A closer look at the gtx 1660 ti gpu, smaller than tu106
Table of contents:
This is the first image of NVIDIA's 12nm " TU116 " silicon, which powers the upcoming GeForce GTX 1660 Ti graphics card.
The GPU of the GTX 1660 Ti is exposed
While the size of the package itself is identical to that of the " TU106 " on which the RTX 2060 and RTX 2070 are based, the matrix of the TU116 is visibly smaller. This is because the chip physically lacks RT cores, and only has two thirds of the CUDA cores than the TU106, with 1, 536 compared to 2, 304 for the latter. The area of the matrix, too, is approximately 2/3 of that of the TU106. The ASIC version of the TU116 that powers the GTX 1660 Ti is “ TU116-400-A1. ”
The source obtained not only images from the ASIC, but also the printed circuit board from an MSI GTX 1660 Ti Ventus graphics card, which reveals something very interesting. The PCB has traces for eight memory chips, through a 256-bit wide bus, although only six of them are populated with memory chips, which represent 6 GB on a 192-bit bus.
TU116 and TU106 face to face
NVIDIA is likely using a common substrate, with an identical pinmap between the TU106 and TU116, so this could reduce PCB development costs by different manufacturing partners. The similarities end here between both GPUs, and it is not the same cut chip (as it was speculated), but they are visibly different, as can be seen in the image above.
The GTX 1660 Ti would be announced on February 22.
