Modified RTX 5090 96GB Appears on Alibaba for $3,888

A high-capacity modified graphics card has been confirmed on the Chinese market. According to reporting by Zhiye Liu of Tom’s Hardware, China’s Shenzhen Suqiao Intelligent Technology listed a 96GB version of the RTX 5090 on Alibaba. Priced at $3,888, it offers three times the memory capacity of the official product. The move has renewed attention on modified cards driven by demand for AI applications.

Overview of the 96GB Modified Card Listed

on Alibaba

The seller on Alibaba is Shenzhen Suqiao Intelligent Technology Co., Ltd. The company is an OEM/ODM handling graphics boards, substrates, and servers, with reportedly more than 10 years in business. What makes this case notable is that it involves a company with an established manufacturing track record, not an unknown small workshop. The listing price is $3,888, described as 35% cheaper than the standard edition in the United States. The headline claims three times the memory capacity at 65% of the cost of the genuine product.

The product is a modified version based on Nvidia’s top-end Blackwell-generation product. The standard edition has 32GB of memory, so 96GB is three times that amount. The listing reportedly also includes references to GDDR6X and 14Gbps. Since the actual Blackwell generation uses GDDR7, questions remain about the accuracy of the listing. The specification table should not be taken at face value.

The fact that the sales channel is Alibaba should not be overlooked. The marketplace focuses on business-to-business transactions, and guarantees of operation and support systems vary by seller. Buyers should not judge on price alone and must check the terms. It is important to understand how the capacity increase works and its technical background.

How Custom PCB Design Enables the Larger Capacity

The technical basis for a 96GB configuration lies in the existing product lineup. The RTX Pro 6000 Blackwell carries 96GB of GDDR7 and uses the same GB202 die. That product differs in having more enabled compute units. Still, it confirms that 96GB is feasible with the GB202 die. That is one piece of evidence supporting the existence of the modified card.

The key is a custom PCB and double-sided mounting. Memory chips are placed on both the front and back of the board, doubling the installed capacity. The GB202 is said to have 32 mounting sites. The RTX Pro 6000 Blackwell achieves 96GB by using 32 chips of 24Gb, or 3GB each. The modified card likely secures its capacity with the same combination.

Several routes are conceivable for sourcing the dies. One is obtaining GB202 dies individually. Another is removing dies from standard products and remounting them on a custom PCB. Either approach requires process control different from mass-produced goods. Thermal and power designs must also be readjusted. Stable operation depends directly on the quality of the PCB design.

Simply adding more memory chips is not enough to increase capacity. Ensuring signal integrity and controlling heat become challenges. Double-sided mounting requires a revised cooling structure. Driver recognition and error-handling behavior must also be verified. For corporate use, long-duration operation testing is a prerequisite.

The Lineage of Modified GPUs Born from AI Demand

This modification is not a one-off experiment. Chinese factories have continued to increase the capacity of existing products amid growing AI demand. In the past, a 32GB version of the RTX 5080 was reported. 48GB versions of the RTX 4090 and 48GB versions of the RTX 3090 have also appeared. Curiosity-driven prototypes and products aimed at real demand have coexisted.

Behind this is demand for environments to run generative AI and large language models. In training and inference, memory capacity determines the scale that can be processed. Large memory is especially effective for holding weights during inference. In 3D processing such as Streaming 3D Reconstruction Achieves SOTA with Geometric Context Transformer, memory capacity also affects processing efficiency. In workplaces handling images and video, insufficient capacity can interrupt work. These practical needs have sustained the modification market.

Meanwhile, rumors of a 128GB version have also circulated. The current 96GB model is considered more technically consistent than the 128GB claim. The commonality with the RTX Pro 6000 Blackwell is the basis for that assessment. A capacity configuration with precedent is also easier to verify. In terms of feasibility, it is positioned differently from previous rumors.

Compute demand is also expanding on mobile devices. As shown by Snapdragon Reality Elite, New Chip for AR/MR, graphics processing infrastructure is being strengthened for augmented and mixed reality as well. Desktop high-performance products and efficiency-focused mobile products play different roles. Even so, demand for large-capacity memory is growing across both. The emergence of modified cards reflects this demand structure.

Price Gap vs.

Official Product and Purchase Cautions

The price appeal is clear. At $3,888, it is said to be 35% cheaper than the standard edition. With three times the memory capacity, the cost per unit of capacity differs greatly. It looks attractive for AI experimentation and testing. It broadens options for organizations with budget constraints.

However, the availability of an official warranty is a critical issue. Modified cards are highly likely to fall outside Nvidia’s official warranty. Buyers must check the seller’s warranty terms and coverage. Repair systems and parts supply in case of failure are also unclear. For long-term operation, this is a risk factor.

Compatibility and operational checks are also essential. With a custom PCB, compatibility of cooling components changes. Fit inside the case and power supply capacity must also be considered. Driver updates could change how the card is recognized. Pre-deployment testing cannot be skipped.

Establishing a testing system is also a challenge. As discussed in GNOME OS Test Center, Inspired by Apple TestFlight, pre-distribution testing infrastructure is directly linked to quality assurance. For modified products, shipping inspection standards are rarely disclosed. Designing acceptance tests on the buyer’s side is important. Load testing, temperature measurement, and long-duration operation tests are required. Buyers need to keep records and ensure reproducibility.

Market Impact and Key Points to Watch

In the short term, interest is likely to grow for testing purposes and at small and mid-sized development sites. Official high-capacity products are expensive and subject to procurement constraints. Modified cards fill that gap. They will also affect price formation in the used market. If circulation increases, demand for peripheral components will also shift.

In the medium term, the focus will be on the impact on product strategy. Chipmakers segment the market by combining compute performance and memory capacity. The spread of modified cards shakes up that segmentation. It could prompt larger capacities for official products and revisions to pricing structures. Stronger supply management and distribution controls are also conceivable.

On the technical side, the quality of the double-sided implementation will be tested. Balancing signal integrity and thermal measures is key to stability. Whether design documentation and test results for the custom PCB will be disclosed is a point to watch. Third-party teardown analyses and load measurements are awaited. Fact-based evaluations need to accumulate.

Editorial Opinion

In terms of short-term impact, we expect this listing to change procurement for testing purposes over the next three to six months. We assess that the low cost per unit of capacity will encourage experimentation by small development organizations. If supply constraints on official products continue, circulation of modified cards will temporarily expand. However, given remaining concerns over warranty and compatibility, it is reasonable to see application in production environments as limited.

From a long-term perspective, we expect product segmentation centered on memory capacity to be reorganized over the next one to three years. We assess that chipmakers will strengthen their offerings of official high-capacity products. The existence of the modification market will put pressure on pricing and supply. On the user side, acceptance testing and operational records will become more important. We assess that experience with non-official products will lead to clearer procurement standards.

Questions from the editorial team: Will sufficient verification data be disclosed to prove stable operation? We see temperature and error-rate measurements during long-duration operation as key questions. Will recognition and performance be maintained after driver updates? We also see the seller’s support system and continuity of parts supply as open questions. We assess that the central issue is how to balance price appeal against operational risks.
