GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

The GeForce GTX 1660 Ti features a core clock frequency 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 is comprised of 1536 SPUs, 96 Texture Address Units, and 48 ROPs.

Compare that to the GeForce GTX 980 Ti, which comes with core speeds of 1000 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 RAM. It features 2816 SPUs along with 176 TAUs and 96 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
