ASUS ROG GR70 Mini Gaming PC Review

Small Form Factor (SFF) PCs has been very popular ever since the mini ITX motherboards became mainstream. It is extremely satisfying to own a powerful machine at the fraction size of a giant desktop tower. The ASUS ROG GR70 takes the concept even further. It borrows the main components from a high-end gaming laptop but sticks them inside a sub-three-liter mini PC chassis. The idea is simple: give these mobile parts more physical breathing room so they can run faster and quieter than they ever could in a cramped laptop shell.

After testing the top-spec model—packing an AMD Ryzen 9 9955HX3D, an RTX 5070 laptop GPU, 32GB of RAM, and a 1TB SSD—it’s clear that ASUS mostly nailed the execution.

The 3-Liter Desktop-Saving Setup

Out of the box, the GR70 is incredibly small. Measuring roughly 282 x 187 mm and just 56 mm thick, it can sit vertically next to your monitor or slip horizontally under it (removing the feet). If you are trying to clean up your desk space, it’s an absolute game-changer.

The look is pure ROG: sharp angles, a lightbar, and customizable RGB side panels that add some flair without looking entirely like a toy.

But there is a catch to this ultra-small footprint. To feed the power-hungry internals, ASUS includes a massive 330W external power brick, just like any high-performance gaming laptops. For desktop setups, you could hide this giant block somewhere under your desk or cable management tray.

On the bright side, the I/O selection is fantastic. Mini PCs usually force you to live the dongle life, but the GR70 is loaded:

• 1x 3.5mm combo audio jack
• 1x USB-C
• 2x USB-A

Around the back:, there’s a full USB4 Type-C port, four fast USB-A ports, two HDMI 2.1 ports, and two DisplayPort 2.1 connections.

• 2x HDMI 2.1
• 2x DisplayPort 2.1
• 1x USB-C (USB4 40Gbps)
• 1x 2.5G Ethernet
• 4x USB-A (10Gbps)

You can literally run five monitors off this tiny box if you really wanted to.

Surprisingly Great Performance and Thermals

Here is what the 3DMark score translates to in terms of equivalent hardware:

Equivalent Graphics Cards

Taking Speed Way test as baseline, it sits between a stock Desktop RTX 4060 Ti (which typically scores around 3,200) and a stock Desktop RTX 4070 (which usually pushes closer to 4,400).

Real-World Performance Profile

Achieving a 3,745 in Speed Way translates to a very capable, upper-mid-range gaming profile:

• 1440p Gaming: This is the sweet spot for this level of performance. You can comfortably run modern AAA titles at 1440p on High/Ultra settings, clearing 60+ FPS easily in native rendering, and pushing past 100+ FPS when utilizing DLSS/Frame Generation.
• Ray Tracing: Because Speed Way is heavily ray-traced, a score of 3,745 confirms the GPU architecture handles hardware-accelerated ray tracing efficiently without completely tanking the frame rate, though turning on DLSS is still recommended for heavy titles like Cyberpunk 2077 or Alan Wake 2.
• 4K Gaming: It can handle 4K, but you will be heavily reliant on aggressive upscaling (DLSS Performance mode) and lowering a few settings to hold a stable 60 FPS.

Cyberpunk 2077 ingame benchmark shows it is indeed struggling when you max out the settings (4K + Ray Tracing: Overdrive). Without Frame Generation, you will not be getting a stable 30fps. Honestly it is fine because this hardware is not meant to push 4K at such a demanding settings.

Instead, once our turn down the resolution to 1080p, the experience is a whole lot different than before.

By giving the Ryzen 9 9955HX3D and the mobile RTX 5070 a little more physical room, ASUS can push their power limits higher than a standard laptop chassis would allow. The X3D chip, featuring AMD’s 3D V-Cache, handles frame pacing beautifully, while the RTX 5070 leverages DLSS 4 to handle heavy AAA titles and demanding ray-traced workloads without breaking a sweat.

The biggest surprise is the noise—or lack of it. Laptop components in tiny spaces usually sound like a jet engine taking off. However, the GR70 uses a custom triple-fan “QuietFlow” system. Because it has thicker heatpipes and way more ventilation space than a thin laptop, the fans don’t need to spin at an obnoxious, high-pitched whine to keep things cool. The CPU can still run warm during heavy, sustained all-core production rendering, but during standard gaming sessions, the thermals remain highly stable and the noise stays well-managed.

In terms of upgradability and maintenance, users can access the internal components relatively easily by unscrewing one thumbscrew and removing the chassis. There’s a vacant M.2 slot for future storage upgrades and the SODIMM slots are easily accessible.

Malaysian Configuration and Pricing

In Malaysia, ASUS has brought in the exact high-end configuration tested here, and it carries the usual premium price tag associated with niche small-form-factor (SFF) engineering.

• AMD Ryzen 9 9955HX3D
• NVIDIA GeForce RTX 5070 Laptop (8GB GDDR6)
• 32GB DDR5
• 1TB PCIe 4.0 SSD

Official Malaysian Price: RM11,999

It comes bundled with a standard 3-year local onsite warranty from ASUS Malaysia, which provides some welcome peace of mind considering the highly integrated, proprietary nature of the motherboard and cooling setup.

The Verdict: Who Should Actually Buy This?

The ROG GR70 is a specialized piece of hardware. At just under RM12,000, it carries a heavy premium over a traditional DIY desktop tower with similar performance.

You should buy this if:

• The Space-Constrained Streamer / Condo Resident: You live in a tight apartment or dorm, hate bulky desktop towers, but still want a permanent, high-performance multi-monitor setup without losing your desk space.
• The “Fixed-Location” Traveler: You frequently move between two fixed setups (like traveling between your hometown and a rental room, or home and the office) and want high-end desktop power you can throw in a backpack, provided you don’t mind the weight of the power brick.
• The SFF Enthusiast with No Time: You love the mini-ITX aesthetic and clean setups, but you absolutely do not want the headache, component hunting, and cable management frustrations of building a custom small-form-factor PC yourself.

You should skip this if:

• You are looking for raw performance-per-ringgit. For RM12,000, you can easily build a mid-tower DIY desktop featuring a significantly more powerful, true desktop-class graphics card that will easily outpace mobile silicon and offer a completely open upgrade path down the road.

It is an expensive niche, but if you value physical space above all else and want a machine that runs quiet, the GR70 delivers exactly what it promises.
