CPU Comparison
Intel Core Ultra 5 125H vs Intel Core Ultra 9 185H
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 125H is a highly versatile mobile processor introduced in December 2023 as part of the inaugural Meteor Lake lineup. Designed to bridge the gap between performance and efficiency, it features a unique 14-core hybrid architecture. This includes 4 P-cores, 8 E-cores, and 2 Low-Power E-cores (LP E-cores), totaling 18 processing threads. Operating at a base frequency of 3.6 GHz and boosting up to 4.5 GHz, it provides robust computational power for thin-and-light laptops. The processor is built on Intel's 7nm process for the compute tile, supplemented by TSMC N6 and N5 nodes for the SOC and graphics tiles. It introduces an integrated NPU delivering 11 TOPS, marking Intel’s first major step into AI acceleration on mobile platforms. With a 28W base TDP and a maximum power draw of 115W, the 125H balances aggressive burst performance with the thermal constraints of premium ultraportables, making it a well-rounded chip for creators and professionals.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi-core performance handles heavy office workloads and compilation effortlessly.
16 cores and 22 threads handle heavy creative workloads easily.
Gaming
Performs well in esports and older AAA titles at 1080p medium settings thanks to the 96 EU graphics.
Arc 128EU is a huge upgrade over older Intel iGPUs, capable of 1080p medium gaming.
Virtualization
18 threads provide ample resources for running development VMs and containers.
Good for running VMs on a laptop, though limited by thermal constraints.
Efficiency
Good efficiency for a 28W part, though not as battery-friendly as Lunar Lake.
Meteor Lake is efficient, but the 185H is a 45W part and can get warm.
Specialized Performance
AI / ML
- 11 TOPS NPU is suitable for background AI tasks
- Does not meet Copilot+ PC 40 TOPS requirement
- AI workloads are shared between CPU, GPU, and NPU
- 11 TOPS NPU is sufficient for background blur and noise cancellation
- Does not meet Copilot+ PC standards (requires 40+ TOPS)
- AI tasks often fall back to CPU/GPU for maximum performance
Content Creation
Gaming
- 96 EU Arc graphics are a massive step up from older Iris Xe
- Supports hardware ray tracing
- Can play most modern games at 1080p low/medium settings
- Arc 128EU graphics allow decent 1080p gaming without a dGPU
- Supports hardware ray tracing (though limited)
- Performance depends heavily on laptop cooling solution
