The GEEKOM IT12 and IT15 sit at opposite ends of GEEKOM’s Intel lineup: the IT12 runs a 12th Gen i5-12450H at ~$399–449, while the IT15 runs Intel’s Core Ultra 9 285H with an Arc 140T discrete GPU at ~$649–749. Both machines share GEEKOM’s 3-year warranty and SO-DIMM upgradeable RAM — competitive advantages that matter when you’re comparing against brands with shorter support commitments. The question is whether the IT15’s 15th Gen CPU, integrated Arc GPU, dual 2.5GbE, and WiFi 7 justify paying $200–300 more than the IT12.

Quick Verdict

The IT12 is the best-value Intel mini PC under $450 with a 3-year warranty — hard to beat for office work, light homelab, or Plex. The IT15 is the choice when you need Arc 140T GPU acceleration, dual 2.5GbE networking, or the generational CPU uplift that 15th Gen Core Ultra delivers over 12th Gen.

The IT12 is one of the most compelling budget Intel mini PCs on the market when you factor in the 3-year warranty. Most mini PCs at this price ship with 1-year coverage — GEEKOM’s 3-year commitment means if something goes wrong in year two, you’re covered. That policy changes the value calculus meaningfully for anyone running this as a 24/7 home server or primary desktop.

The i5-12450H is a proven 12th Gen chip: 8 cores, 12 threads, Intel Quick Sync for hardware video decode, and a TDP that stays well-managed in the compact IT12 chassis. For Plex transcoding, Docker containers, Home Assistant, Jellyfin, and general office use, the i5-12450H handles the workload without complaint. Community measurements show idle power around 8W, which puts the annual electricity cost at roughly $8/year for always-on use — lower than most alternatives in this class.

RAM comes on DDR5 SO-DIMM slots, so you can upgrade from the base 16GB or 32GB config as prices continue to fall. Single 2.5GbE NIC covers most home network needs, though it rules out dual-NIC homelab builds. WiFi 6E keeps wireless performance strong. The IT12 is a machine you buy when the workload is modest and the warranty matters.

Pros:

• 3-year warranty — rare at this price tier among mini PC brands
• ~8W idle keeps annual electricity cost near $8/year for always-on use
• DDR5 SO-DIMM RAM is user-upgradeable to 64GB
• Intel Quick Sync enables hardware video decode for Plex and Jellyfin
• Proven platform with strong community support for Linux and Proxmox

Cons:

• Single 2.5GbE NIC limits homelab networking options
• 12th Gen Core i5 is two generations behind the IT15’s Core Ultra 9
• No discrete GPU — Intel Xe iGPU only, which limits gaming and GPU-accelerated AI
• WiFi 6E rather than WiFi 7

GEEKOM IT15

The IT15 is GEEKOM’s current flagship: Intel Core Ultra 9 285H, Arc 140T GPU, 32GB DDR5, dual 2.5GbE, WiFi 7, and 8K quad-display output in a form factor similar to the IT12. The Core Ultra 9 285H is a 15th Gen Arrow Lake chip with 24 cores and 24 threads — a significant architecture step beyond the IT12’s i5-12450H. More importantly, the Arc 140T GPU is a discrete Intel GPU with dedicated VRAM and full hardware AV1 encode/decode support, which matters for 4K content creation, streaming, and GPU-accelerated workloads.

Dual 2.5GbE is the networking upgrade that matters most for homelab builders. With two 2.5GbE ports, you can split WAN and LAN for a basic OPNsense setup, run a dedicated storage link to a NAS, or bond the two NICs for 5Gbps aggregate throughput on a compatible switch. WiFi 7 adds multi-link operation for better wireless performance in congested environments.

GEEKOM ships the IT15 with 2TB SSD standard, a generous inclusion at this price. The 3-year warranty carries over from the IT12 — so you get GEEKOM’s extended support commitment on the more premium platform as well. For users who need the Arc GPU for compute or encoding, or who specifically want dual 2.5GbE and WiFi 7, the IT15 is the only Intel mini PC in GEEKOM’s lineup that delivers all three.

Pros:

• Arc 140T GPU with dedicated compute units for hardware AV1 encode and GPU workloads
• Dual 2.5GbE NICs for homelab network segmentation or storage bonding
• Core Ultra 9 285H with 24C/24T — substantially more headroom than the IT12’s i5
• WiFi 7 for multi-link wireless operation and higher throughput
• 8K quad-display output for demanding multi-monitor setups
• 3-year warranty — same as the IT12, which is uncommon at this price

Cons:

• ~$200–300 premium over the IT12 for users whose workloads don’t use Arc GPU or dual NICs
• ~12W idle vs. ~8W on the IT12 — costs ~$4/year more to run always-on
• Arc 140T is competitive but not a gaming GPU — don’t expect 1080p high settings in AAA titles
• Core Ultra 9 285H thermal management requires headroom in the chassis under sustained load

Head-to-Head by Use Case

For Home Server and Light Virtualization

Winner: GEEKOM IT12 — For Plex, Docker, Jellyfin, or a lightweight Proxmox setup with 2–3 containers, the IT12’s i5-12450H is fully capable and costs $200 less. The 3-year warranty at this price tier is the deciding factor for always-on use.

For GPU-Accelerated Workloads and Content Creation

Winner: GEEKOM IT15 — The Arc 140T GPU with hardware AV1 encode/decode is the IT15’s defining advantage. For Handbrake encoding, OBS streaming with GPU encode, ComfyUI, or any workload that can use Intel Arc compute, the IT15 is in a different category from the IT12.

For Homelab Networking

Winner: GEEKOM IT15 — Dual 2.5GbE enables network segmentation and multi-path storage that the IT12’s single NIC cannot support. If your homelab benefits from a dedicated storage link or a proper WAN/LAN split, the IT15’s dual NICs are worth the premium.

Power and Yearly Running Cost

The IT12’s lower idle draw reflects the efficiency advantage of a simpler platform — no discrete GPU controller, single NIC, and a mobile i5 optimized for low-power operation. The IT15 draws more at idle due to the Arc GPU and second NIC. For always-on home server use, the difference is about $5/year at $0.12/kWh.

Final Verdict

Buy the GEEKOM IT12 if: your workload fits a capable 12th Gen Intel mini PC — Plex, Docker, light Proxmox, or office desktop use — and you want the best combination of price, 3-year warranty, and low idle power under $450.

Buy the GEEKOM IT15 if: you need the Arc 140T GPU for hardware-accelerated encode or compute, dual 2.5GbE for homelab networking, or the generational performance uplift from Core Ultra 9 285H over 12th Gen Core i5.

Frequently Asked Questions

Which option wins for geekom it12 vs it15?

For budget-conscious buyers running Plex, Docker, or a home desktop, the IT12 wins on value with identical warranty coverage and much lower price. For GPU-accelerated workloads or dual-NIC homelab networking, the IT15 delivers capabilities the IT12 simply doesn’t have.

Should you buy now or wait for the next refresh?

The IT15’s Core Ultra 9 285H is current-generation 15th Gen Intel. A successor is unlikely before 2026–2027. Both machines are mature platforms worth buying now — there’s no refresh imminent for either.

What matters more than the headline CPU?

For most buyers comparing these two machines, the GPU is the key differentiator — Arc 140T vs. Intel Xe iGPU is a significant capability gap for encoding and compute workloads. After that, networking matters: single vs. dual 2.5GbE is the deciding factor for homelab use cases.
