Nvidia is preparing the Geforce GTX 1060 3 GB with the GP104 graphics circuit

The launches of Geforce GTX 1080 and GTX 1070 took place around this year’s edition of the technology fair Computex 2016. Both graphics cards are equipped with the architecture Pascal and the circuit GP104, which later in the summer was joined by GP106 which lays the foundation for the middle class card GTX 1060.

The GP106 graphics circuit is a considerably smaller variant in terms of size, something that has a clear imprint in terms of specifications. The number of CUDA cores is halved compared to GP104, while the width of the memory bus is 192 instead of 256 bits. This has enabled Nvidia to push the price of the Geforce GTX 1060 compared to the GTX 1070 and GTX 1080.

It now appears that Nvidia is planning a new variant of the Geforce GTX 1060, as the slightly scaled-down variant with 1,152 CUDA cores and only 3 GB of GDDR5. This should be based on the defective GP104 circuits that do not meet the standard for use in GTX 1080 and GTX 1070.

This is reported by Videocardz, which has discovered a new identification loop in Nvidia’s drivers – NVIDIA_DEV.1B84 = “NVIDIA GeForce GTX 1060 3GB”. That it is the graphics circuit GP104 appears from the part “1B84”, where the first three characters are used to identify the GP104.

Graphics card	Circuit	CUDA cores	Memory amount
Geforce GTX 1080	GP104-400	2 560 st.	8 GB GDDR5X
Geforce GTX 1070	GP104-200	1 920 st.	8 GB GDDR5
Geforce GTX 1060	GP106-400	1 280 st.	6 GB GDDR5
Geforce GTX 1060	GP106-300	1 152 st.	3 GB GDDR5
Geforce GTX 1060	GP104-140	1 152 st.	3 GB GDDR5

The new variant of the graphics circuit is said to go under the name GP104-140, while GP104-200 is in the Geforce GTX 1070 and GP104-400 lays the foundation for GTX 1080. Despite another graphics circuit, both variants of the GTX 1060 (3 GB) should perform equally, however, it is expected variant with GP104-140 get slightly higher power consumption.

According to the same report, the odd variant of the Geforce GTX 1060 with 3 GB GDDR5 will not be sold globally, but will be exclusive to the Chinese market. Whether this will be the case remains to be seen as Nvidia has not yet released anything official about the new variant of the graphics card.
