The CHUWI AuBox X 256V packs a Core Ultra 7 processor, integrated Arc 140V graphics, 1TB of storage and a broad selection of connections into a 0.67-liter, 580-gram chassis. Its defining drawback is the 16GB of on-package memory: it cannot be upgraded. That makes this a compelling compact PC for buyers whose workloads fit within 16GB, but a poor bet for anyone who expects to need more memory later.
What the CHUWI AuBox X 256V offers
The AuBox X 256V is the Core Ultra 7 configuration of CHUWI’s AuBox X mini PC line. Its Intel Core Ultra 7 256V is an eight-core, eight-thread Lunar Lake processor with integrated Intel Arc 140V graphics; there is no separate desktop graphics card. CHUWI lists turbo speeds up to 4.8GHz and a configurable 8–37W TDP. The reviewed configuration combines the processor with 16GB LPDDR5X-8533 memory and a 1TB PCIe 4.0 SSD. CHUWI’s product page and Windows Central’s review list these specifications.
At 0.67L and 580g, it is designed to take up little desk space and is easy to move. CHUWI advertises support for up to three simultaneous displays and output up to 8K. The listed connections include USB4, USB-A, two HDMI 2.1 ports, DisplayPort 1.4 and 2.5Gb Ethernet, along with Wi-Fi 6E and Bluetooth 5.4. The actual resolution and refresh rate depend on the port, monitor and system configuration, so check the requirements for the displays you plan to use.
Can you upgrade the AuBox X’s RAM?
No. The 16GB LPDDR5X memory is on-package and not user-upgradeable. Windows Central and TechRadar both flag the fixed 16GB limit as a key buying consideration. TechRadar’s review also identifies 16GB as the maximum.

That ceiling matters more than the processor’s headline specifications if you regularly run many demanding applications, work with memory-intensive creative projects or want to experiment with local AI models. Some tasks may work well, but memory needs vary by software, model and workload. A high TOPS figure does not remove the system’s memory limit, and an external GPU would not add system RAM.
Storage is a separate upgrade question
Windows Central describes the installed SSD as upgradeable, and CHUWI promotes storage expansion. However, CHUWI’s blog discusses dual M.2 slots and PCIe 5.0 capability, while its current product listing specifies a 1TB PCIe 4.0 drive. Because those materials are not perfectly consistent about slot layout and revisions, confirm the configuration for the specific unit—using its current manual or seller details—before buying an expansion drive. CHUWI’s AuBox X blog post discusses the slots and PCIe 5.0.

Performance and AI claims: what they do and do not tell you
The Core Ultra 7 256V and Arc 140V may suit everyday productivity, media playback, light creative work and selected local AI tasks. That is a description of the platform’s potential, not a guarantee for every application or game. Performance depends on the workload, software and operating conditions. Windows Central’s reviewer reported strong general and local AI performance after using the unit for several weeks, but that is the publication’s assessment rather than independent testing by this article’s author.
CHUWI advertises up to 115 TOPS of combined CPU, GPU and NPU performance, including 47 NPU TOPS, for the 256V. These are manufacturer specifications, not application benchmarks. TOPS alone cannot show how quickly a particular AI model or software workflow will run: software support, workload design and available memory also matter. For comparison, CHUWI’s announcement lists up to 97 aggregate TOPS and 40 NPU TOPS for the Core Ultra 5 226V configuration. CHUWI’s announcement gives those 226V figures.

CHUWI’s product page also displays a PassMark score of 19,547, while noting that cross-platform benchmark comparisons are for reference and actual performance varies with workload and thermal conditions. It is a figure displayed by the manufacturer, not an independent test result for the reviewed unit. CHUWI’s product materials include that qualification.
Ports, monitors and external graphics
The port selection is a practical strength on paper: USB4, several USB-A connections, two HDMI 2.1 ports, DisplayPort 1.4 and 2.5Gb Ethernet are listed, alongside Wi-Fi 6E and Bluetooth 5.4. CHUWI advertises three-display support and output up to 8K, but those top-line claims do not specify every possible combination of resolution and refresh rate. Confirm that the available outputs and your monitors support the exact arrangement you need.

CHUWI and Windows Central list USB4, and CHUWI says the system supports an external GPU over USB4. An eGPU setup requires a compatible enclosure and graphics card, and no particular enclosure-and-card combination is established here. It is an optional route for a genuine graphics-performance need, not a fix for the fixed 16GB of system memory.

The 226V is the lower processor configuration, generally paired with 512GB of storage; the 256V adds the Core Ultra 7 256V and is listed with 1TB in the reviewed configuration. Both configurations have a 16GB memory ceiling in the cited official materials and review coverage. The 256V therefore does not solve the line’s main flexibility limitation.

| Configuration | Processor and graphics | Memory ceiling | Listed storage | Documented price context |
|---|---|---|---|---|
| AuBox X 226V | Intel Core Ultra 5 226V; integrated graphics | 16GB | Generally paired with 512GB | Windows Central reported $679 including tax at publication on June 15, 2026, for a 16GB/512GB configuration. This is a historical US review price, not a current quote. |
| AuBox X 256V | Intel Core Ultra 7 256V; integrated Intel Arc 140V graphics | 16GB | 1TB PCIe 4.0 in the reviewed configuration | CHUWI Global Store displayed $739 for the 256V/1TB option when accessed October 7, 2026. Windows Central reported $829 including tax for its reviewed 256V/1TB configuration on June 15, 2026; that is a historical US review price. |
The 226V’s lower processor tier and usual 512GB pairing may be enough if they suit your actual workload and budget. Compare the configurations by processor and integrated graphics, storage, and the current price in your region—not by assuming the 256V has more upgrade flexibility. The cited prices differ by date and storefront; verify the listing, taxes and shipping before buying. CHUWI’s Global Store displayed its listed price on October 7, 2026. Windows Central’s prices were reported in its June 15, 2026 review.
Is the CHUWI AuBox X 256V worth buying?
It is worth considering if you want a very small PC with modern connectivity, integrated graphics, a 1TB SSD and a processor suited to ordinary productivity and selected more demanding tasks—and you are confident that 16GB of memory is enough for the machine’s useful life. It is a less suitable choice if your work routinely pushes past 16GB, you need to run memory-heavy local models, or you expect to upgrade RAM later.
Windows Central’s June 15, 2026 review reported that CHUWI had no input and had not seen the review before publication; the reviewer also described using the PC for several weeks. TechRadar’s May 27, 2026 review praised the compact platform while criticizing the fixed memory ceiling. TechRadar listed a US price of $829 at publication, but that is historical rather than a current price reference. TechRadar’s review gives its publication date and assessment.
- Good fit: A space-constrained desk, everyday work, media use and selected AI tasks that fit within 16GB.
- Think twice: Memory-intensive creative work, heavy multitasking or local AI use that could exceed the fixed memory capacity.
- Check before ordering: Current regional price, included configuration, display requirements and the specific SSD expansion layout.
OpenClaw is not pre-installed
CHUWI’s product page says OpenClaw is not pre-installed and requires manual setup. Treat that advertised use case as a software setup project, not a ready-to-use feature on first boot. CHUWI’s product page states this explicitly.
