The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 cores provide smooth multitasking for daily laptop use.
Capable in content creation and professional apps, with competitive single-core and solid multi-thread performance for an 8-core mobile CPU in 2021, but newer designs pull ahead in sustained workloads.
Gaming
Handles esports and mid-range gaming well when paired with a decent mobile GPU.
Strong for 1080p gaming at high refresh rates when paired with a midrange or better discrete GPU. Modern 12th/13th-gen Intel and Ryzen 6000/7000 mobile CPUs tend to edge it out in CPU-heavy titles and efficiency.
Virtualization
Can run basic VMs but limited by mobile power constraints.
Good for running several VMs or containers on a laptop, but limited by 8 cores and typical laptop power limits compared to modern HX-series parts.
Efficiency
Good balance of performance and battery life.
Performance-per-watt is decent but not class-leading; AMD’s Ryzen 5000/6000 and Intel’s Alder Lake/Raptor Lake are notably more efficient under many workloads.
Specialized Performance
AI / ML
- Basic CPU inference
- No dedicated AI hardware
- No dedicated NPU; relies on CPU AVX-512 and GNA 2.0 for AI workloads
- Suitable for light local inference and on-device ML, not serious training or large models
- Intel Deep Learning Boost (AVX-512 VNNI) helps some quantized inference tasks
Content Creation
Gaming
- Suitable for budget gaming laptops
- 4 P-cores handle games well
- E-cores manage background tasks
- High single-core turbo (up to 4.9 GHz) benefits CPU-bound games
- Performance highly dependent on laptop cooling and power limits
- Competitive with Ryzen 7 5800H in many games at similar power
- Newer Intel/AMD mobile CPUs often deliver higher FPS at lower power

Our Verdict on Each
A solid entry-level mobile processor bringing hybrid architecture to budget gaming laptops.
Best for: If you are shopping for an entry-level gaming laptop, the Core i5-12450H provides excellent value. It offers the core benefits of Intel's 12th Gen hybrid architecture without the premium price tag. It pairs well with mid-range mobile GPUs like the RTX 3050 or 4050. However, if you plan to do heavy video editing or 3D rendering, you might want to look for a laptop with the i5-12500H or i7-12700H for better multi-core performance. For pure 1080p gaming and school work, this CPU is more than sufficient.
Read the full reviewA fast 8-core mobile CPU in its day, with strong single-thread performance and PCIe 4.0, but now outclassed by 12th/13th-gen Intel and Ryzen 6000/7000 in efficiency and multi-core performance.
Best for: Buying a discounted 2021-era gaming or workstation laptop where the i9-11900H is already installed, and you prioritize GPU and thermals over CPU generation.
