GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 Ti features a GPU core speed of 1607 MHz, and the 8192 MB of GDDR5 RAM is set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2432 SPUs, 152 TAUs, and 64 Raster Operation Units.

Compare those specs to the GeForce GTX 1660 Ti, which features a clock frequency of 1500 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and uses a 12 nm design. It is made up of 1536 SPUs, 96 TAUs, and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
