GeForce GTX 1660 Ti vs GeForce RTX 2080 Ti

Intro

The GeForce GTX 1660 Ti has core clock speeds of 1500 MHz on the GPU, and 12000 MHz on the 6144 MB of GDDR6 memory. It features 1536 SPUs along with 96 Texture Address Units and 48 ROPs.

Compare all of that to the GeForce RTX 2080 Ti, which has a clock frequency of 1350 MHz and a GDDR6 memory speed of 14 MHz. It also uses a 352-bit bus, and makes use of a 12 nm design. It is comprised of 4352 SPUs, 272 TAUs, and 88 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
