- 50 TOPS NPU plus 122 TOPS from Arc B390 GPU and CPU DL Boost provide substantial on‑device AI compute.
- Suitable for local LLM inference, image generation, and Windows Studio Effects.
- Intel’s OpenVINO, DirectML and WindowsML are supported on CPU, GPU and NPU.
Content Creation
Gaming
- Arc B390 with 12 Xe3 cores is a major step up from Arc 140V/Xe2 iGPUs.
- Fine for 1080p medium/high in many esports and AAA titles with upscaling.
- Still not a match for a dedicated RTX 4050/4060 laptop GPU at higher settings.
- Arc B390 iGPU with 12 Xe3 cores delivers integrated graphics performance between a mobile GTX 1660 Ti and RTX 3050 in many synthetic tests.
- XeSS and frame generation are critical for high‑refresh 1080p gaming in newer AAA titles.
- Real‑world results vary with laptop TDP, memory speed, and driver maturity.
- Cyberpunk 2077 at 1200p High with XeSS can reach ~58 fps on some configurations.
- F1 2024 with XeSS 2.0 + frame gen can jump from ~34 fps to over 100 fps at 1200p in some tests.

Strengths & Weaknesses
Pros
- 16 hybrid cores with strong multi‑thread performance for mobile
- Arc B390 iGPU is a huge generational leap over older Intel iGPUs
- 50 TOPS NPU enables serious local AI workloads
- Intel 18A brings improved efficiency and performance over Arrow Lake
- Supports LPDDR5X‑9600 and up to 96 GB memory
- Good balance of performance and power for thin designs
Cons
- Only 12 PCIe lanes from the CPU, limiting multi‑GPU / heavy NVMe configs
- Locked multiplier limits enthusiast tuning
- Not intended for desktop‑class sustained workloads at very high TDP
- Platform is still new; early firmware and driver stacks are maturing
- Higher‑end X9 model offers more GPU and CPU headroom in the same family
Pros
- Arc B390 iGPU is a huge leap for integrated graphics, enabling 1080p gaming without a dGPU in many titles.
- 50 TOPS NPU plus GPU AI acceleration make it a strong platform for on‑device AI and Copilot+ features.
- 25 W base power and Intel 18A deliver much better efficiency than old high‑power mobile Intel chips.
- LPDDR5X‑9600 and 96 GB support give ample memory bandwidth and capacity for integrated graphics and AI.
- Thunderbolt 4, Wi‑Fi 7, and modern I/O are welcome on a premium mobile platform.
Cons
- CPU performance gains over Arrow Lake‑H are modest; this generation is more about iGPU and AI than raw CPU speed.
- 12 PCIe lanes limit multi‑GPU or heavy NVMe configurations compared to HX‑class chips.
- Real‑world performance depends heavily on OEM power limits and cooling; some laptops may throttle under sustained load.
- Locked multiplier means no enthusiast overclocking.
- Arc B390 drivers and XeSS ecosystem are still maturing; some titles need tweaks for best results.
