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.

Seemingly solid preliminary improvements verses Intel 3. But we need to see benchmarks and tests for real-world products with Intel 18A.
