PRODUCT DESCRIPTION
ASUS ROG GR70 (GR70-N90038AN) - 3 Years Local Warranty
An AMD Ryzen 9 9955HX3D Gaming Desktop — in a 3-Litre Mini PC Chassis, Not a Tower
The ASUS ROG GR70 GR70-N90038AN is a genuinely different platform from the Intel-based ROG NUC range: it pairs an AMD Ryzen 9 9955HX3D processor with 3D V-Cache against an NVIDIA GeForce RTX 5070 Laptop GPU, in a chassis of roughly the same compact footprint as the ROG NUC line — about 282 x 188 x 57 mm and 2.75 kg. Note for anyone searching for a "ROG GR70 gaming desktop tower" expecting a full ATX case: ASUS itself markets and specifies the GR70 as a mini PC, not a tower, and its own dimensions confirm a chassis under 3 litres. It is the AMD-platform counterpart to the Intel ROG NUC range, built for an AMD Ryzen 9 9955HX3D gaming PC buyer who wants that specific CPU rather than a different chassis category.
32 GB of DDR5-5600 memory and a 1 TB NVMe SSD ship as standard, Windows 11 Pro is pre-installed on this configuration, and the system is ready to run out of the box.
AMD Ryzen 9 9955HX3D — 16 Cores, 32 Threads, 3D V-Cache
The Ryzen 9 9955HX3D is a 16-core, 32-thread processor on AMD's Zen 5 architecture, with a base clock of 2.5 GHz and boost up to 5.4 GHz, running at a configurable 55–75 W TDP with turbo power up to around 101 W. AMD's own material for this chip describes up to 144 MB of total cache including 2nd-generation AMD 3D V-Cache — the stacked cache technology that gives X3D-branded chips a real advantage in CPU-bound games over an equivalent non-3D part, because more of the game's working data stays close to the cores instead of round-tripping to system memory.
NVIDIA GeForce RTX 5070 Laptop GPU — 4,608 CUDA Cores, 798 AI TOPS
The discrete GPU is the RTX 5070 Laptop GPU: 8 GB of GDDR7 memory, 4,608 CUDA cores on NVIDIA's Blackwell architecture, and 798 AI TOPS. NVIDIA's published TGP range for this GPU tier runs 50–100 W; ASUS does not break out the exact figure configured for this chassis. That is a mid-tier mobile GPU, suited to 1440p gaming with DLSS 4 and ray tracing enabled rather than native 4K — the GR70 range also offers an RTX 5060 configuration below this one.
32 GB DDR5-5600, Dual Channel, with a Second M.2 Slot in Reserve
Memory ships as 32 GB across two SO-DIMM modules running at DDR5-5600, dual channel, with ASUS's specification page quoting a maximum capacity of 96 GB (48 GB x 2). Storage is a 1 TB M.2 2280 NVMe PCIe 4.0 SSD, with ASUS's toolless Q-Latch design making both memory and the second, empty M.2 slot straightforward to access without disassembling the whole chassis — a genuine convenience in a chassis this compact, and one the GR70 shares with the ROG NUC line despite the different CPU platform underneath.
ROG QuietFlow Triple-Fan Cooling, MIL-STD 810H Tested
ASUS cools the GR70 with its ROG QuietFlow triple-fan and heatpipe design, and states in its own product materials that noise stays below 4.5 dB(A) above ambient under normal conditions — a figure we quote as ASUS's own published claim rather than an independently verified one. The chassis has passed MIL-STD 810H durability testing, the same military-derived standard for shock, vibration and environmental stress applied across ASUS's current ROG mini PC range.
Supplied Locally, with GST Invoice and Singapore Warranty
SourceIT supplies the ROG GR70 GR70-N90038AN with a full GST invoice and local Singapore warranty support, backed by ASUS's 3-year warranty term for this range.

Connectivity & Setup / Thermal Design
Not a Tower — What "Compact AMD Gaming Desktop" Actually Means Here
It is worth being direct about this: despite carrying "gaming desktop" branding and the GR70 model name inviting comparison with a tower PC, ASUS's own specification and overview pages describe and dimension the GR70 as a mini PC — the same roughly 3-litre, sub-3 kg chassis class as the Intel ROG NUC range, not a full ATX or micro-ATX case with multiple drive bays, a full-size PSU or discrete liquid-cooling radiator mounts. If you are comparing this against a traditional gaming tower, expect the compact-chassis trade-offs that come with it: laptop-class GPU rather than a full desktop card, external power brick rather than an internal PSU, and two M.2 slots rather than multiple 3.5-inch and 2.5-inch drive bays.
