CPU Comparison
Intel Core i7-11800H vs Intel Core Ultra 7 356H
A side-by-side comparison of specs, performance and value. The Intel Core i7-11800H is an 8-core, 16-thread high-performance mobile processor built on the 10nm SuperFin process, designed for heavy-duty gaming laptops and mobile workstations.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Blazes through heavy multi-threaded applications like Premiere Pro and Blender.
16 hybrid cores and strong multi-core PassMark (≈34k) deliver snappy application responsiveness and good throughput in office, development, and light creative workloads.
Gaming
Consistently high frame rates in modern titles, limited only by the discrete GPU.
The 4-core Xe3 iGPU is noticeably faster than older UHD/Iris Xe but not in the same league as the 12-core Arc B-series iGPUs or modern discrete mobile GPUs. Expect playable 1080p low/medium in e-sports titles, but not smooth 1080p ultra in modern AAA games.
Virtualization
16 threads make it highly capable for local VMs and containerized development.
Capable for light VM usage, but 16 threads and 96 GB max memory are more than sufficient for most client-side virtualization scenarios.
Efficiency
Consumes more power than newer 12th Gen Alder Lake parts under load.
At 25 W base, the 356H is efficient for its performance level; NanoReview rates power efficiency around 83/100, reflecting good performance per watt in typical laptop workloads.
Specialized Performance
AI / ML
- Capable of running medium-sized local AI models
- AVX-512 and DL Boost accelerate CPU-based inference
- NPU 5 up to 50 TOPS INT8 aligns with Intel’s Copilot+ PC requirements
- Good for local AI assistants, background blur, noise cancellation, and light on-device inference
- Not aimed at large-scale model training, but very capable for client AI workloads
Content Creation
Gaming
- Massive 24MB L3 cache boosts game performance significantly
- Handles CPU-bound titles like Microsoft Flight Simulator well
- Pairs perfectly with RTX 3060 and 3070 mobile GPUs
- 4-core Xe3 iGPU is a solid step over 11th/12th-gen UHD but below Arc B390/B370
- Suitable for 1080p low/medium in e-sports and older titles
- For serious gaming, pair with a discrete GPU or choose a Panther Lake SKU with more Xe cores
