GeForce GTX 1660 Ti vs Radeon RX 5600

Intro

The GeForce GTX 1660 Ti comes with a GPU core speed of 1500 MHz, and the 6144 MB of GDDR6 memory runs at 12000 MHz through a 192-bit bus. It also features 1536 SPUs, 96 TAUs, and 48 Raster Operation Units.

Compare those specifications to the Radeon RX 5600, which comes with a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM set to run at 12000 MHz through a 192-bit bus. It also features 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
Radeon RX 5600 150 Watts
Difference: 30 Watts (25%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 5600 should be much (approximately 22%) more effective at texture filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 5600 176000 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 32000 (22%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5600 is a better choice, by far. (explain)

Radeon RX 5600 88000 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 16000 (22%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
