SK Hynix HBM4: First Quarter Insights and Applications in Medical Imaging Market
SK Hynix HBM4: From Sample Release to Mass Production Prospects
Since SK Hynix released and demonstrated its HBM4 samples, industry demand for high-bandwidth memory in AI and medical imaging has rapidly increased. SK Hynix disclosed the delivery of 12-layer HBM4 samples in 2025, marking the entry of SK Hynix HBM4 into the customer verification phase, providing higher-bandwidth memory support for subsequent computing platforms in medical imaging, CT/MRI/ultrasound.
SK Hynix HBM4 Release Timeline and Growth Trajectory
SK Hynix HBM4's key milestones include sample delivery and customer testing (from the first half of 2025 to date). Currently, it's in the customer validation and limited-volume supply phase. Based on the manufacturer's roadmap disclosures at FMS and industry conferences, SK Hynix HBM4 commercial mass production is expected to proceed simultaneously with AI accelerator cards and next-generation GPU platforms (medical imaging manufacturers typically complete full-device validation 6–12 months in advance).
Main Application Scenarios of SK Hynix HBM4 in the Medical Field
• Medical Imaging Acceleration: Deep learning reconstruction and super-resolution processing in CT/MRI/interventional imaging rely on high-bandwidth memory. SK Hynix HBM4 can significantly reduce reconstruction time.
• Real-time Ultrasound and Surgical Navigation: In edge AI algorithms for surgical navigation, SK Hynix HBM4 improves model loading and concurrent inference capabilities.
• Medical Imaging Cloud Training and Inference: Hospitals and cloud-based imaging platforms use high-bandwidth memory to accelerate model training and inference cycles. SK Hynix's HBM4 provides bandwidth support for large models. The Edge/AI solutions showcased by Intel and several medical imaging vendors in 2025 also clearly emphasized the synergy between high-performance processors and high-speed memory.
SK Hynix HBM4 Early Sales and Market Feedback
• Sales Volume: As of the second half of 2025, SK Hynix's HBM4 is in the sampling/small batch supply stage, and public sales data is limited. However, feedback from industry channels and foundry partners indicates a significant increase in trial and certification orders for SK Hynix's HBM4, particularly for medical imaging and AI edge server customers. Related industry reports also highlight SK Hynix's milestone in HBM generational upgrades, garnering attention from the capital market and customers.
