX 590		175 Watts
	Difference: 55 Watts (46%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1660 Ti is 13% quicker than the Radeon RX 590 in general, due to its greater data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 590 is a lot (about 47%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 67536 (47%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is the winner, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 24992 (53%)

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 (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock 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 maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 maximum fill rate.
