The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Excels in multi-threaded productivity applications due to the 12-thread hybrid design.
The 8 E-cores significantly reduce render times in Premiere and Blender.
Gaming
Provides high frame rates in modern titles when paired with a mid-range to high-end discrete GPU.
Excellent frame rates in modern titles, rarely bottlenecking current mobile GPUs.
Virtualization
Capable of running local virtual machines efficiently, though core count limits heavy parallel VMs.
20 threads provide ample resources for running multiple VMs locally.
Efficiency
Efficiency is lower compared to P and U series due to the 55W base power and desktop lineage.
Can draw up to 115W under load, requiring robust laptop cooling.
Specialized Performance
AI / ML
- Can handle basic local AI inference.
- Lacks a dedicated NPU found in newer generations.
- Iris Xe provides some AI acceleration
- Capable of running local LLMs at acceptable speeds for a mobile chip
Content Creation
Gaming
- High boost clocks ensure strong single-core gaming performance.
- Requires a dedicated GPU as the UHD 710 iGPU is only for display output.
- PCIe 5.0 ensures no bottleneck for latest generation graphics cards.
- Won't bottleneck RTX 3070/3080 mobile GPUs
- High average FPS in CPU-heavy titles like CS:GO
- Depends heavily on laptop thermal design
