The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Excellent multi-threaded performance for video editing, 3D rendering, and heavy multi-tasking; comparable to lower-power desktop CPUs in short bursts.
Strong multi-threaded performance handles creator applications well, though modern alternatives are faster.
Gaming
Provides very high FPS in CPU-heavy titles and high-refresh 1440p gaming when paired with a high-end GPU, but is often GPU-bound at 4K and limited by laptop power/thermal throttling.
Competent for gaming at high refresh rates, but newer CPUs offer better performance and efficiency.
Virtualization
Strong for running several VMs or containers on a laptop, with 32 threads and ample memory support, though sustained loads depend on laptop power limits.
8 cores and 16 threads provide ample resources for running multiple virtual machines.
Efficiency
High performance-per-watt at low loads, but under multi-core turbo it draws significantly more power than typical mobile CPUs, impacting battery life and thermals.
14nm process consumes more power and generates more heat compared to modern 7nm+ mobile processors.
Specialized Performance
AI / ML
- No dedicated NPU; AI workloads run on CPU or iGPU.
- Good CPU-based inference performance for local LLMs and image models thanks to high clock and 32 threads.
- For serious local AI, a dedicated GPU or NPU-based platform is more efficient.
- No dedicated AI acceleration hardware
- Can handle CPU-based inference for small models
- Far surpassed by modern NPUs and AI-focused processors
Content Creation
Gaming
- Very high single-core clocks and strong IPC deliver high FPS in most games.
- Best experienced with a high-end GPU (RTX 4080/4090 class) and good cooling.
- Performance is often GPU-bound at 4K; CPU differences matter more at 1440p/1080p high refresh.
- Power and thermal limits in some laptops can reduce boost clocks under combined CPU+GPU load.
- High single-core clocks benefit game performance
- Capable of driving high-refresh-rate gaming with a discrete GPU
- Integrated UHD 630 is not suitable for modern gaming
- Outperformed by newer mobile CPUs in efficiency and integrated graphics
