ASUS NUC 16 PRO Intel Ultra x9 388H/ LPDDR5 64GB/ 1TB/ Win 11 Pro
PRODUCT DESCRIPTION
ASUS NUC 16 Pro Intel Core Ultra X9 388H / LPDDR5 64GB / 1TB SSD / Windows 11 Pro (RNUC16GDKX96D4N3) - 3 Years Onsite Local Warranty
The Top Configuration in the NUC 16 Pro Business PC Range
The ASUS NUC 16 PRO RNUC16GDKX96D4N3 is a complete Windows 11 Pro system and the highest-specification configuration ASUS offers in the NUC 16 Pro line: the Intel Core Ultra X9 388H processor, 64 GB of high-bandwidth LPDDR5x memory and a 1 TB NVMe SSD are already fitted, ready to sign in as soon as a monitor, keyboard and mouse are connected. This is the SKU to buy when memory capacity, not processor tier, is the constraint — local AI model work, memory-heavy virtualisation, or large in-memory datasets that a 32 GB machine would struggle with.
Intel Core Ultra X9 388H — Panther Lake, Intel Arc B390 Graphics
The Core Ultra X9 388H is a 16-core processor and the highest processor tier ASUS fits to the NUC 16 Pro, paired with an Intel Arc B390 integrated GPU across the Panther Lake tier of this range. Its advantage over the Core Ultra X7 358H one step below it is a higher clock ceiling for sustained CPU-bound work — video encoding, compilation, virtualisation and similar tasks — while both share the same GPU and NPU. The on-chip Intel AI Boost NPU is the Panther Lake generation, a step up from the earlier-platform Core Ultra 5/7 configurations elsewhere in our catalogue.
64 GB Soldered LPDDR5x — the Largest Capacity in the Range
Memory ships as 64 GB of LPDDR5x, soldered directly to the board rather than fitted as removable SO-DIMM modules. LPDDR5x runs at materially higher effective bandwidth than DDR5 SO-DIMM, which matters directly to the Arc B390 GPU that draws all its bandwidth from system memory. 64 GB is the largest memory configuration ASUS offers on the NUC 16 Pro, and the trade-off of soldered memory is that this capacity is fixed at the factory — there is no field upgrade path, so this SKU is the one to order up front if your workload might need it, rather than the 32 GB sibling (RNUC16GDKX96C4N3).
1 TB NVMe SSD, Storage Expansion Available
Storage is a 1 TB M.2 NVMe PCIe SSD. Unlike the soldered memory, storage on this chassis remains a conventional M.2 slot, and the platform supports additional M.2 storage if 1 TB is eventually outgrown — ask SourceIT to fit a second drive before delivery.
Dual Thunderbolt 4, Dual HDMI 2.1, Dual 2.5G LAN
Display output is two Thunderbolt 4 Type-C ports (DisplayPort 2.1 capable) plus two HDMI 2.1 ports. Wired networking is dual Intel I226-V 2.5 Gigabit Ethernet, wireless is Intel Wi-Fi 7 with Bluetooth 6.0. The chassis measures a compact 144 x 117 x 42 mm.
Deploying a Fleet Across Both Platform Tiers
Because ASUS kept the external chassis dimensions and VESA mounting pattern identical across both the SO-DIMM and Panther Lake tiers of the NUC 16 Pro, a Singapore business that needs to mix this flagship configuration on selected desks with lower-cost Core Ultra 5/7 SO-DIMM units elsewhere in the same fleet does not need to plan different mounting hardware or desk clearances. The physical deployment story stays consistent even though the internal platform, memory type and GPU differ substantially between tiers.
Supplied Locally, with GST Invoice and Singapore Onsite Warranty
SourceIT supplies the ASUS NUC 16 PRO RNUC16GDKX96D4N3 with a full GST invoice and local Singapore support. ASUS backs this system with a 3-year onsite warranty, so a qualifying hardware fault is resolved at your premises rather than a courier round trip.
