GeForce GTX 1070 vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 uses a 16 nm design. nVidia has clocked the core speed at 1506 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific card. It features 1920 SPUs as well as 120 TAUs and 64 Rasterization Operator Units.

Compare those specs to the GeForce GTX 1660 Ti, which uses a 12 nm design. nVidia has clocked the core speed at 1500 MHz. The GDDR6 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 get to the max fill rate.
