AMD CEO Lisa Su was expected in Seoul on October 7, 2026, for AMD Gamer Day, with meetings involving Samsung and other Korean companies anticipated but not confirmed in reporting available that day. The companies already have a March 18 memorandum of understanding covering HBM4 and other memory collaboration; it is not evidence of a new binding supply contract or a Samsung foundry award.
What was expected during Su’s South Korea visit?
Aju Press reported on October 6 that Su was due to attend AMD Gamer Day in Seoul on Wednesday, October 7, and that a media Q&A and meetings with Korean AI-chip companies and government officials were expected. Seoul Economic Daily had reported on September 30 that Samsung could be among the companies Su might meet, while companies had not confirmed specific meeting schedules.
As of the reporting available on October 7, a meeting with Samsung’s chip leadership—and any new agreement announced during the visit—had not been confirmed. The distinction matters: an expected executive meeting is not the same as a completed negotiation or a change to AMD’s supply commitments.
What AMD and Samsung had already agreed to discuss
On March 18, 2026, Samsung and AMD announced a memorandum of understanding at Samsung’s Pyeongtaek complex. The announced scope has three distinct tracks:

- Disclaimer: Maximum Speed requires overclocking/PC BIOS adjustments. Maximum speed and performance depend on system components, including motherboard and CPU
- Hand-sorted memory chips ensure high performance with generous overclocking headroom
- VENGEANCE LPX is optimized for wide compatibility with the latest Intel and AMD DDR4 motherboards
- A low-profile height of just 34mm ensures that VENGEANCE LPX even fits in most small-form-factor builds
- A solid aluminum heatspreader efficiently dissipates heat from each module so that they consistently run at high clock speeds
- HBM4 for AMD’s MI455X accelerator: The companies said they would align on primary HBM4 supply for the next-generation accelerator.
- Memory for EPYC and Helios: They described memory solutions for AMD’s sixth-generation EPYC processors, codenamed “Venice,” and DDR5 for the Helios rack-scale platform.
- Possible foundry services: The companies said they would discuss potential Samsung foundry services for future AMD products. The announcement did not establish a foundry manufacturing contract.
The MOU signals broader cooperation, but its public terms do not establish volumes, pricing, delivery schedules, exclusivity or a binding supply award. Those details should not be inferred from the announcement.
Why HBM and memory availability matter to AMD
High-bandwidth memory (HBM) is specialized memory used in AI accelerators, where moving data quickly is important to performance. Samsung’s March announcement describes its HBM4 as using 1c-class DRAM and a 4nm logic base die, with speeds of up to 13 Gbps and maximum bandwidth of 3.3 TB/s. Those are Samsung’s vendor-published specifications, not independent comparative test results.
Rank #2
- Boosts System Performance: 32GB DDR5 RAM laptop memory kit (2x16GB) that operates at 5600MHz, 5200MHz, or 4800MHz to improve multitasking and system responsiveness for smoother performance
- Accelerated gaming performance: Every millisecond gained in fast-paced gameplay counts—power through heavy workloads and benefit from versatile downclocking and higher frame rates
- Optimized DDR5 compatibility: Best for 12th Gen Intel Core and AMD Ryzen 7000 Series processors — Intel XMP 3.0 and AMD EXPO also supported on the same RAM module
- Trusted Micron Quality: Backed by 42 years of memory expertise, this DDR5 RAM is rigorously tested at both component and module levels, ensuring top performance and reliability
- ECC Type = Non-ECC, Form Factor = SODIMM, Pin Count = 262-Pin, PC Speed = PC5-44800, Voltage = 1.1V, Rank And Configuration = 1Rx8
The significance for AMD is not limited to the accelerator itself. The MOU also links memory collaboration to EPYC processors and the Helios platform, so the cooperation spans components used across a data-center system. AMD’s August 4, 2026 second-quarter results release identifies availability of essential components, including memory supply, as a factor that could cause actual results to differ materially from expectations. That is a disclosed business risk, not a statement of AMD’s current inventory or allocation.
How long might the memory crunch last?
Seoul Economic Daily reported that TrendForce forecast the memory shortage could persist through 2027, as AI-server investment grows and suppliers balance capacity between HBM and conventional DRAM. This is a forecast relayed by a news outlet, not a guaranteed shortage timeline. The report does not provide enough detail to establish TrendForce’s underlying methodology or specific supply-demand estimates.
Rank #3
- Disclaimer: Maximum Speed requires overclocking/PC BIOS adjustments. Maximum speed and performance depend on system components, including motherboard and CPU
- AMD EXPO & Intel XMP 3.0 Compatible Only: Dual memory profiles allow you to easily select optimized settings for your platform, whether you’re running an AMD or Intel processor
- Dynamic RGB Lighting: Individually addressable RGB lighting delivers vibrant effects through a sleek, understated panoramic diffuser
- Onboard Voltage Regulation: Onboard voltage regulation for reliable power at high frequencies
- Maximum Bandwidth and Tight Response Times: Optimized for peak performance on the latest AMD and Intel DDR5 motherboards
For readers assessing the business implications, the grounded takeaway is that memory availability is a recognized risk and a reported industry concern. The available reporting does not quantify how much memory AMD can secure, how its supply compares with competitors, or what effect the forecast will have on product shipments or financial results.

The March MOU shows AMD seeking closer coordination with a major memory supplier for a forthcoming accelerator and related data-center products. If the October visit produces a confirmed development, it would need to be evaluated on its actual terms—such as whether it creates a binding supply commitment, adds capacity, or awards foundry work—rather than on the fact of a meeting alone.
Until such terms are announced, the known facts are narrower: AMD and Samsung announced memory and foundry-service discussions in March; Su’s Seoul visit and possible meetings were reported as expected in October; and AMD has disclosed component availability as a risk. None of those facts by itself establishes a new contract, guaranteed supply, or a particular financial outcome.
