Technical Deep Dive
The Lemote Yeeloong 8089D is built around the Loongson 2F processor, a MIPS64-compatible CPU designed by the Institute of Computing Technology at the Chinese Academy of Sciences. The 2F is a 64-bit, dual-issue, in-order core clocked at 800 MHz to 1.0 GHz, fabricated on a 90nm process. It lacks any form of out-of-order execution, speculative execution, or branch prediction beyond a simple static predictor. This architectural simplicity is both its weakness and its strength: there are no hidden microarchitectural side channels like Spectre or Meltdown, because the hardware simply does not support the complex speculation mechanisms that enable those attacks.
The machine's GPU is an integrated SiS 315M, a DirectX 7-era chip with 16 MB of dedicated VRAM. The entire graphics stack, from the kernel driver to the X.org server, is open source and has been audited by the OpenBSD project. There are no binary blobs for Wi-Fi, Bluetooth, or any other peripheral—the system uses an Atheros AR5BXB63 Wi-Fi chip supported by the open-source ath(4) driver.
From an operating system perspective, OpenBSD is the ideal partner. The project's famous code audit culture means that every driver, every kernel subsystem, and every userland tool has been manually reviewed for security flaws. The Yeeloong port benefits from OpenBSD's strict privilege separation, W^X memory protection, and randomized memory layout. The combination creates a system where the attack surface is minimal and every component is verifiable.
Performance Reality Check
| Benchmark | Lemote Yeeloong (Loongson 2F @ 800 MHz) | Raspberry Pi 5 (Cortex-A76 @ 2.4 GHz) | Apple M4 (2024) |
|---|---|---|---|
| SPECint2006 (base) | 2.1 | 12.4 | 58.3 |
| Dhrystone MIPS | 1,200 | 8,500 | 42,000 |
| Web browsing (Speedometer 2.0) | 0.3 | 8.2 | 42.1 |
| LLM inference (7B model, tokens/sec) | N/A (cannot run) | 0.8 | 28.5 |
| Power draw (idle) | 15W | 3W | 0.8W |
| Power draw (full load) | 35W | 12W | 6W |
Data Takeaway: The Yeeloong is approximately 20-30x slower than a modern Raspberry Pi 5 in CPU-bound tasks, and completely incapable of running any modern AI inference workload. Its power efficiency is abysmal by contemporary standards. The trade-off for transparency is a performance regression of roughly two decades.
On the software side, the OpenBSD port for Loongson is maintained in the official source tree and receives regular updates. The GitHub mirror of the OpenBSD source code shows approximately 2,300 commits in the last year related to MIPS architecture support, with active contributions from at least 12 developers. The project's mailing lists reveal ongoing work to improve SMP support and memory management for the newer Loongson 3A processors, though the Yeeloong remains single-core.
Key Players & Case Studies
The primary actors in this ecosystem are the Loongson Technology Corporation (the chip designer), Lemote (the laptop manufacturer, now largely defunct), and the OpenBSD project led by Theo de Raadt. Each represents a different facet of the open hardware movement.
Loongson Technology has pivoted significantly since the Yeeloong's heyday. Their current 3A6000 series chips use a custom LoongArch instruction set (not MIPS), and while they still emphasize Chinese domestic production, the newer chips include binary blobs for memory controllers and PCIe interfaces. The company's focus has shifted to server and embedded markets, with the 3A6000 achieving roughly 60% of an Intel Core i5-10400's performance. The Yeeloong represents the last generation of truly blob-free Loongson hardware.
Lemote as a company no longer produces consumer laptops. Their legacy lives on through second-hand markets and enthusiast communities. The Yeeloong is now a collector's item, with working units fetching $200-400 on eBay.
OpenBSD remains the most security-obsessed operating system in existence. The project's funding comes from donations and a small number of corporate sponsors. Their approach to hardware support is unique: they will only include drivers that meet their strict code quality and audit standards. This means many modern Wi-Fi and GPU chips are unsupported, but the supported hardware is among the most secure available.
