Counterfeit GeForce RTX 4090 Cards with Plastic GPU Chips Surface in China

• June 19, 2026

Recent discoveries on the Chinese secondary market have unveiled a new type of counterfeit GeForce RTX 4090 graphics cards. Unlike previous counterfeit models that used rebranded GPU chips from older NVIDIA cards such as the GA102 processors from RTX 3080 or RTX 3090, these latest fake cards incorporate an unprecedented level of deception.

Plastic GPU Chips Replace Genuine Silicon

Instead of the authentic silicon GPU die, the counterfeiters behind this latest wave have resorted to installing plastic replicas of the graphics processing unit. This stark departure from prior methods points to an innovative, yet fraudulent tactic aimed at fooling buyers who may not immediately detect the absence of a real GPU chip.

Earlier counterfeit cards often relied on recycled or relabeled GPU dies taken from older generation GPUs, which could still offer limited functionality or at least convincingly mimic a working graphics card under some testing conditions. By contrast, the use of plastic GPU imitations on these new counterfeit RTX 4090 models signals a shift towards purely non-functional fakery, likely rendering the cards inoperable or severely diminished in capability.

This new counterfeit strategy poses significant risks for consumers, especially those attempting to procure high-end hardware from unofficial sellers in secondary markets. The genuine GeForce RTX 4090 is a flagship graphics card distinguished by its advanced performance and cutting-edge technology, making it a lucrative target for counterfeiters looking to capitalize on high demand.

The presence of plastic substitutes for GPU chips also highlights challenges in detecting counterfeit hardware. Traditional visual inspections and basic tests might fail to uncover these forgeries unless supported by detailed hardware diagnostics or verification through trusted vendors and channels.

While detailed information about the distribution scale and impact of these counterfeit cards remains limited, the emergence of plastic GPU chips marks a concerning development within the counterfeit GPU market segment. It underscores the importance of vigilance and due diligence when purchasing premium hardware, particularly in markets known for counterfeit electronics.

Consumers are advised to verify the authenticity of high-value GPU products through authorized retailers or directly from manufacturers to avoid falling victim to such sophisticated scams.
