"AI War, Round 2: Samsung vs SK, First Public Reveal of 'HBM4' Physical Samples! (ft. Goodbye HBM3E? 🤯)"
Folks! Folks! 🤯 It's finally happened!
The competition for HBM (High Bandwidth Memory), often called the 'rice' or 'oil' of the AI era... You thought HBM3E was the ultimate king, right?
The HBM market is changing at an incredibly rapid pace, day by day.
It feels like only yesterday that we were intensely competing to supply HBM3E to NVIDIA, and now it's already HBM4.

HBM4 is the 6th generation product succeeding HBM3E, set to begin mass production in late 2025 and be integrated into AI accelerators as the 'next-generation heart' from 2026.
But today, Samsung Electronics and SK Hynix, as if by prior agreement, unveiled 'physical samples' of this HBM4. OMG.
(The fact that they unveiled something that was only seen in blueprints suggests their confidence: "We have this level of technology! Get in line!")
Their strategies are completely different, making it even more exciting. I'll summarize everything for you!
1. "Forget HBM3E": What's Different About HBM4?
"Aren't 3E and 4 pretty much the same?" you might ask, but HBM4 represents a complete technological leap, a 'generational change'.
- Higher Capacity (16-Stack): It goes beyond the existing 12-stack to build a 16-stack (Hi-Stack), maximizing capacity.
- New Technology (Hybrid Bonding): It shifts from bonding chips with 'adhesive' (TC-NCF) to directly connecting them with 'copper' (Hybrid Bonding), dramatically boosting speed and efficiency.
- Wider Road (2048-bit): It doubles the data path (I/O) from 1024-bit to 2048-bit, drastically increasing bandwidth.
In short, it's a core component that enables AI to run "faster, with more data, and more intelligently."
2. SK Hynix: "Existing No. 1, We're First with 16 Stacks!" (feat. Hybrid Bonding)
SK Hynix, currently the No. 1 in the HBM market, is focused on 'defending its position'. 👑
The HBM4 physical sample unveiled by SK Hynix prominently features 'Hybrid Bonding' technology. While HBM3E used the traditional TC-NCF technology, to stably stack 16 layers, Hybrid Bonding is now essential.
SK Hynix is known to have already sent 16-stack samples to key customers like NVIDIA. This demonstrates their confidence, effectively saying, "We are the original HBM experts! We are the best at 16-stack integration too!"
3. Samsung Electronics: "We're the 'Thinking' HBM!" (feat. Logic Die)
In contrast, the 'challenger' Samsung Electronics has brought out a 'game-changer' card to completely disrupt the playing field.
Q. What's different about Samsung's HBM4? 🧐
A. Samsung has introduced a 'Custom HBM' strategy.
If traditional HBM only served as a simple 'storage unit', Samsung's HBM4 integrates a 'Logic Die' inside the HBM.
What does this mean?
It means that "memory can perform 'computation (thinking)' by itself." (PIM: Processing-in-Memory)
Instead of AI having to go all the way to the brain (GPU) to fetch necessary data, some processing can be done directly within the storage (HBM), leading to incredibly faster speeds! ⚡
4. "AI War, Round 2": Who Will Be the Victor?
In summary, the HBM4 war looks like this:
- SK Hynix: Aims for 'stability' and 'yield' through ultra-high 16-stack integration using 'Hybrid Bonding'!
- Samsung Electronics: Aims to be a 'game changer' in 'performance' and 'efficiency' with 'PIM' technology integrating 'Logic Die'!
It feels like the HBM3E competition was just yesterday... but the 'HBM4 physical sample war' to claim the throne in 2026 has already begun.
Between 'Stable SK' and 'Innovative Samsung', who do you think will be the winner of this HBM4 battle? 🤔
