The $75 AI Computer: How Shenzhen’s Board Makers Undercut NVIDIA — and What the Price Gap Really Buys

75美元的AI电脑：深圳板卡厂商如何击败英伟达——以及价格差距背后的真相

Originally published on RoboKrunch — teardowns, street prices, and BOM math from China’s edge-AI hardware scene. Two product launches, two weeks apart, tell you everything about where entry-level edge AI is heading. 本文最初发布于 RoboKrunch，涵盖了中国边缘AI硬件领域的拆解、市场价格及物料清单（BOM）分析。两周内相继发布的两款产品，揭示了入门级边缘AI的发展方向。

In late August 2026, NVIDIA announced the Jetson Orin Nano 2: 78 TOPS of AI compute, 8GB of memory, an 8-core Arm CPU, twice the inference performance of its predecessor — or the same performance at 40% less power. Impressive. Also: not shipping until the first half of 2027, with no price announced. 2026年8月下旬，英伟达发布了 Jetson Orin Nano 2：具备78 TOPS的AI算力、8GB内存、8核Arm CPU，推理性能是前代产品的两倍，或者在保持相同性能的情况下功耗降低了40%。令人印象深刻。但问题是：该产品要到2027年上半年才发货，且未公布价格。

Days later, Orange Pi opened orders for the Orange Pi 5 Max: a Rockchip RK3588 board with a 6-TOPS NPU, four lanes of PCIe Gen 3, Wi-Fi 6E, and up to 16GB of LPDDR5 — starting at $75 on AliExpress. You can buy it today. One costs less than a dinner out. The other doesn’t exist yet. 几天后，香橙派（Orange Pi）开启了 Orange Pi 5 Max 的预订：这是一款搭载瑞芯微（Rockchip）RK3588芯片的开发板，拥有6 TOPS的NPU、四通道PCIe Gen 3、Wi-Fi 6E以及最高16GB的LPDDR5内存，起售价仅为75美元，且在速卖通（AliExpress）上即可下单。前者价格甚至低于一顿晚餐，而后者目前还不存在。

This is the state of the entry-level edge AI market in September 2026: split in two, with a price gap so wide it demands an explanation. This article is that explanation. 这就是2026年9月入门级边缘AI市场的现状：市场一分为二，价格差距之大令人费解。本文旨在对此进行解读。

A few honest caveats before anyone screenshots this table: TOPS are not fungible. NVIDIA’s 40 TOPS are sparse INT8; Hailo’s 26 are dense INT8; Rockchip’s 6 are INT8 on a different NPU architecture. Divide-by-TOPS math across vendors is directionally useful and precisely wrong. Treat it as a price-of-admission indicator, not a benchmark. 在任何人截图此表格前，有几点诚恳的提示：TOPS（每秒万亿次运算）并非完全等同。英伟达的40 TOPS是稀疏INT8，Hailo的26 TOPS是稠密INT8，而瑞芯微的6 TOPS则是基于不同NPU架构的INT8。跨厂商进行TOPS除法计算仅具方向性参考意义，并不精确。请将其视为“入场券”价格指标，而非性能基准。

The Orin Nano’s 2026 street price is a mess. Newark lists the 8GB module between $577 and $802; China’s gray channels go as low as ~$369; element14 has delisted it in multiple regions. The $299 MSRP is from 2022 and increasingly theoretical. 2026年 Orin Nano 的市场价格非常混乱。Newark 上的8GB模块售价在577美元至802美元之间；中国灰色渠道价格低至约369美元；element14已在多个地区将其下架。299美元的建议零售价（MSRP）源自2022年，如今已越来越流于理论。

Board prices ≠ chip prices. The $75 buys you a complete single-board computer — SoC, RAM, PCB, ports, power circuitry. Keep that in mind, because it’s the whole story. The raw ratio: a usable RK3588 AI board costs roughly one quarter of NVIDIA’s entry-level list price, and roughly one fifth of what you’d actually pay for an Orin Nano module today. 板卡价格不等于芯片价格。75美元买到的是一台完整的单板计算机——包含SoC、内存、PCB、接口和电源电路。请记住这一点，因为这正是问题的核心。简单对比：一块可用的RK3588 AI开发板价格大约是英伟达入门级标价的四分之一，大约是你今天实际购买 Orin Nano 模块价格的五分之一。

