AMD MI450 Roadmap and the Hyperscaler Bake-off
AMD just dropped MI450 — the bake-off with Nvidia’s Blackwell-Ultra is live.
Schedule: Q4 2026 sample, Q1 2027 ramp, 384GB HBM4, chiplet design splitting compute and memory dies on a CoWoS-S substrate. AMD claims parity-or-better aggregate FLOPS at materially lower power.
Why hyperscalers care
Microsoft, Meta, Oracle openly diversifying away from Nvidia-only stacks. ROCm ecosystem maturity is finally meeting the silicon ambition.
The CFL read: AMD has earned a real seat. Whether it pulls share depends on supply chain. CoWoS capacity is still the binding constraint.
