Pros & Cons
Pros
- 32GB RAM — the highest of any NPU laptop here, enables 13B Q4 local inference
- 47 TOPS NPU — slightly more than Snapdragon X Elite's 45 TOPS
- 3K OLED 120Hz touch display — best screen in the NPU laptop category
- Thunderbolt 4 — docks, eGPUs, and fast external storage all supported
- Full x64 native performance — no ARM emulation compatibility issues
Cons
- Intel Arc integrated GPU is less efficient than Snapdragon X Elite GPU for AI
- Higher power consumption than ARM-based Snapdragon X Elite — shorter battery life
- Intel NPU ecosystem (OpenVINO) less user-friendly than Qualcomm's for beginners
Who Should NOT Buy This
Honest assessment
- All-day mobile use — battery life is shorter than Snapdragon X Elite laptops
- Users needing ARM-native AI tool support — some Qualcomm-optimized models won't run on Intel NPU
Our Verdict
ASUS Zenbook S14 (2025)
The ASUS Zenbook S14 is the best Intel Copilot+ laptop and the only one in this roundup with 32GB RAM — a meaningful advantage for running 13B models locally. If you need x64 compatibility, a stunning display, and Thunderbolt 4, this beats the Surface Laptop 7 for developer use. Battery life is shorter than Snapdragon-based laptops, but the performance and display quality justify the trade-off for desk-forward workflows.
Frequently Asked Questions
Q1Can the ASUS Zenbook S14 run a 13B LLM locally?
Yes. With 32GB unified memory, the Zenbook S14 loads Llama 2 13B at Q4_K_M (requires ~8GB) entirely in RAM with significant headroom. CPU inference via llama.cpp delivers 3–6 tokens/sec. Intel Arc's iGPU with OpenVINO can accelerate inference on compatible models to 8–15 tokens/sec — slower than dedicated GPU but usable for local chat.
Q2How does Intel's 47 TOPS NPU compare to Qualcomm's 45 TOPS?
Raw TOPS numbers are not directly comparable between Intel and Qualcomm because they measure different operation precisions. In practice, Qualcomm's NPU has broader current software support via QNN (Qualcomm Neural Network SDK). Intel's NPU uses OpenVINO and ONNX Runtime and is improving rapidly. For most Windows AI Studio and Copilot+ features, both perform comparably.
Q3Does Thunderbolt 4 matter for AI on the Zenbook S14?
Yes. Thunderbolt 4 enables connecting a TB4 dock (like the CalDigit TS4 or Anker 777) for multi-monitor setups, and more importantly enables external GPU enclosures via Thunderbolt — though eGPU performance on TB4 is bandwidth-limited compared to native PCIe. TB4 also enables fast external NVMe access for storing large model libraries.
