On July 30, 2026, NVIDIA, the global AI chip leader, officially unveiled its next-generation AI accelerator chip, the Blackwell B200, at its annual GPU Technology Conference in San Jose. Based on TSMC's advanced N3E process, it integrates high-bandwidth memory HBM4 for the first time, delivering approximately 3x the compute power and 2.5x the energy efficiency of its predecessor, the Hopper H100. The news triggered an immediate reaction in the global semiconductor market: memory chip prices rose, Samsung Electronics and SK Hynix shares surged over 5% in a single day, and TSMC's 3nm capacity utilization climbed above 100%.
Blackwell B200 Technical Highlights: Synergistic Breakthrough of 3nm Process and HBM4
Blackwell B200 is NVIDIA's new flagship AI chip after the Hopper architecture, designed for large language models, generative AI, and inference tasks. Its core specs include 208 billion transistors, TSMC N3E process (equivalent to 3nm), and core frequency over 2.5 GHz. Most notably, B200 is the first to support HBM4 memory, offering total bandwidth up to 4.8 TB/s and capacity of 288 GB, double that of H100 (HBM3).
HBM4 is the next-generation high-bandwidth memory standard, officially released by JEDEC in 2025, with a single stack bandwidth up to 1.6 TB/s and support for 24-layer stacking. Samsung, SK Hynix, and Micron have all mass-produced HBM4 products. The launch of B200 marks the large-scale application of HBM4 in AI training and inference scenarios, expected to consume over 70% of global HBM4 capacity in the second half of 2026.
Supply-Demand Imbalance Intensifies: HBM4 Prices Surge, Wafer Foundry Capacity Strains
The launch of Blackwell B200 directly triggered supply-demand tension in the memory chip market. According to the latest report from market research firm TrendForce, on July 30, the spot price of HBM4 (12-layer stack) rose 12% from the previous day to about $15 per GB, hitting a record high. Meanwhile, DDR5 memory and NAND Flash prices also rose by 3% and 2%, respectively.
In wafer foundry, TSMC, the sole foundry for B200, saw its 3nm line (N3E) utilization rate increase from 95% in Q2 to 105% (overloaded). TSMC plans to increase 3nm capacity by 15% in Q4 2026, but new capacity will mainly be allocated to NVIDIA and Apple. Other customers like AMD and MediaTek may face 3nm capacity squeeze risks.
In the packaging stage, B200 uses TSMC's CoWoS-L advanced packaging, imposing high integration requirements for HBM4. Currently, TSMC's CoWoS capacity gap is about 20%, with lead times extended to over 6 months. NVIDIA has locked in 60% of TSMC's total CoWoS capacity for 2026, leaving limited capacity for other AI chip makers.
Semiconductor Market Outlook: AI Chips Drive a New Round of Price Hikes
The launch of NVIDIA's B200 not only boosted capital market sentiment but also had a tangible impact on the physical semiconductor market. Historically, after the Hopper H100 launch, HBM3 prices accumulated an 80% increase from Q3 2023 to Q2 2024. This round of HBM4 price hikes may last longer due to more complex HBM4 manufacturing and slow yield ramp-up.
Industry analyst firm Gartner expects the global AI chip market to exceed $120 billion in 2026, with NVIDIA holding over 80% share. In the second half of 2026, AI-related chips (including GPU, HBM, CoWoS) will account for over 35% of total global semiconductor demand, pushing the overall chip average selling price (ASP) up by 10%-15%.
However, price hikes may also dampen demand from some SMEs. Many cloud computing providers have already started stockpiling, but some AI startups facing cost pressures may turn to more cost-effective alternatives like AMD's MI400 or Intel's Gaudi 3.
Vietnam Semiconductor Investment Opportunities: Tapping into AI Chip Supply Chain
For Vietnam's semiconductor industry, the supply chain restructuring triggered by NVIDIA's B200 launch presents new opportunities. Vietnam currently has a certain foundation in electronics manufacturing and packaging testing but has yet to enter HBM and advanced process foundry. However, as global supply chain diversification accelerates, Vietnam is attracting memory packaging and PCB manufacturing investments.
In July 2026, the Vietnamese government approved a five-year semiconductor industry promotion plan, investing $5 billion to build a packaging and testing base, targeting local HBM packaging by 2028. Additionally, Samsung Electronics is expanding its packaging plant in Bac Ninh Province, expected to start production in 2027, taking on some HBM4 packaging orders. This creates conditions for Vietnam to attract foreign direct investment (FDI) in AI chip packaging.
For investors, it is recommended to focus on semiconductor packaging and testing companies operating in Vietnam, as well as companies supplying substrates, thermal modules, and other components for AI chips. Local PCB manufacturers such as Viettronics and PTV Electronics may benefit from increased demand for high-layer PCBs for AI chips.
Risk Warnings and Future Focus
Despite the bullish AI chip market, caution is needed regarding the following risks: first, geopolitical risks—if the U.S. further expands export controls on semiconductor equipment to China, it could affect TSMC's 3nm capacity expansion; second, HBM4 yield improvement may fall short of expectations, slowing supply release; third, AI compute demand may experience a phased slowdown, and if large model training growth decelerates, chip price momentum could weaken.
In the next six months, closely monitor the following indicators: TSMC monthly revenue, HBM4 memory contract prices, initial shipment volume of NVIDIA B200, and the HBM4 new product progress of Samsung and SK Hynix. These data will directly influence the short-term direction of the semiconductor market.
Overall, the launch of NVIDIA's Blackwell B200 marks the entry of AI chips into the 3nm+HBM4 era, ushering in a new round of structural price increases in the semiconductor market. The supply-demand dynamics in the three key segments—memory chips, wafer foundry, and advanced packaging—will remain tight, offering investment opportunities worth exploring. Vietnam Investment News will continue to provide timely and in-depth semiconductor market analysis for investors.
