GeForce GTX 1660 Ti vs Radeon RX 590

Intro

The GeForce GTX 1660 Ti uses a 12 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 RAM is set to run at a frequency of 12000 MHz on this specific model. It features 1536 SPUs along with 96 Texture Address Units and 48 Rasterization Operator Units.

Compare all that to the Radeon RX 590, which features 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX 1660 Ti, in theory, should perform just a bit faster than the Radeon RX 590 overall. (explain)

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

Texel Rate

The Radeon RX 590 should be quite a bit (more or less 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 running with a high resolution is important to you, then the GeForce GTX 1660 Ti is a better choice, 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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
