GeForce GTX 1660 Ti vs Radeon RX 590

Intro

The GeForce GTX 1660 Ti features a GPU core clock speed of 1500 MHz, and the 6144 MB of GDDR6 memory runs at 1500 MHz through a 192-bit bus. It also features 1536 SPUs, 96 Texture Address Units, and 48 ROPs.

Compare that to the Radeon RX 590, which has a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1660 Ti should perform a little bit faster than the Radeon RX 590 in general. (explain)

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

Texel Rate

The Radeon RX 590 is quite a bit (about 47%) more effective at anisotropic filtering 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 using high levels of AA is important to you, then the GeForce GTX 1660 Ti is a better choice, by far. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