Cooling and Noise Under Load
The ROG QuietFlow triple-fan and heatpipe system is the same cooling philosophy ASUS applies across its current ROG mini PC range, tuned here for the AMD Ryzen 9 9955HX3D and RTX 5070 combination. ASUS's own published figure states noise stays below 4.5 dB(A) above ambient under normal conditions — we pass this on as ASUS's claim rather than an independently measured figure, and would expect fan noise to rise audibly during sustained gaming, as it does on comparable compact chassis from this manufacturer.
Upgrade Headroom Versus a Full Tower
Where the GR70 does offer genuine upgrade headroom for its class is memory and storage: ASUS's toolless Q-Latch design gives straightforward access to both SO-DIMM slots (up to 96 GB total) and both M.2 2280 slots (a second slot supporting up to 2 TB PCIe 5.0 on top of the 1 TB fitted). What it does not offer, because of the chassis category, is GPU or PSU upgrades — the RTX 5070 Laptop GPU and 330 W external adapter are fixed for the life of the system, which is the trade-off against a genuine gaming tower's open PCIe slots and swappable power supply.
Networking and Display Outputs
Wired networking is 2.5 Gigabit Ethernet, with Wi-Fi 7 (Gig+) and Bluetooth 5.4 for wireless. Display output covers two HDMI 2.1, two DisplayPort 2.1 and one rear USB4 Type-C port carrying DisplayPort 1.4, supporting up to five simultaneous displays — useful for a trading-desk or multi-monitor productivity setup as well as gaming.

Frequently Asked Questions — ASUS ROG GR70 GR70-N90038AN
Is the ROG GR70 a full tower gaming PC?
No. Despite the "gaming desktop" branding, ASUS specifies and markets the GR70 as a mini PC — roughly 282 x 188 x 57 mm and 2.75 kg, the same compact chassis class as the Intel ROG NUC range. If you are looking for a full ATX tower with multiple drive bays and an internal PSU, this is not that product; it is a compact AMD-platform alternative to the Intel ROG NUC.
What does the 3D V-Cache on the Ryzen 9 9955HX3D actually do?
It stacks additional cache directly on the CPU die, which AMD states brings total cache up to 144 MB on this chip. In CPU-bound games, keeping more of the game's working data close to the cores rather than fetching it from system memory produces a real, measurable frame-rate advantage over an equivalent non-3D Ryzen chip — this is the main reason to choose the 9955HX3D configuration specifically.
Is the RTX 5070 in this the same as a desktop RTX 5070 card?
No — it is the RTX 5070 Laptop GPU, an 8 GB GDDR7 mobile-class part with 4,608 CUDA cores and a 50–100 W configurable TGP per NVIDIA's published range. It targets 1440p gaming with DLSS 4 rather than native 4K, and it is a meaningfully smaller GPU than a desktop RTX 5070 card would be in a full tower.
Can I upgrade the GPU or add a second graphics card later?
No. Because this is a compact mini PC chassis rather than a tower, the GPU is a fixed laptop-class module and there are no open PCIe slots for a discrete desktop card. Memory and storage are the genuine upgrade paths — both SO-DIMM slots and a second M.2 2280 slot are accessible without special tools.
Why does this configuration ship with Windows 11 Pro rather than Home?
This is how ASUS configures the GR70-N90038AN SKU specifically; other GR70 configurations in the wider ASUS lineup may ship with Windows 11 Home instead. Check the SKU on the box or the invoice if the OS edition matters for your deployment.
How does this compare with the Intel-platform ROG NUC range?
Both families sit in a similar compact chassis class with laptop-class discrete GPUs, but the GR70 runs an AMD Ryzen 9 9955HX3D with 3D V-Cache instead of an Intel Core Ultra HX processor. The 3D V-Cache gives the GR70 an edge in CPU-bound, cache-sensitive games; the Intel ROG NUC range offers higher GPU tiers (up to RTX 5080) that this particular GR70 configuration does not match with its RTX 5070.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ROG GR70 GR70-N90038AN sold by SourceIT comes with local Singapore warranty support and a GST invoice; ASUS backs this system with a 3-year warranty.
