Design & Build Quality

The GEEKOM IT15 continues GEEKOM’s premium aesthetic — minimalist, brushed-metal chassis with diamond-cut edges and a dense, professional feel. Despite its immense hardware, it retains a 0.9-liter footprint that fits in your palm or mounts seamlessly behind a display via VESA mount support.

Ventilation is smartly engineered with dual-sided airflow channels and a quiet high-static-pressure fan. Even during full CPU/GPU load, thermal performance stays stable while maintaining low noise levels.

Every detail — from its tactile power button to its rounded aluminum corners — reflects GEEKOM’s push toward premium workstation quality in a mini-PC size.


Processor & AI Performance

At the heart of the IT15 lies the Intel Ultra 9 285H, Intel’s flagship 15th-generation mobile processor (Meteor Lake refresh) featuring:

  • 16 cores (6 P-cores + 10 E-cores) / 22 threads
  • Up to 5.1 GHz boost clock
  • Integrated AI Boost NPU delivering 99 TOPS of AI compute (CPU + GPU + NPU combined)
  • Intel Arc 140T GPU with full XeSS and ray-tracing support

This configuration pushes the IT15 into workstation territory — capable of real-time 8K video editing, AI model inference, 3D rendering, and high-thread-count multitasking without breaking a sweat.

In benchmarks, the Ultra 9 285H outperforms most previous-gen desktop Core i9 mobile chips while consuming far less power, making it one of the most efficient high-performance CPUs available in a mini form factor.


Memory & Storage

The IT15 includes 32 GB DDR5-5600 MHz RAM in dual-channel configuration for maximum bandwidth and responsiveness. The system supports up to 64 GB DDR5, ensuring future scalability for memory-intensive workflows.

Storage is handled by a 2 TB PCIe Gen 4 NVMe SSD (7000 MB/s read, 6500 MB/s write). Two M.2 slots allow expansion up to 8 TB total capacity, ideal for professionals managing large 8K video files, datasets, or high-resolution creative projects.

This combination makes the IT15 an exceptional choice for both performance-heavy and data-centric tasks.


Graphics & Display Support

The integrated Intel Arc 140T GPU sets a new standard for graphics performance in mini PCs. It features 8 Xe cores, hardware-based ray tracing, AV1 encoding/decoding, and 8K 120 Hz output support.

Key capabilities:

  • Drives up to four displays simultaneously at 4K 60 Hz or one 8K 120 Hz monitor
  • HDMI 2.1 + dual Thunderbolt 4 outputs for next-gen monitors and VR setups
  • GPU acceleration for AI inference, video editing, and photo processing
  • Support for Intel XeSS AI upscaling, improving gaming frame rates and image clarity

In real-world usage, the Arc 140T performs on par with entry-level discrete GPUs such as RTX 2050/3050, making it perfectly suited for lightweight gaming, creative rendering, and 8K media playback.


Connectivity & Ports

The GEEKOM IT15 offers one of the most comprehensive port layouts in the mini-PC market:

  • 2 × Thunderbolt 4 (Type-C) – DisplayPort + Power Delivery
  • 2 × HDMI 2.1 – 4K/8K output
  • 3 × USB-A 3.2 Gen 2
  • 1 × USB-A 2.0
  • 2.5 Gb Ethernet Port
  • Wi-Fi 7 (802.11be) + Bluetooth 5.4
  • 3.5 mm audio combo jack
  • SD Card Reader for creators

The inclusion of Wi-Fi 7 provides multi-gigabit wireless throughput, lower latency, and greater network stability than Wi-Fi 6/6E — perfect for next-gen routers and AI cloud workflows.


Real-World Performance

In day-to-day work, the IT15 feels like a full desktop workstation. Boot time is under 6 seconds, and heavy apps such as DaVinci Resolve, Blender, and Adobe Premiere Pro open instantly.

AI-powered tasks like background removal, real-time transcription, and on-device image generation benefit greatly from the Intel AI Boost NPU, cutting render times by 30–50% compared to traditional CPU workflows.

Gaming performance is impressive for its size — titles such as Valorant, GTA V, and Cyberpunk 2077 run smoothly at 1080p High settings with XeSS enabled. Thermal management is excellent, maintaining boost clocks without throttling during sustained loads.

For creative professionals, it drives multiple 4K monitors effortlessly while maintaining silent operation, making it perfect for multi-display productivity setups.


AI Acceleration & Next-Gen Efficiency

The defining advantage of the Intel Ultra 9 285H platform is its on-chip AI Boost NPU delivering up to 99 TOPS of AI compute.

This enables the IT15 to:

  • Accelerate local AI workloads like image enhancement, voice recognition, or object detection.
  • Run AI copilot apps (Windows Copilot, Adobe Sensei AI, DaVinci Neural Engine) faster and more efficiently.
  • Deliver hybrid CPU + GPU + NPU acceleration for machine-learning developers and power users.

As AI becomes more integrated into everyday workflows, this hardware foundation gives the IT15 lasting relevance beyond typical mini PCs.
