RTX 5080 24GB Reportedly Cut: 3x GDDR7 Cost [2026] - shattered.io

According to reports from Board Channels, tracked by multiple tech outlets including PC Guide and Overclock3D, Nvidia informed its graphics card partners that a planned January 2027 launch of the RTX 5080 24GB in China has been cancelled. The company provided no replacement date for the higher-capacity variant. The stated reason for the cancellation is the prohibitive cost of 3GB GDDR7 memory chips, which reportedly cost approximately three times more than the 2GB chips used in the current 16GB model.

Memory Cost Math

The reported design would have replaced eight 2GB GDDR7 chips with eight 3GB chips on the same 256-bit memory bus, increasing capacity from 16GB to 24GB. While this represents a 50% capacity increase, the memory cost would have tripled. If a 2GB chip costs P, eight would cost 8P, while eight 3GB chips would cost 24P. This would double the cost per gigabyte of memory, making the retail price unsustainable for a card already priced at $999.

China Market Focus

The cancellation specifically affects the China launch, suggesting Nvidia was targeting local AI hobbyists and small studios who need more than 16GB but can't afford workstation-grade solutions. This regional approach aligns with China's growing market for local AI model development. Nvidia's broader China position faces challenges, with its market share reportedly slipping to 34% in the data-center segment.

Industry Impact

The cancellation reflects broader memory supply constraints affecting the entire GPU market. Recent reports show RTX 5070 Ti prices jumping 79% above MSRP and RTX 5090 cards ranging from $1,999 to $5,000. Phone manufacturers are also affected, with reballed RAM reaching 3-4% of budget phones as new memory becomes scarce or expensive.

For buyers, the immediate effect is minimal - the 16GB RTX 5080 remains available. For board partners, the cancellation means wasted design resources and a gap in their product lineup. AMD may benefit from this move, as their Radeon cards have traditionally offered generous memory at competitive price points.
