Semiconductor Market Commentary, Thru Project Mascot
TSMC's conservative delay in high-NA adoption will be its downfall as Intel's stitching advances sooner. TSMC's larger-mask alternative requires changing the entire stage and is projected for production by 2033; Intel's stitching is substantially derisked and could be ready for volume production in 2027 at the earliest. TSMC's CoWoS and CoPoS shortcomings add to the concern. x.comÂ
TSMC may lose pricing power as performance gains shift from shrinking transistors to stacking, interconnects and optics, while logic folding could make older processes competitive. Despite strong leading-edge demand, investors may overestimate the profit share its node leadership can retain. Its cautious expansion and past reluctance toward advanced packaging suggest a risk-averse culture that protects returns but could leave it late to disruptive technologies and key customers. x.comÂ
High-NA EUV adoption, supposedly ASML's weak spot, now has all three leading-edge buyers on board, shrinking adoption uncertainty. Intel already runs High-NA in high-volume manufacturing, Samsung takes it for DRAM in 2028, and TSMC just formed a joint initiative with ASML on 12-inch photomasks for High-NA. The ramp stays back-loaded: TSMC won't run it in volume until 2030, and the mask work targets a 2031 pilot line and 2033 production readiness. x.comÂ
TSMC's strong AI demand is straining supply, while solid company fundamentals and attractive semiconductor valuations make an abrupt stop to its advance unlikely. TSMC's Wendell Huang expects 2026-28 capex to be significantly higher than in the previous three years to support customer growth; he says most capex is tied to long-term demand. x.comÂ
Intel's poor EMIB-T packaging yields threaten its plans for next year. Per a confidential source, yields are very poor, and EMIB-T may now slip into the following year. The 14A PDK 0.9 matters more for the long term. Intel remains a very strong long-term bull case because yields should improve, though setbacks can arise along the way; whether to avoid this near-term risk is a personal judgment. x.com x.com x.com x.com x.com x.comÂ
TSMC's AI growth still faces margin pressure from overseas fab expansion and a faster A14 ramp for mobile customers facing 2nm SoC challenges. 3Q gross margin of 66.4% missed expectations, and the 4Q guide is softer at 65-67%; margins are expected to remain largely flat through 2027-28 despite projected 39% revenue growth in 2027. Hold; target nudged to NT$2,999 at 20x 2027 earnings. x.com x.com x.comÂ
Architecture changes could lift TSMC wafer demand. Shifting from 12-high to 8-high lifts volumes; an on-device AI phone upgrade cycle would be enormously bullish, while ASIC gains over Nvidia help because ASICs use more wafers. TSMC is arguably more vital to AI buildout than MAG stocks and a reasonable extended-AI-cycle play at a not-crazy multiple, barring big macro events. Margins may not expand as capex rises; a Terrafab partnership, if it happens, would somewhat ease Intel competition risk. … Show more
TSMC's shifting cost structure is pressuring gross margin despite revenue and EPS beats. TSMC reported Q3 gross margin of 66.4%, down from 67.7% in Q2, and another decline is guided next quarter; Arizona is expected to drag gross margin by 2-4%. TSMC is checking AI data-center progress as it plans wafer capacity, while reiterating long-term AI demand strength. Price hikes may be next, given management's commitment to protect shareholder interests. x.com x.comÂ
Intel is scaling its foundry turnaround with 18A in high-volume production and yields ahead of plan. Q2 revenue rose 25% to $16.1B, with Panther Lake on 18A. 14A risk production is set for the second half of 2027 and high-volume ramps for 2028, and two prospective 14A customers will decide between the second half of 2026 and the first half of 2027. Capex tops $20B this year and rises sharply in 2027. Nvidia invested $5B and is co-developing custom x86 CPUs; the US government holds 9.9%. x.comÂ
TSMC's conversion of 4nm/5nm capacity to 3nm to clear a backlog stretching to 2028 shows 3nm is the bottleneck, and TSMC controls the queue. Broadcom flagged the constraint publicly. The mix shifts toward 3nm premium pricing, with AI accelerator growth guided in the mid-to-high 50s% over five years, so every conversion is margin expansion disguised as logistics. TSMC is trading handset volume for HPC and AI margin, leaving Qualcomm, MediaTek and other non-Apple customers to absorb the squeeze. … Show more
Intel's high valuation is hard to justify while its foundry turnaround remains unproven. At about 59x forward earnings, nearly three times TSMC's 19x, Intel has slower projected revenue growth; its foundry lost $2.09 billion in Q2 2026, while TSMC's Q3 operating margin was 58.7%. A politician's stock purchase alone does not make Intel a buy. x.com x.comÂ
