Processor: Intel Core Ultra 7 255H (Arrow Lake-H)
This chip is the heart of the "AI PC" era, moving away from high-wattage raw speed toward intelligent, efficient performance.
Cores: 16 Cores (6 Performance-cores, 8 Efficiency-cores, 2 Low-power E-cores).
Threads: 16 (Intel has moved away from Hyper-threading in this generation for better per-core efficiency).
Max Clock Speed: Up to 5.1 GHz.
TDP: Optimized at 28W - 40W (configurable) but can boost up to 115W for heavy bursts.
AI Engine (NPU): Includes Intel® AI Boost, delivering approximately 13 NPU TOPS and up to 99 Total Platform TOPS (CPU+GPU+NPU) for local AI tasks like background blur, live translation, and LLM acceleration.
Graphics: Intel Arc 140T GPU
The "T" designation refers to the 2nd generation Xe architecture integrated into the Arrow Lake mobile chips.
Architecture: 8 Xe-cores (Xe²-LPG).
Performance: Roughly 10-15% faster than the previous Meteor Lake Arc graphics.
Capabilities: Full support for AV1 hardware encoding/decoding, Ray Tracing, and XeSS AI upscaling. It can comfortably handle light gaming, 4K video editing, and complex creative apps.
Connectivity & Expansion
Despite its small size, the NUC 15 Pro is packed with desktop-class I/O.
Display Support: Up to four 4K@60Hz displays simultaneously via 2x HDMI 2.1 and 2x Thunderbolt 4 ports.
Memory Slots: 2x SODIMM slots supporting up to 96GB of DDR5-6400MHz RAM.
Storage Slots:
Slot 1: M.2 2280 NVMe supporting PCIe Gen5 x4 (ultra-fast SSDs).
Slot 2: M.2 2242 NVMe supporting PCIe Gen4 x4.
Networking:
Intel Wi-Fi 7 (BE201/BE202) for multi-gigabit wireless speeds.
2.5Gb Ethernet (Intel I226-V) for stable wired connections.
Ports: 3x USB 3.2 Gen2 Type-A, 1x USB 3.2 Gen2x2 Type-C (front), 1x USB 2.0 (rear), and 2x Thunderbolt 4.
Physical Options: Tall (H) vs. Slim (K)
Tall Model (RNUC15CRH): Roughly 54mm height. It features extra internal headers for expansion (like a second LAN port or serial port) and better thermal headroom for prolonged AI workloads.
Slim Model (RNUC15CRK): Roughly 37mm height. Ideal for VESA mounting behind a monitor where space is the primary concern.
