# Samsung said it began HBM4 mass production and commercial shipment Samsung said on February 12, 2026 that it began HBM4 mass production and commercial shipment, with stated 12-high capacity, I/O and bandwidth figures for AI systems. Canonical: https://rangoon.ai/insights/archive-samsung-hbm4-commercial-shipment-february-2026/ Author: Rangoon Editorial (https://rangoon.ai/insights/editorial/) Published: 2026-10-24 Updated: 2026-10-24 Event date: 2026-02-12 Tags: [HBM4](https://rangoon.ai/insights/tags/hbm4/), [AI memory](https://rangoon.ai/insights/tags/ai-memory/), [advanced packaging](https://rangoon.ai/insights/tags/advanced-packaging/) Source note: Historical reporting: Samsung's February 12, 2026 release says it began HBM4 mass production and shipped commercial products. Samsung's public HBM4 product page was freshly read for component detail. All yield, performance, efficiency and industry-first statements remain Samsung claims; no customer qualification or system throughput is asserted. Image: HBM4 package-to-accelerator boundary.

No vendor interface, photograph, measurement result, or endorsement implied. ## Key takeaways - Samsung's February record describes commercial HBM4 shipment, distinct from a sample or future-ramp announcement. - The company published 12-high capacity, 2,048-I/O and up-to-3.3-TB/s figures for its component. - Memory-component performance does not establish accelerator throughput, customer qualification or shipped-system behavior. ## Samsung described mass production and commercial shipment as the February event [source 1](https://news.samsung.com/global/samsung-ships-industry-first-commercial-hbm4-with-ultimate-performance-for-ai-computing) [source 2](https://semiconductor.samsung.com/dram/hbm/hbm4/) Samsung's February 12, 2026 newsroom release says it began mass production of HBM4 and shipped commercial products to customers. That status is distinct from the HBM4 samples and future supply plans already common in the market: it is Samsung's own commercial-shipment statement. The company calls the product industry-leading and describes stable yields; both are supplier claims. The release does not identify customers, volumes, qualification criteria or an accelerator model, so it cannot establish a customer deployment or system-level performance outcome. ## The public component record names bandwidth, stack and interface figures [source 1](https://news.samsung.com/global/samsung-ships-industry-first-commercial-hbm4-with-ultimate-performance-for-ai-computing) [source 2](https://semiconductor.samsung.com/dram/hbm/hbm4/) Samsung says its HBM4 offers 11.7 Gb/s consistent transfer speed, up to 13 Gb/s capability, and up to 3.3 TB/s per stack. Its public product page describes 2,048 I/O pins, 12-high packaging and 1c DRAM with a 4 nm logic base die. The release gives 24 GB to 36 GB capacity for the 12-layer product and describes a possible 16-layer expansion. These are component-level specifications and manufacturer statements. They say nothing by themselves about a host's memory controller, a customer's package, usable capacity or model-serving throughput. ## Packaging and power claims need the stated comparison boundary [source 1](https://news.samsung.com/global/samsung-ships-industry-first-commercial-hbm4-with-ultimate-performance-for-ai-computing) [source 2](https://semiconductor.samsung.com/dram/hbm/hbm4/) Samsung attributes a 2.7-times single-stack bandwidth increase versus HBM3E and a 40 percent power-efficiency improvement to its low-voltage TSV I/O and power-distribution optimization. It also states thermal-resistance and heat-dissipation comparisons. Those figures belong to Samsung and to its stated predecessor comparison; they are not independent measurements of a complete accelerator. An integrator still has to test its own package, interposer, cooling, voltage delivery and memory workload. High bandwidth can improve a bottleneck only if the rest of the system supplies data and operates within its power and thermal limits. ## Shipment status sits beside a specific 12-high component description [source 1](https://news.samsung.com/global/samsung-ships-industry-first-commercial-hbm4-with-ultimate-performance-for-ai-computing) [source 2](https://semiconductor.samsung.com/dram/hbm/hbm4/) Samsung's February release combines a status statement—mass production and commercial shipment—with a defined component description: 12-layer HBM4 stacks from 24 GB to 36 GB, 11.7 Gb/s consistent speed, capability up to 13 Gb/s and a stated maximum 3.3 TB/s per stack. Its product page adds 2,048 I/O pins, 1c DRAM, a 4 nm logic base die, low-voltage TSV I/O and power-distribution optimization. This connects the shipment announcement to a physical memory design rather than a generic HBM4 label. Samsung also describes a future 16-layer option reaching 48 GB; that is a roadmap statement, distinct from the announced 12-layer commercial product. The release places HBM4E sampling in the second half of 2026 and custom HBM sampling in 2027. Samsung's 12-layer shipment record is separate from those later sample milestones. It attributes the 2,048-pin interface to the higher bandwidth. All efficiency and thermal comparisons remain Samsung claims. ## Sources 1.
