GeForce GTX 1070 vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 features a GPU core clock speed of 1506 MHz, and the 8192 MB of GDDR5 memory is set to run at 2000 MHz through a 256-bit bus. It also features 1920 Stream Processors, 120 Texture Address Units, and 64 ROPs.

Compare those specifications to the GeForce GTX 1660 Ti, which comes with GPU clock speed of 1500 MHz, and 6144 MB of GDDR6 RAM running at 12000 MHz through a 192-bit bus. It also features 1536 Stream Processors, 96 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
