AI / ML
- Dedicated NPU 5 with 47 INT8 TOPS accelerates Windows Studio Effects and local AI models.
- CPU and GPU also support DL Boost and XMX-based AI workloads, but TOPS are lower than on higher-end Ultra 7/9 models.
- Well suited for consumer AI features and small models, not for training or large-scale inference.
- NPU 5 with 50 TOPS INT8 and strong GPU AI throughput.
- Intel shows up to ~5.5× better GPU AI vs older Raptor Lake‑P and large leads vs some AMD Strix Point competitors in Geekbench AI and UL Procyon AI workloads.
- Well suited for local small‑medium LLMs, AI background effects and image generation.
Content Creation
Gaming
- Arc B370 10 Xe3 cores at up to 2.4 GHz deliver roughly 70% more performance than Intel’s previous Arc 140V/140T iGPUs and comfortably outpace AMD’s Radeon 890M in synthetic tests.
- At 35 W, the B370’s Time Spy Graphics score is around 5,933 points, placing it between older RTX 3050 Ti and RTX 4050 laptop GPUs in some scenarios.
- Best suited for 1080p medium settings; more demanding AAA titles may require resolution scaling or lower presets.
- 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.

Strengths & Weaknesses
Pros
- Major leap in integrated GPU performance vs older Intel iGPUs
- Good single-threaded performance for everyday and lightly threaded workloads
- 12-core design provides solid multi-core throughput for the TDP
- NPU accelerates AI features without heavily loading CPU or GPU
- 25 W base power enables thin-and-light designs with decent battery life
- Modern I/O: PCIe 5.0, Thunderbolt 4, LPDDR5X, Wi-Fi 7 (platform dependent)
Cons
- Not intended for heavy sustained multi-threaded workloads like high-end rendering
- iGPU still falls short of low-end discrete GPUs like RTX 4050 in more demanding games
- Locked multiplier limits overclocking headroom
- Actual performance and thermals depend heavily on laptop OEM power tuning
- New platform; early firmware and drivers may still be maturing
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
