Clusters
The HPC and AI systems market is undergoing its most significant architectural transition in three decades. GPU-accelerated clusters now represent 72% of new procurement — up from 61% in 2024 — as hyperscalers, sovereign governments, and enterprises converge on AI-primary infrastructure. Big-5 hyperscaler AI infrastructure commitments exceed $690B for 2026 alone, and four exascale systems are now operational globally, including Europe's first with Germany's JUPITER Booster. Over 50 sovereign nations have active AI compute programs, with $62B committed in 2025 alone and trending toward $100B+ annually by 2027.

Ethernet Overtakes InfiniBand; Blackwell Volume & Rubin on Horizon: NVIDIA GB200 NVL72 is now in volume production and AMD MI350 has shipped. Ethernet (RoCE 800G) has surpassed InfiniBand as the dominant AI scale-out fabric in 2025, with Ethernet holding 38% share vs. InfiniBand at 28%. NVIDIA Rubin (336B transistors, 50 PFLOPS inference, HBM4) targets late-2026 availability. DOE's Solstice system — targeting 100,000+ Blackwell GPUs and 2,000 EFlop/s — exemplifies the scale now being commissioned. FLOP:byte ratios have grown from ~3:1 (A100) to ~15:1 (B200), making memory bandwidth the defining constraint of the current generation.
