Steam Hardware Survey: Intel CPU Share Drops To Lowest Figure, Nvidia GPUs See Bump, Octa-Core CPUs Hit 30% - Digital Foundry

Intel's share collapse is a structural erosion by AMD's Zen architecture and ARM's ecosystem pull, not quarterly noise. Octa-core penetration crossing 30% signals the consumer market has permanently exited the four-core era. Intel's window of vulnerability during its process-node struggles is being locked in by Ryzen 7000/9000 on pure price-performance grounds. Nvidia's GPU share uptick is driven by DLSS 4's software moat and RTX 50's launch-cycle premium, while AMD's RDNA4 still lags in driver maturity. Technical cascade: octa-core ubiquity accelerates DDR5 adoption and pushes advanced packaging (EMIB, CoWoS-L) from data centers into consumer silicon, creating bidirectional pressure on TSMC (Taiwan, China) and Intel's foundry ambitions. On compliance, US export controls on advanced GPUs have effectively capped Nvidia's China revenue, forcing its growth engine toward AI inference and data-center workloads. 12-24 month outlook: If Intel 18A fails to hit yield targets by H2 2025, its consumer share will breach the 50% psychological floor. Nvidia faces the dual gauntlet of Blackwell ramp and HBM4 supply constraints. Octa-core is no longer a premium tier-it is the new baseline, and that will fundamentally reprice the CPU market and rewrite software optimization assumptions for the next generation.
