GeForce GTX 1660 Ti vs Radeon RX 5600

Intro

The GeForce GTX 1660 Ti features a GPU core clock speed of 1500 MHz, and the 6144 MB of GDDR6 RAM is set to run at 1500 MHz through a 192-bit bus. It also features 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the Radeon RX 5600, which has a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is made up of 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 the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 5600 is a lot (more or less 22%) faster with regards to AF 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

The Radeon RX 5600 is a lot (about 22%) faster with regards to FSAA than the GeForce GTX 1660 Ti, and also should be capable of handling higher resolutions more effectively. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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.
