Intel is set to detail (PDF) the advantages of its 18A manufacturing technology (1.8nm-class) compared to its Intel 3 fabrication process at the upcoming VLSI Symposium 2025. As expected, the new production node will offer substantial benefits across power, performance, and area (PPA) metrics, thus providing tangible advantages both for client and data center products.
Intel claims that its 18A fabrication process delivers 25% more performance at the same voltage (1.1V) and complexity, as well as 36% lower power at the same frequency and voltage of 1.1V for a standard Arm core sub-block compared to the same block fabricated on Intel 3 process technology. At a lower voltage (0.75V), Intel 18A provides 18% higher performance and 38% lower power. In addition, 18A consistently achieves 0.72X area scaling compared to Intel 3.
