An unusual engineering sample of the Nvidia GeForce RTX 3060 has been discovered, nearly five years after its official release. These pre-production prototypes are valuable because they offer a unique view into Nvidia’s internal development phase, revealing hardware configurations that never made it to the final product.

What makes this engineering sample remarkable is its specification. The sample, based on the Ampere architecture, is equipped with 3,840 CUDA cores, which is higher than the 3,584 CUDA cores of the final version released in February 2021 (with 12 GB of memory). This difference of 256 cores suggests that Nvidia’s initial plan may have aimed for a more powerful mid-range card.
In terms of clocks, the pre-production model also shows higher numbers: while the retail RTX 3060 had a boost clock around 1,777 MHz and a base clock of about 1,320 MHz, this prototype reaches up to 1,852 MHz in boost. The memory remains at 12 GB of GDDR6.
The discovery of this engineering sample model highlights how common it is for engineering units to differ from the final product: sometimes specs are cut back, and other times they were originally higher.
For the RTX 30 generation, which was a strong success for Nvidia, this sample serves as a reminder of “what could have been” in the mid-range segment.
