GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has set the core speed at 1607 MHz. The GDDR5 RAM is set to run at a frequency of 2000 MHz on this particular card. It features 2432 SPUs along with 152 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the GeForce GTX 1660 Ti, which comes with GPU core speed of 1500 MHz, and 6144 MB of GDDR6 memory running at 12000 MHz through a 192-bit bus. It also is made up of 1536 SPUs, 96 TAUs, and 48 Raster Operation Units.

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its 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 the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
