Since NVIDIA has multiple embargoes on RTX 3060 SKU, some of which have already expired. According to the latest rumors that we have received, NVIDIA currently plans to seed GeForce RTX 3060 review samples through its partners on February 19th.
Earlier rumors have suggested that NVIDIA might launch its RTX 3060 at the end of February, however, since the review seeding will begin on the 19th, it seems reasonable to expect at least a week for reviews to be prepared. Therefore the RTX 3060 would indeed launch in the last week of February.
It seems that NVIDIA has not yet provided the final dates. NVIDIA might just be playing a safe card in case there are any delays in GA106 production. After all, this is the first time we will be seeing products based on this graphics processor.
