Process Node Comparison
Process nodes are confusingly named—a "3nm" chip doesn't have 3nm features. Here's how they actually compare:
| Generation | TSMC | Intel | Samsung |
|---|---|---|---|
| ~7nm class | N7 (2018) | Intel 7 (2021) | 7LPP (2018) |
| ~5nm class | N5 (2020) | Intel 4 (2023) | 5LPE (2020) |
| ~3nm class | N3E (2023) | Intel 3 (2024) | SF3E (2024) |
| ~2nm class | N2 (2025) | Intel 20A (2025) | SF2 (2025) |
| ~1.4nm class | A14 (2027) | Intel 14A (2027) | SF1.4 (2027) |
Technology Deep Dive
TSMC: The Undisputed Leader
TSMC dominates because of:
- Yield excellence - Consistently highest yields on new nodes
- Pure-play foundry - Doesn't compete with customers
- Ecosystem - Best design tools, IP, and PDKs
- Customer trust - Apple, NVIDIA, AMD all exclusive
TSMC N3 Performance
- Transistor density: 290M/mm²
- 15% speed improvement vs N5
- 30% power reduction vs N5
- Used in: Apple A17 Pro, M3, NVIDIA Blackwell
Samsung: First to GAA
Samsung was first to adopt Gate-All-Around (GAA) transistors with 3nm in 2022. But yield issues hurt customer confidence:
- GAA leadership - 2 years ahead of TSMC on GAA
- Yield problems - Lower yields than TSMC
- Customer defections - Lost Qualcomm flagship chips to TSMC
- Memory expertise - #1 in DRAM and NAND
Intel: The Comeback Story
Intel fell behind in 2015-2020 but is executing an ambitious turnaround under CEO Pat Gelsinger:
- Intel Foundry Services (IFS) - Now taking external customers
- First High-NA EUV - Received before TSMC/Samsung
- US fabs - $20B Ohio plant, Arizona expansion
- 5 nodes in 4 years - Aggressive roadmap execution
Intel 18A (2025)
- First use of RibbonFET (Intel's GAA)
- First use of PowerVia (backside power delivery)
- If successful, could match TSMC N2
Capacity & Geography
| Foundry | Monthly Wafer Capacity | Key Locations |
|---|---|---|
| TSMC | ~2M wafers (all nodes) | Taiwan (90%), USA (Arizona), Japan, Germany |
| Samsung | ~800K wafers | South Korea, USA (Texas) |
| Intel | ~400K wafers | USA (Oregon, Arizona, Ohio), Ireland, Israel |
Customer Landscape
Who Uses What?
| Customer | Primary Foundry | Products |
|---|---|---|
| Apple | TSMC (exclusive) | A-series, M-series chips |
| NVIDIA | TSMC | H100, Blackwell GPUs |
| AMD | TSMC | Ryzen, EPYC, Radeon |
| Qualcomm | TSMC (flagship), Samsung | Snapdragon |
| Samsung | Tensor chips | |
| Microsoft | Intel, TSMC | Custom chips, Surface |
The 2nm Race
All three are racing to 2nm production in 2025:
TSMC N2
- Risk production: H2 2025
- Volume: 2026
- GAA nanosheet transistors
- Backside power optional
- Customers: Apple, AMD
Intel 18A
- Risk production: H2 2025
- Volume: 2026
- RibbonFET (GAA)
- PowerVia (backside power)
- Customers: Intel + IFS
Samsung SF2
- Risk production: 2025
- Volume: 2026
- 2nd gen GAA
- Backside power delivery
- Customers: TBD
Geopolitical Risks
The concentration of advanced manufacturing in Taiwan is a major concern:
- Taiwan risk - 90% of advanced chips come from one island
- US CHIPS Act - $52B to build US fabs (TSMC, Intel, Samsung)
- EU Chips Act - €43B for European semiconductor capacity
- China restrictions - No EUV exports, limited DUV
Verdict: Who Wins?
The Bottom Line
- TSMC - Clear leader today. Best yields, most customers, proven execution.
- Intel - Most ambitious roadmap. If 18A succeeds, back in the game by 2026.
- Samsung - Technology capable but yield/customer challenges persist.
For 2025-2026, TSMC remains the safe choice. Intel is the wildcard that could disrupt—or disappoint.
