Intel's 18A process is by far one of the most anticipated ones in the industry, and Team Blue ha shown intentions to take leadership status.
Intel's 18A Process To Be The Foundry's Most Capable Node To-Date, Offering Impressive Improvements Over Predecessors
Intel's divisions are generally pretty underperforming for now, but when you look into the future, it seems like the IFS can potentially turn things around for the company. Under Pat Gelsinger, we saw the foundry division getting much more priority, and this resulted in Intel ultimately pursuing vertical integration of the supply chain to some extent. While things didn't turn out right in the past, the future seems bright, as Intel's 18A process is right around the corner. The process was "flaunted' at the VLSI Symposium 2025, and Team Blue disclosed impressive gains, which we'll discuss ahead.
Some Technical Highlights 2025 VLSI

It was revealed at the start that Intel's 18A process managed to achieve over 30% density scaling relative to Intel 3 thanks to the integration of technologies like PowerVia and BSPDN. In a PPA comparison, Intel 18A manages to deliver 25% faster speed and a 36% reduction in power consumption at 1.1V on a standard Arm core sub-block. Apart from this, Intel 18A achieves better area utilization than Intel 3, which means that the process can achieve better area efficiency and potential for higher density designs.
Interestingly, there's also a "voltage droop" map attached, which depicts the stability of the node under high-performance conditions, and, thanks to 18A's PowerVia technology, the process manages to provide a more stable power delivery. To back up the 18A's competence, the document also attaches a cell library comparison, which shows that with backside power delivery, Team Blue has managed tighter cell packing and improved area efficiency, simply because more space is freed up in the frontside routing.
So, when you look at it, Intel's 18A process is the foundry's most capable node to date, and with improving yield rates, we are indeed hoping for a decisive outcome. When stacked up against industry counterparts, the 18A process matches SRAM density with TSMC's N2 process, which means that the firm has managed to level the competition with the Taiwan giant in terms of node superiority.
We are expected to see 18A in action starting with Panther Lake SoCs and Xeon "Clearwater Forest" CPUs. In terms of the integration of processes in external products, we could see them arrive as soon as 2026, given that Intel manages to deliver on yield rates and mass production.
