GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

The GeForce GTX 1660 Ti features a GPU core clock speed of 1500 MHz, and the 6144 MB of GDDR6 RAM runs at 1500 MHz through a 192-bit bus. It also is made up of 1536 Stream Processors, 96 Texture Address Units, and 48 ROPs.

Compare those specs to the GeForce GTX 980 Ti, which has GPU core speed of 1000 MHz, and 6144 MB of GDDR5 RAM running at 1750 MHz through a 384-bit bus. It also is made up of 2816 SPUs, 176 TAUs, and 96 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