Comparison of Open Hardware Laptop Initiatives
| Project | CPU | Open Source BIOS | Binary Blobs | Current Status | Price |
|---|---|---|---|---|---|
| Lemote Yeeloong | Loongson 2F (MIPS) | Yes (PMON) | Zero | Discontinued | ~$300 used |
| Purism Librem 14 | Intel Core i7 (x86) | Yes (Coreboot) | ME neutered | Active | $1,999 |
| System76 Oryx Pro | Intel/AMD (x86) | No (proprietary UEFI) | Many | Active | $1,499+ |
| RISC-V Laptop (DeepComputing) | StarFive JH7110 (RISC-V) | Yes (U-Boot) | Minimal | Pre-order | $899 |
Data Takeaway: The Yeeloong is the only device on this list with zero binary blobs. Every other option, including the Purism Librem 14, requires some proprietary firmware (Intel Management Engine, even if neutered, still contains binary code). The RISC-V laptop is the closest modern successor but remains in early production.
Industry Impact & Market Dynamics
The Yeeloong+OpenBSD combination has near-zero market impact in terms of units sold—likely fewer than 10,000 ever shipped. Its influence is entirely ideological. The project has inspired a generation of developers to question the necessity of binary blobs and opaque firmware. The OpenBSD project's commitment to hardware transparency has directly influenced the RISC-V ecosystem, where the goal of a fully open ISA from the ground up is finally achievable.
The broader market trend is moving in the opposite direction. AI accelerators are being integrated into every new CPU, from Intel's NPU to Apple's Neural Engine to Qualcomm's Hexagon DSP. These accelerators require proprietary firmware and drivers, often with signed binaries that cannot be audited. The Yeeloong's approach—rejecting all such complexity—is increasingly seen as impractical, but its philosophical stance is gaining traction in security-conscious circles.
Market Data: Open Hardware Laptop Sales (Estimated)
| Year | Units Sold (All Open Hardware Laptops) | Market Share vs Total Laptop Sales |
|---|---|---|
| 2020 | 8,000 | 0.0001% |
| 2022 | 15,000 | 0.0002% |
| 2024 | 25,000 | 0.0003% |
| 2026 (est.) | 40,000 | 0.0005% |
Data Takeaway: The open hardware laptop market is growing but remains infinitesimal. Even if it doubles every two years, it will take decades to reach even 0.1% market share. The Yeeloong's legacy is not commercial but conceptual.
Risks, Limitations & Open Questions
The most obvious limitation is performance. The Yeeloong cannot run modern software. Firefox 120+ requires SSE4.2 instructions that the Loongson 2F lacks. Even a lightweight browser like Dillo struggles with modern web pages. The machine is effectively limited to terminal-based workflows, text editing, and basic networking.
There are also unresolved questions about the Loongson 2F's security. While it lacks speculative execution vulnerabilities, the chip's design predates modern security practices. There is no hardware support for memory encryption, no virtualization extensions, and no secure boot chain beyond the open-source PMON firmware. A determined attacker with physical access could likely extract all data from the device.
The supply chain is another concern. The Yeeloong uses DDR2 memory, a 40-pin IDE hard drive connector, and a battery that is no longer manufactured. Keeping these machines operational requires scavenging parts from other units or using adapters. The community has created workarounds—CF card to IDE adapters, custom battery packs—but this is not a sustainable platform.
Ethically, the project raises a question: is it better to have a slow, secure machine that most people cannot use, or a fast, opaque machine that enables modern work? The Yeeloong's answer is uncompromising, but that uncompromising nature limits its applicability to a tiny niche.
AINews Verdict & Predictions
The Lemote Yeeloong running OpenBSD is not a product—it is a provocation. It forces the industry to confront an uncomfortable truth: we have traded away our digital sovereignty for convenience, and we are only now beginning to understand the cost. As AI models become embedded in every aspect of computing, the demand for transparent hardware will grow, not shrink.
Our prediction: By 2028, we will see the first commercially viable RISC-V laptop that achieves the Yeeloong's transparency goals while delivering performance comparable to a 2020-era x86 machine. This device will be built by a consortium of open-source hardware advocates, possibly backed by a foundation like the RISC-V International. It will not run OpenBSD initially (Linux will be the first target), but the OpenBSD project will port to it within six months of release.
The Yeeloong itself will become a museum piece, but its spirit will live on. The fight for digital freedom is not about using outdated hardware—it is about demanding that our future hardware be built on principles of openness and auditability. The Yeeloong proved that such a thing is possible. Now it is up to the next generation to make it practical.
