Mizuho Securities forecasts industry server CPU shipments to reach 50 million units by 2027, a 40% year-over-year increase, driven by an accelerating CPU-to-GPU ratio on AI servers expected to approach 1:1 by late 2027 or 2028. A critical bottleneck exists in DDR5/LPDDR5 supply, with a projected fulfillment ratio of only 70% over the next 12–18 months, as 2027 demand significantly exceeds projected supply. The total AI ASIC market is projected to grow from 4.1 million units in 2025 to 24.0 million units by 2028, with Google, Amazon, Meta, and Anthropic significantly ramping up custom chip deployments.
AI server demand is driving a structural shift to 1:1 CPU-to-GPU ratios, while DRAM supply remains a critical bottleneck through 2027, impacting server output.
