For 18 months Samsung was the third HBM vendor on paper only. NVIDIA's quiet May qualification changes everything — including SK Hynix's pricing power and Micron's growth ceiling.
The bottleneck no longer measured in GPUs but in CoWoS slots. How TSMC quietly became the gatekeeper of the entire frontier-AI roadmap — and what the 2027 packaging map looks like.
Wafer-scale inference has spent four years as a press release. With WSE-4 in our hands, the latency-vs-cost economics finally pencil out for a specific, narrow class of workloads.
Samsung's HBM3E yield rates climbed faster than expected in early 2026. We look at what changed in Samsung's production process, the NVIDIA qualification milestone, and whether the third-vendor story is finally real.
Micron's HBM3E sold out through 2027 and the HBM4 sample timeline is closing the gap with SK Hynix. What this means for supply diversification and 2026 pricing dynamics.
vLLM's paged attention paper changed inference economics overnight. Two years of production data later, here's what actually happened to the KV-cache problem — and what's still unsolved.
Inference vendors are racing from FP8 to INT4 as the next lever on compute efficiency. We map the roadmap across frameworks, the accuracy tradeoffs that actually matter in production, and which memory vendors benefit most.
High-Bandwidth Memory isn't "fast DRAM." It's a wholly different manufacturing problem. We go through the stack, the through-silicon vias, and the packaging step that ties it all to the GPU.
JEDEC ratified the standard. NVIDIA's customer requirements then re-opened it. We walk through the spec deltas, the supply implications, and which vendor benefits most.
