GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 Ti has a core clock speed of 1607 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 16 nm design. It is made up of 2432 SPUs, 152 Texture Address Units, and 64 Raster Operation Units.

Compare all of that to the GeForce GTX 1660 Ti, which has core speeds of 1500 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 get to the max fill rate.
