GeForce GTX 1660 Ti vs Radeon RX 5600 XT

Intro

The GeForce GTX 1660 Ti comes with a clock speed of 1500 MHz and a GDDR6 memory frequency of 12000 MHz. It also makes use of a 192-bit bus, and uses a 12 nm design. It features 1536 SPUs, 96 TAUs, and 48 ROPs.

Compare that to the Radeon RX 5600 XT, which comes with a core clock speed of 1375 MHz and a GDDR6 memory speed of 14000 MHz. It also makes use of a 192-bit memory bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
