The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Excels in multi-threaded productivity applications due to the 12-thread hybrid design.
10 cores and 20MB cache make it great for heavy productivity.
Gaming
Provides high frame rates in modern titles when paired with a mid-range to high-end discrete GPU.
Handles high-refresh-rate gaming; not a bottleneck for RTX 4060/4070.
Virtualization
Capable of running local virtual machines efficiently, though core count limits heavy parallel VMs.
16 threads and 20 PCIe lanes allow for complex local setups.
Efficiency
Efficiency is lower compared to P and U series due to the 55W base power and desktop lineage.
55W base and 157W boost consume significant power and generate heat.
Specialized Performance
AI / ML
- Can handle basic local AI inference.
- Lacks a dedicated NPU found in newer generations.
- No NPU; relies on discrete GPU for AI acceleration.
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.
- Unlocked for tuning.
- 20 PCIe lanes prevent bottlenecks with discrete GPUs.
