AI / ML
- 50 TOPS INT8 NPU 5 for local AI inference.
- Combined CPU + iGPU + NPU AI TOPS in the ~180 TOPS range depending on workload.
- Well‑suited for AI assistants, background blur, noise suppression, and local LLMs in optimized frameworks.
- 50 TOPS NPU enables local AI features like Windows Studio Effects and lightweight LLM inference.
- Combined CPU + GPU + NPU acceleration benefits OpenVINO, DirectML and ONNX workflows.
- Not aimed at heavy datacenter‑style training, but strong for client‑side AI PC experiences.
Content Creation
Gaming
- 4‑core Xe3 iGPU is similar to Radeon 840M in early Geekbench Vulkan results.
- Adequate for eSports and older titles at 1080p low/medium.
- Modern AAA titles will require reduced settings and/or resolution scaling.
- Arc B390 iGPU is a major upgrade over earlier Intel mobile iGPUs.
- Suitable for 1080p gaming in many esports and AAA titles at medium–high settings.
- Ray tracing is supported but best used selectively due to iGPU limitations.
- Discrete GPUs still preferred for high‑refresh 1440p+ gaming.

Strengths & Weaknesses
Pros
- 16 hybrid cores with strong single‑thread and multi‑thread performance for a mobile chip.
- Intel 18A process with good performance per watt and configurable 15–80 W TDP range.
- 50 TOPS NPU 5 and ~180 TOPS platform AI for on‑device AI workloads.
- 20 PCIe 5.0/4.0 lanes, more than many thin‑and‑light mobile CPUs.
- LPDDR5X‑8533 and DDR5‑7200 support with up to 128 GB RAM.
- Xe3 iGPU with ray tracing and modern video codecs including AV1 encode/decode.
Cons
- Only 4 Xe3 iGPU cores; not suitable for serious gaming without a discrete GPU.
- No Hyper‑Threading; 16 threads is decent but less than some 8‑core SMT designs in heavily threaded workloads.
- Locked multiplier; no enthusiast overclocking headroom.
- 80 W turbo requires a laptop chassis capable of cooling that power, which may limit sustained performance in thin designs.
- New platform; early‑driver and firmware maturity may still be improving.
Pros
- 16 hybrid cores with strong single‑thread and multi‑thread performance.
- Arc B390 iGPU is a big step up for integrated gaming and content workloads.
- 50 TOPS NPU enables serious AI PC experiences without a discrete GPU.
- Intel 18A and advanced packaging bring good efficiency for the performance level.
- 25–80 W configurable TDP fits a wide range of laptop designs.
Cons
- Confusing X9 vs 9 branding and near‑identical specs to X7 368H make positioning unclear.
- No vPro or embedded support limits use in business and industrial designs.
- iGPU still can’t replace a discrete GPU for high‑refresh 1440p/4K gaming.
- Locked multiplier offers limited overclocking fun.
- Real‑world laptop performance depends heavily on OEM power and thermal tuning.

Lower power and very good efficiency for lighter thin‑and‑light designs where 16 cores are overkill.
Our Verdict on Each
A very capable mobile AI PC processor that balances CPU performance, power efficiency, and on-device AI, but its small 4-core Xe3 iGPU limits serious gaming or heavy GPU compute without a discrete GPU.
Best for: AI‑enhanced business or productivity laptops where you want strong CPU performance, on‑device AI, and good efficiency, but don’t rely heavily on integrated graphics for gaming.
Read the full reviewA very capable high-end mobile SoC that brings strong multi-threaded performance, a potent integrated GPU and serious AI acceleration to thin laptops, though its confusing naming and near-identical specs to the X7 368H make it hard to justify on price alone.
Best for: Premium thin‑and‑light laptops where strong iGPU, AI features and multi‑threaded performance matter more than ultra‑low price or maximum gaming FPS.
