GeForce GTX 1660 Ti vs Radeon RX 550

Intro

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

Compare all of that to the Radeon RX 550, which has a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
