NVIDIA allegedly cancels its December launch of GeForce RTX 3080 20GB and RTX 3070 16GB. This still very fresh information comes from two independent sources.
Technically GeForce RTX 3080 20GB and RTX 3070 16GB could launch at a later time, but the information that we have clearly stated that those SKUs have been canceled, not postponed. NVIDIA has already canceled its RTX 3070 Ti model (PG141 SKU 0), so the RTX 3070 16GB (PG141 SKU5) and RTX 3080 20GB (PG132 SKU20) will be joining the list.
The GeForce RTX 3080 20GB was expected to be a response to AMD Radeon RX 6900/6800 series featuring Navi 21 GPU. All three AMD SKUs will feature 16GB of memory, leaving NVIDIA with a smaller frame buffer to compete with.
We do not know the official reason for the cancellation. The RTX 3080 20GB might have been scrapped due to low GDDR6X yield issues, one source claims. The reason behind RTX 3070 16GB cancellation is unknown (this SKU uses GDDR6 memory).
The plans for GeForce RTX 3060 Ti remain unchanged. The PG190 SKU 10 remains on track for mid-November launch. NVIDIA has not yet confirmed the exact launch date.
