NVIDIA GeForce GTX 1660 and 1660 Ti Memory, Clock Speeds and More

This is an odd post. You are going to be reading a collaborative effort of leaks containing information from my own sources as well as information that has appeared on the internet before – in which case the credit has been given to the respective sources – Tom’s Hardware Germany and VideocardZ. There are also some new details in the mix that I will be throwing in – such as the clock speed, memory specifications, and PCB details. I have split the article into two parts: confirmed and (educated) speculation. Let’s begin with the facts.

The GeForce GTX 1660 will have 6GB GDDR5 memory

The GeForce GTX 1660 will have 6GB of GDDR5 memory with a 192-bit bus. The memory will be clocked at 4000 MHz while the clock speed will be 1530 MHz base and 1785 MHz boost. The card will feature the TU116-300 die and the board number is PG165.

The GeForce GTX 1660 Ti will have 6GB GDDR6 memory and the same board as the RTX 2060

The 1660 Ti, on the other hand, will have 6GB of GDDR6 memory and a 192-bit bus. This will be clocked at 6000 MHz which is considerably faster than the 1660 counterpart. The base clock will be 1500 MHz with boost at 1770 MHz. The card is based on the TU116-400 die and the board number is PG161 – which is the same board number as the RTX 2060. This also means the die will be pin compatible with the 2060.

Both cards will be launching sometime around Valentines Day (Feb 14).

Interpreting this new data

If you are here for verified and confirmed information, this is where you stop reading.

The fact that the GTX 1660 Ti is the same board number as the RTX 2060 means that we are probably looking at the tensor and RTX cores disabled via hardware straps. It is also worth noting that a 3GB version of the GTX 1660 is also being planned – with 3GB of GDDR5 memory and 4000 MHz clocks.

The core counts leaked by VCZ put the NVIDIA GeForce GTX 1660 Ti and GTX 1660 at 5.44 TFLOPs and 4.57 TFLOPs respectively. In comparison, the RTX 2060 is going to be 6.45 TFLOPs. The ROP counts can also be inferred using these core count specifications. The GTX 1660 Ti should be priced somewhere around the $279 mark and a good enough price point could make this the new entry-level champion. With these specs, you are looking at 1070-or-more level performance.
