The fact that the card is showcased at Computex 2023 suggests that Nvidia AIC partners are ready for launch and it might be that Nvidia is actually holding back the launch for some reason. The card in question was spotted by Hardware Unboxed, and it is MSI's Ventus 2X Black version, which is pretty identical to the RTX 4060 Ti 8GB Ventus 2X graphics card that has been launched. It has two fans and a rather small footprint making it suitable for SFF builds.

This is actually the first time that the RTX 4060 (non-Ti) has been pictured and it is officially coming in the first half of July, priced at $299.
