GeForce GTX 1660 Ti vs Radeon RX 5600

Intro

Compare all of that to the Radeon RX 5600, which features clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator 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 theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 5600 is a lot (about 22%) more effective at anisotropic 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 running with a high screen resolution is important to you, then the Radeon RX 5600 is a better choice, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
