Intel shares stumble as Nvidia pauses chip production tests

Intel’s share price has taken a hit on Wall Street following reports that tech giant Nvidia has temporarily halted trials for the chipmaker’s manufacturing process. According to Bloomberg, the suspension of tests regarding Intel’s advanced production capabilities caused the stock to dip by nearly 2 per cent. While neither company has officially commented on the specifics, Reuters suggests that Nvidia has opted not to proceed to the next stage of testing the so-called 18A process for now. A spokesperson for Intel did, however, insist that their 18A manufacturing technologies are “progressing well”.

The push for domestic dominance

This development comes at a sensitive time for Intel, as the 18A process represents the cornerstone of its strategy to reclaim leadership in semiconductor manufacturing within the United States. Only recently, the firm inaugurated its new Fab 52 facility in Ocotillo, Arizona, the first plant designated for mass production using this specific technology. Described by the company as the most advanced manufacturing capability developed on American soil, the initiative is crucial to Intel’s efforts to rival Taiwan Semiconductor Manufacturing (TSMC), the current global heavyweight in chip production.

Innovations under the bonnet

The 18A process introduces two pivotal innovations designed to handle the massive data volumes demanded by modern industry. Firstly, it utilises new ‘gate-all-around’ technology for transistors—the microscopic switches that power the chips. This allows for far more precise control over power flow, resulting in greater efficiency and reduced energy consumption. Secondly, the manufacturing process itself has been overhauled to assemble chips with a higher transistor density more effectively. With these technical leaps, Intel aims to solidify its position as a key player in the global market while reinforcing domestic production capacity.

Beyond the current hurdles

Despite the reported setbacks with Nvidia, Intel Foundry Services (IFS) has been keen to demonstrate its longer-term architectural vision. In a move that has arguably gone under the radar, the company recently showcased a disruptive approach to future computing on social media platform X. Rather than announcing a specific product with set release dates, Intel revealed a roadmap for scaling CPU and accelerator compute power when a single die can no longer be expanded. The presentation offered a glimpse into a future involving specific technologies such as the 18A-PT Compute Base Die, HBM5 modules, and advanced 3D stacking.

A shift in architectural philosophy

The core of this new discourse revolves around breaking the physical limits of current lithography. Intel is proposing a staggering scalability of more than 12 times the current reticle limit. The message is clear: size is no longer a lithographic problem, but an integration challenge. By combining tiles, memory, and high-speed interconnects, the manufacturing process becomes akin to a set of ‘LEGO bricks for architects’, where the final product is built through modularity rather than being constrained by the physical boundaries of a single silicon wafer.

The battle for the future

This modular approach signals where the sector is heading: wafer-level scalability that defies traditional imagination. While TSMC has briefly touched upon similar concepts involving ‘System-on-Wafer’ designs, Intel appears to be positioning itself ahead of the curve with this complex integration system. As the industry pivots towards these highly complex, tiled systems, Intel is betting that its ability to master this limitless design horizon will ultimately secure its standing against its Taiwanese competitors, regardless of short-term fluctuations on the stock market.
