GeForce GTX 1070 Ti vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1070 Ti features core clock speeds of 1607 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2432 SPUs along with 152 TAUs and 64 Rasterization Operator Units.

Compare all of that to the GeForce GTX 1660 Ti, which comes with a clock frequency of 1500 MHz and a GDDR6 memory frequency of 12000 MHz. It also uses a 192-bit memory bus, and makes use of a 12 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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