AMD Zen 7 Details Leak – “Grimlock” to use TSMC A14 node - OC3D

Recent reports from the Taiwan Commercial Times indicate that AMD plans to use TSMC's A14 (1.4nm) process node for its upcoming Zen 7 processors, codenamed 'Grimlock', with trial production expected i... Read original →

AMD’s leapfrog to TSMC’s A14 (1.4nm) node—bypassing N2 variants—is less about Moore’s Law and more a strategic bet on co-optimizing 3D V-Cache, FOPLP packaging, and core microarchitecture. This move pressures EDA vendors and IP houses to accelerate support for atomic-layer lithography and thermal-aware floorplanning. Geopolitically, reliance on A14 capacity in Taiwan, China heightens exposure to U.S.-China tech decoupling risks and CHIPS Act-driven reshoring costs. Intel will likely fast-track its 18A+ node and Foveros Direct stacking to counter Zen 7’s 224MB L3 cache and 25% IPC gain, while NVIDIA may double down on Grace-Blackwell tight integration for AI datacenters. Within 18 months, expanded L2 caches and AI-specific ISAs will shift from differentiators to baseline requirements in the x86 vs. RISC-V performance war.
