The Rise of Desktop Graphics Cards in China: Nvidia RTX 4080M


The transformation of dedicated graphics processing units (GPUs) from laptops into desktop graphics cards is a growing phenomenon in China. Unknown companies are manufacturing and releasing these cards with professional and attractive designs, supporting both Nvidia and AMD graphics. One notable example is the Nvidia RTX 4080M, originally designed for laptops but now making waves as a desktop graphics card.

The Process of Transformation

Chinese companies extract GPU units like AD104 and AD103 from laptop printed circuit boards (PCBs) and install them on larger PCBs used for desktop graphics cards. This process is exemplified by the RTX 4080M and RTX 4090M, derived from their laptop counterparts.

Performance Considerations

Despite concerns about manufacturing quality from these unknown GPU makers, the primary consideration is the performance level. When purchasing an RTX 4080M, it's essential to note that its performance lies between the RTX 4070 and RTX 4070 Ti desktop graphics cards. The reason behind this lies in the lower number of compute units in the RTX 4080M's AD104 GPU compared to the AD103 in the RTX 4080.

Power Consumption and Efficiency

The RTX 4080M boasts a power consumption rate of 285 watts, lower than the RTX 4080's 320 watts. This efficiency extends to the RTX 4090M, emphasizing the trade-off between performance and power consumption.

Challenges and Considerations

While these cards may seem appealing due to their lower prices, two critical issues arise. Firstly, these graphics cards lack a confirmed warranty, given their origin from unknown Chinese manufacturers. Secondly, being originally designed for laptops, these cards have specific drivers, potentially affecting user experience with games or software and possibly leading to compatibility issues with the card, drivers, and operating systems.

Q&A Section

Q1: Are these Chinese-manufactured desktop graphics cards reliable?

A1: The reliability of these cards is a concern due to the unknown manufacturers and the absence of confirmed warranties.

Q2: What is the performance difference between the RTX 4080M and its desktop counterpart, the RTX 4080?

A2: The RTX 4080M's performance is between the RTX 4070 and RTX 4070 Ti, falling short of the desktop RTX 4080 due to differences in the GPU's compute units.

Q3: How does the power consumption of the RTX 4080M compare to the desktop RTX 4080?

A3: The RTX 4080M has a lower power consumption of 285 watts compared to the desktop RTX 4080's 320 watts.


While the trend of transforming laptop GPUs into desktop graphics cards is gaining traction in China, potential buyers must weigh the advantages of lower prices against the risks associated with unknown manufacturers and potential compatibility issues.
