Reported by TechPowerUp on November 5, 2026. Summarized and analyzed by XAIPART Editorial.
What happened
Samsung has reportedly reserved the full planned production capacity of its second Taylor, Texas, fabrication facility, with AMD accounting for most of that allocation.S1 The report also identifies NVIDIA as a prospective customer for 2 nm HBM base dies produced at the site.S1 Samsung declined to comment because it could not confirm customer-related details.S1
The planned products would be HBM base dies rather than AMD processors or graphics processors. A base die provides the logic layer beneath an HBM stack, and Samsung intends to combine dies fabricated in Texas with DRAM produced in South Korea before shipping the completed memory products.S1
| Metric | Reported value | Source |
| Planned Taylor Fab 2 HBM base-die process | 2 nm | S1 |
| Base-die process used by current HBM4 and sampled HBM4E | 4 nm | S1 |
Samsung's existing HBM4 and sampled HBM4E use 4 nm base dies, while the proposed 2 nm process appears intended for subsequent HBM generations.S1 The report connects the allocation to a March memorandum of understanding that named Samsung as the primary HBM4 supplier for AMD's Instinct MI455X and to Lisa Su's October visit to Samsung, during which foundry orders were reportedly discussed in relation to AMD's HBM requirements.S1
Background timeline
- March - A memorandum of understanding named Samsung as the primary HBM4 supplier for AMD's Instinct MI455X.S1
- October - AMD CEO Lisa Su visited Samsung, where foundry orders were reportedly discussed in return for HBM supply.S1
- - TechPowerUp reported that Taylor Fab 2's planned output was fully booked, mostly by AMD.S1
XAIPART take
Technical impact
XAIPART analysis: Buyers should distinguish the 2 nm logic base die from the finished HBM stack and from AMD CPUs or GPUs. Qualification plans therefore need to cover the base die, the South Korean DRAM layers, assembly, test and the finished memory interface rather than treating the reported allocation as a processor-capacity commitment.
XAIPART analysis: The move from a 4 nm to a 2 nm base-die process may support later HBM generations, but the report does not identify a shipment schedule or confirm which future products will enter production.
Market impact
XAIPART analysis: A reported full booking of Taylor Fab 2 could reduce available Samsung capacity for additional advanced HBM base-die customers, particularly if AMD retains the majority allocation. That could make alternative foundry and packaging routes strategically relevant to buyers managing multi-generation accelerator roadmaps.
XAIPART analysis: The source discloses no wafer starts, units, pricing or allocation lead times, so procurement teams should avoid translating the report directly into a cost or supply-duration assumption.
Action
XAIPART analysis: Request written confirmation of customer qualification, available HBM4 and HBM4E volumes, and the expected transition window for 2 nm base dies. Suppliers should also provide a qualified alternative-base-die strategy in case Samsung reallocates capacity or adjusts the production schedule.
XAIPART analysis: Compare the proposed roadmap against current 4 nm base-die offerings, and check whether packaging, thermal, power and validation schedules can accommodate a later-generation HBM change without creating an avoidable redesign.
XAIPART Forecast
XAIPART expects AMD to retain more than 50% of Taylor Fab 2's allocated 2 nm HBM base-die output within 12 months of this report. If AMD's share falls below 50% while the site remains fully booked, this forecast is wrong. XAIPART analysis
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The capacity report is based on unnamed industry sources, Samsung did not confirm customer details, and production volume, pricing and lead time were not disclosed.
Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
