GeForce GTX 1070 vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 uses a 16 nm design. nVidia has set the core speed at 1506 MHz. The GDDR5 RAM runs at a speed of 2000 MHz on this particular card. It features 1920 SPUs along with 120 TAUs and 64 ROPs.

Compare all of that to the GeForce GTX 1660 Ti, which has GPU clock speed of 1500 MHz, and 6144 MB of GDDR6 RAM set to run at 12000 MHz through a 192-bit bus. It also features 1536 Stream Processors, 96 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
