NVDA<\/a> tumbled nearly 1% on Wednesday after reports surfaced that the AI chipmaker has paused testing of Intel\u2019s ambitious 18A manufacturing process.<\/p>\nThe move marks a significant setback for Intel\u2019s foundry revival strategy and reinforces questions about whether the chip giant can compete with Taiwan Semiconductor Manufacturing Company (TSMC).<\/p>\n
Both Nvidia and Broadcom had been evaluating Intel\u2019s 18A node over recent months, but the tests have stalled as performance and yield targets fell short of expectations.\u200b<\/p>\n
What the 18A pause means for Nvidia\u2019s supply chain<\/p>\n
Intel\u2019s 18A process promised significant improvements over its previous generation: 30% higher transistor density, 25% faster performance at the same voltage, and up to 36% lower power consumption for equivalent throughput.<\/p>\n
These specs matter because every watt saved translates to lower data center cooling bills, and every percentage point of density improvement means more AI compute per chip die.<\/p>\n
Broadcom and Nvidia spent months running qualification tests, essentially manufacturing small batches of experimental chips to see how the new process would perform in the real world.\u200b<\/p>\n
The pause signals that those prototype runs didn\u2019t deliver the goods.<\/p>\n
When chip designers pull back from testing, it rarely means outright rejection.<\/p>\n
Instead, it reflects either yield problems, performance shortfalls, or architectural mismatches that require more development time.<\/p>\n
Broadcom had already flagged concerns, reportedly telling Intel engineers that 18A was \u201cnot currently viable for high-volume production\u201d back in September.<\/p>\n
Nvidia\u2019s pause suggests similar issues remain unresolved.<\/p>\n
For Nvidia, this is especially notable because the company operates on razor-thin timelines; new AI accelerators must launch on schedule or risk losing market share to competitors.<\/p>\n
Sticking with proven TSMC capacity is the safer play.\u200b<\/p>\n
Intel emphasized that 18A remains \u201con track,\u201d but the reality is blunt: a pause from Nvidia, the world\u2019s most influential chip customer, reads as a vote of no confidence.<\/p>\n
Competing against a foundry that already has 72% market share and a 41% revenue surge in Q3 2025 requires flawless execution.<\/p>\n
Intel has already pushed back the 18A timeline twice, first to 2026, then to mid-2026 due to IP qualification delays, and customer hesitation only compounds the delays.\u200b<\/p>\n
Nvidia stock: Does this reshape the AI foundry map?<\/p>\n
This development actually reinforces TSMC\u2019s near-total dominance of advanced chip manufacturing.<\/p>\n
The Taiwanese foundry controls nearly three-quarters of the market and is shipping the 3nm process at scale while maintaining 90% yields.<\/p>\n
Samsung, Intel\u2019s closest competitor, remains stuck with yield challenges of its own, even as it pushes its 2nm GAA (Gate-All-Around) technology.<\/p>\n
For Nvidia and Broadcom, the path of least resistance is clear: keep working with TSMC.\u200b<\/p>\n
The Nvidia partnership announced in September 2025, which included a $5 billion investment by Nvidia, was supposed to be that breakthrough moment.<\/p>\n
But the deal carefully avoided any manufacturing commitments. Nvidia CEO Jensen Huang explicitly stated the company would continue relying on TSMC. The 18A pause confirms that reality.\u200b<\/p>\n
For markets, uncertainty carries a heavier tax than bad news.<\/p>\n
Intel shares fell 2-3% early Wednesday on the report. Nvidia, too, witnessed some correction, a sign that traders have already priced in the company\u2019s dependence on TSMC.<\/p>\n
Analysts like Angelo Zino from CFRA have warned that Intel\u2019s foundry business will \u201ccontinue to bleed cash at least through 2027,\u201d while Samsung and TSMC will capture the lion\u2019s share of AI chip production capacity.https:\/\/www.gurufocus.com\/news\/4086584\/intc-intel-stock-falls-after-nvidia-backs-out-of-18a-chip-deal\u200b<\/p>\n","protected":false},"excerpt":{"rendered":"Nvidia stock NVDA tumbled nearly 1% on Wednesday after reports surfaced that the AI chipmaker has paused testing…\n","protected":false},"author":2,"featured_media":82783,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[345,343,344,85,46,125],"class_list":{"0":"post-202121","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-artificial-intelligence","8":"tag-ai","9":"tag-artificial-intelligence","10":"tag-artificialintelligence","11":"tag-il","12":"tag-israel","13":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/202121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=202121"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/202121\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/82783"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=202121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=202121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=202121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