How? Reason 1: The SoC business model is completely different

为什么？原因一：SoC商业模式完全不同

Rockchip has been designing ARM SoCs since 2001. It came up the hard way: MP3 players, then the white-box tablet wars of the early 2010s. That history is the business model: amortize R&D across enormous consumer volumes, then sell the same silicon into new markets nearly for free. 瑞芯微自2001年起就开始设计ARM SoC。它走的是一条艰辛的道路：从MP3播放器起家，随后经历了2010年代初的白牌平板电脑大战。这段历史构成了其商业模式：通过巨大的消费级出货量摊销研发成本，然后将同样的芯片以极低成本销往新市场。

The RK3588 was designed for a world of Android tablets, TV boxes, and digital signage. Edge AI developers are, from Rockchip’s perspective, a bonus market riding on R&D that tablets already paid for. The NPU that runs your YOLO model is the same NPU that was going to upscale video on a set-top box. RK3588最初是为安卓平板、电视盒子和数字标牌市场设计的。从瑞芯微的角度来看，边缘AI开发者只是一个“赠品市场”，其研发成本早已由平板电脑业务覆盖。运行你YOLO模型的NPU，和机顶盒里用于视频超分的NPU是同一个。

NVIDIA’s Jetson line works in reverse. The Orin Nano’s silicon descends from a data-center GPU architecture, and its R&D is amortized across a robotics and edge market measured in hundreds of thousands of units, not tens of millions — carrying the margin expectations of a company whose data-center GPUs command 70%+ gross margins. 英伟达的 Jetson 系列则完全相反。Orin Nano 的芯片源自数据中心GPU架构，其研发成本是在数十万台（而非数千万台）的机器人和边缘市场中摊销的，这背负着一家数据中心GPU毛利率高达70%以上的公司的利润预期。

Reason 2: Shenzhen makes the board for pocket change

原因二：深圳制造的成本优势

The SoC is maybe a third of the story. The rest is the most boring and most important sentence in hardware: Shenzhen exists. Orange Pi, Radxa, Firefly, Banana Pi — the RK3588 board ecosystem is a cluster of Shenzhen companies sitting within a one-hour drive of the world’s densest PCB fabrication, SMT assembly, and component distribution network. SoC可能只占故事的三分之一。剩下的部分可以用硬件领域最枯燥但也最重要的一句话来概括：深圳的存在。香橙派、Radxa、Firefly、Banana Pi——RK3588板卡生态系统是由一群深圳公司组成的，它们距离全球最密集的PCB制造、SMT贴片和元器件分销网络仅一小时车程。

Three structural consequences: 这带来了三个结构性结果：

1. No distributor margin stack. Orange Pi sells direct on AliExpress and Amazon. The traditional chain — manufacturer → regional distributor → local reseller — collapses to nearly zero. That alone is 20–30% off the price.

2. 没有分销商加价。 香橙派直接在速卖通和亚马逊上销售。传统的“制造商→区域分销商→本地经销商”链条几乎被压缩为零。仅此一项就节省了20-30%的成本。

3. No-frills productization. The $75 board has no fancy enclosure, no printed manual, no enterprise support contract. You’re buying the PCB and the silicon; the packaging is a static bag.

4. 极简产品化。 75美元的板卡没有精美的外壳、没有印刷手册、没有企业级支持合同。你买的就是PCB和芯片，包装就是一个防静电袋。

5. Volume across SKUs. The same RK3588 that goes into a $75 SBC also ships in TV boxes and industrial HMI panels by the millions. Board vendors aren’t betting the company on developers — developers are incremental margin.

6. 多SKU带来的规模效应。 用于75美元单板计算机的同一款RK3588芯片，也大量出货于电视盒子和工业HMI面板。板卡厂商并非将公司命运押注在开发者身上——开发者只是增量利润。
