Supply chain insiders reckon that stock of NVIDIA's "Ada Lovelace" generation GeForce RTX 4070 GPU will be depleted by the end of this month. This revelation emerges on the cusp of Team Green's GeForce RTX 5000 series of "Blackwell" GPUs heading to market (on January 30). The popular Chinese hardware forum—Board Channels—is a reliable source of product "supply and demand" information. Industry insiders believe that Team Green's mid-tier SKU will be completely sold—by the closing of this month—across several unnamed regional markets. NVIDIA's incoming GeForce RTX 5070 SKU (baseline $549 MSRP) appears to be the natural alternative, given that GeForce RTX 4070 SUPER offerings are priced within the range of $550 - $600—according to market research performed by VideoCardz.

A board member disclosed details and prophesized changes up and down NVIDIA's current-gen product stack: "The inventory for NVIDIA RTX 4070 and higher models is expected to be completely cleared by January. Starting from February, major AIC brands are anticipated to have stock remaining only for the RTX 4060 Ti and RTX 4060 series, which still need to be digested. However, since NVIDIA's Q1 begins in February, these two models will essentially enter the final stock phase." VideoCardz anticipates a March launch window for the GeForce RTX 5060 series—this could be well-timed given circumstances surrounding Team Green's (alleged) limiting of GeForce RTX 4060 Ti GPU supplies and the insider's predicted cessation of RTX 4060 (non-Ti) production.
 
I would say this seems to be reasonable information.
