A few days ago, Samsung announced HBM4E sample shipment, a new high-bandwidth memory with massive speed gains and improved performance; in other words, this is a new money maker AI chip for the South Korean semiconductor firm.
HBM4E surpasses the initial HBM4 in different statistics, including 14Gbps stable in speed, performance increase up to 16Gbps for data processing. These numbers reflect up to 20% increase in performance over HBM4 introduced in February. The new AI chip delivers 3.6 TB/s memory bandwidth per stack for intensive computing for large language models (LLMs) and next-gen AI systems.
The initial version comes with 48GB (12-layer) capacity, a 30% increase over the last generation. The memory maker has a plan to add two other variants, a 32GB (8-layer) and 64GB (16-layer), based on customer demand.
This chip uses a low-power design with upto 16% energy efficiency and up to 14% thermal resistance than the previous generation.
The roadmap unfolded by HBM4’s mass production and industry success has led to the new chip, which will also enter the production line based on customer feedback for early samples.
Profit boom
This year brought the best business Samsung has ever recorded, thanks to the AI-chip boom. Its Q1 2026 result shows that Samsung posted KRW 133.9 trillion in revenue with a 43% quarter on quarter increase.
In other words, Samsung’s memory division posted an all-time high quarterly revenue. On the other hand, the KRW 53.7 trillion has been marked in operating profits, which is the highest the company has ever posted.
In Q1, the company became the second-largest semiconductor company in terms of operating profit, after Nvidia, which recorded around KRW 66 trillion. The sales doubled in the first quarter, and the operating profit saw more than a threefold increase.
Samsung said there are two reasons behind this rapid business increase. First is the HBM demand by key AI players, and the other is DRAM prices, which jumped up to 90% through past 12 months.
Besides, HBM4, the HBM4E is likely to get even more attention with its increased performance, which is necessary for the next-gen AI chips produced by the likes of Nvidia and AMD.
Samsung is expected to make new earnings records through 2026.