Do not need 64 GB and would rather save on the 32 GB configuration? Our ASUS NUC 16 PRO RNUC16GDKX96C4N3 is the identical Core Ultra X9 388H build with 32 GB of LPDDR5x instead. Email sales@sourceit.com.sg and we will help you pick the right memory tier.

Connectivity & Setup / Expansion
Why Choose 64 GB Over 32 GB
Memory on this Panther Lake tier is soldered LPDDR5x with no field upgrade path, so capacity has to be decided at order time. This SKU is the 64 GB configuration — the largest ASUS offers on the NUC 16 Pro — and is the right choice for local AI model inference, memory-heavy virtualisation with several concurrent VMs, or large in-memory datasets. If your workload is comfortably within 32 GB, the identical processor is also available at that capacity as RNUC16GDKX96C4N3, at lower cost.
Storage Upgrade Path
The 1 TB primary SSD sits in a tool-less M.2 bay, and the platform supports additional M.2 storage. Ask SourceIT to supply and fit a second drive before delivery if you would rather not open the chassis later.
Dual 2.5G LAN and Networking Setup
Two Intel I226-V 2.5 Gigabit Ethernet ports are fitted as standard on this range — useful for a failover WAN connection or a lightweight two-port gateway role. Wireless is Intel Wi-Fi 7 with Bluetooth 6.0.
CPU Headroom Over the Core Ultra X7 358H
Both X7 and X9 Panther Lake configurations share the same Arc B390 GPU and NPU. The X9 388H's advantage over the X7 358H is on the CPU side — a higher clock ceiling that benefits sustained CPU-bound work more than everyday office use.
Sizing Memory Correctly the First Time
Because this tier cannot be upgraded after purchase, it is worth spending a moment on sizing before ordering rather than after. If your current workload is comfortably inside 32 GB — general office use, a handful of VMs, typical browser and productivity load — the 32 GB sibling (RNUC16GDKX96C4N3) saves cost for identical CPU and GPU performance. If you are running local AI inference on models in the tens of gigabytes, several concurrent VMs each with their own memory allocation, or large in-memory data processing, 64 GB is the safer starting point. Email us your workload and we will help you decide rather than guess.

Frequently Asked Questions — ASUS NUC 16 PRO RNUC16GDKX96D4N3
Is this a complete system or a barebone unit?
Complete system. It ships with the Intel Core Ultra X9 388H processor, 64 GB LPDDR5x memory and a 1 TB NVMe SSD already fitted, with Windows 11 Pro pre-installed and ready for first sign-in.
How does this compare with the RNUC16GDKX96C4N3 configuration?
Identical processor, storage and connectivity — the only difference is memory. This SKU ships with 64 GB of LPDDR5x; RNUC16GDKX96C4N3 ships with 32 GB. Choose based on whether your workload will benefit from the larger capacity.
Can I upgrade the memory later?
No. Memory on this Panther Lake tier is soldered to the board and is not field-upgradeable — 64 GB on this SKU is fixed from the factory, which is exactly why it is worth ordering up front if you expect to need it.
Can I upgrade the storage?
Yes. Storage remains a conventional M.2 slot, and the platform supports additional M.2 storage alongside the 1 TB primary drive. Ask SourceIT to supply and fit it before delivery.
Is this the largest memory configuration you sell on the NUC 16 Pro?
Yes. 64 GB is the largest capacity ASUS offers on this range.
Does it have dual LAN?
Yes — two Intel I226-V 2.5 Gigabit Ethernet ports are standard on this range, useful for a failover link or a lightweight gateway role.
How many monitors can it drive?
Four displays across two Thunderbolt 4 (DisplayPort 2.1) ports and two HDMI 2.1 ports.
Can I mix this with SO-DIMM tier units in the same fleet?
Yes, physically. The external chassis dimensions and VESA mounting pattern are identical across both platform tiers of the NUC 16 Pro, so desk fit-out and mounting hardware do not need to differ even when the internal platform, memory type and GPU do.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS NUC 16 PRO RNUC16GDKX96D4N3 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year onsite warranty.
