GeForce GTX 1660 Ti vs Radeon RX 5600 XT

Intro

The GeForce GTX 1660 Ti features a core clock speed of 1500 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and makes use of a 12 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 48 ROPs.

Compare that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 RAM is set to run at a speed of 1500 MHz on this model. It features 2304 SPUs as well as 144 Texture Address Units and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 Render Output Units by the the card's clock speed. 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 fill rate also depends 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 maximum fill rate.
