“60美元游戏主机”——AMD BC-250 (2025年)
The "$60 Gaming PC" – AMD BC-250 (2025)

华擎 BC-250 是一款非传统的平价硬件发烧友项目。该主板最初是为加密货币挖矿服务器设计的,搭载了一颗经过二次利用的“筛选版” PlayStation 5 APU(含 6 个 Zen 2 CPU 核心和 24 个 RDNA 2 GPU 计算单元)。这些主板在二手市场的价格仅为 70 至 100 美元,因能够运行《赛博朋克 2077》等游戏,已成为 DIY 游戏主机的热门选择。 然而,BC-250 并非“即插即用”的解决方案。将其改造为一台功能齐全的游戏电脑需要大量的动手能力,包括: * **固件修改:** 刷入自定义 BIOS 以解锁芯片组设置并重新分配 16GB 的共享 GDDR6 内存。 * **散热改造:** 用 3D 打印的定制导风罩和标准 120mm 风扇替换原本噪音巨大的服务器式鼓风散热器。 * **软件设置:** 由于 Windows 对其支持有限,用户通常需要依赖基于 Arch 的 Linux 发行版(如 Manjaro)以获得稳定的驱动兼容性。 尽管需要一定的技术折腾,但对于那些乐于尝试非传统硬件的人来说,BC-250 提供了一种独特的入门级游戏体验。感兴趣的用户可以在 [GitHub](https://github.com/csabakecskemeti/amd_bc-250_how-to) 上找到详细的指南和资源库。

有关使用 AMD BC-250(一种最初为加密货币挖矿而设计的 PS5 缩减版 APU)组装“60 美元游戏 PC”的关联文章在 Hacker News 上引起了轰动。虽然该项目在技术上很有趣——用户指出有潜力解锁额外的 GPU 和 CPU 核心——但由于访问量过大,原始网站已经崩溃。 社区评论者警告说,“60 美元”的价格标签具有误导性;市场需求已将实际价格推高至接近 300 美元。此外,用户反映诈骗行为有所增加,不诚实的卖家挂出 3D 打印外壳或空机壳来欺骗寻找该硬件的买家。尽管热度很高,但该项目仍然只是一个小众爱好者的尝试,而非一种经济实惠的主流方案。

Ok it’s not exactly $60 but you can get the board itself for that amount of money on eBay if you’re lucky, but on average the price is around $70-$100 (as of November 2025) which is still very cheap considering you can play Cyberpunk 2077 on this.

The BC-250 began life not as a gaming board, but as part of a crypto-mining rig.

The “trick” behind it: the BC-250 uses a cut-down version of the APU from a PlayStation 5 (PS5) — a repurposed SoC (system-on-chip).
Specifically: many PS5 APUs that didn’t meet console spec (“binned” or “defective” for console use) got repurposed. Instead of being discarded, these chips were re-used for mining/higher-density hardware.
The original deployment: there was a rack-mount mining “server” build from ASRock that used 12 BC-250 cards, targeted at miners — sold as a “barebone” 4U server chassis.
As mainstream GPU mining lost favor, many BC-250 units started circulating second-hand — offering hardware enthusiasts an opportunity to experiment.
“BC-250 is basically a Playstation 5 chip that didn’t make the cut, and was released as a crypto-mining board.”

Key Specs & Hardware Details

From public teardowns, benchmarks, and community experiments, BC-250 hardware specs are roughly:

  • CPU: 6 × Zen 2 cores (12 threads) — a cut-down PS5 APU.
  • GPU / iGPU: RDNA 2 architecture, 24 Compute Units (CUs) — reduced from the 36 CUs of a full PS5 APU.
  • Memory: 16 GB GDDR6 memory shared between CPU and GPU — there are no DDR4/DDR5 slots in a typical BC-250 board.
  • I/O & connectivity: Even though it looks like a “GPU card,” it works as a single-board PC — includes DisplayPort, USB (2.0/3.0), Ethernet, M.2 NVMe slot (for storage), power header (8-pin PCIe), CMOS battery, and backplate I/O shield.

Performance benchmarks & real-world behavior

  • Earlier reports suggested some instability with drivers, but recent community patches and updated drivers have improved support.
  • Community tests showed surprising results: e.g. one test rig running BC-250 reportedly ran games like Cyberpunk 2077, GTA V, Counter-Strike 2, Hitman 3 — at playable framerates (not high-end, but enough for a budget build).
  • Given enough power (cooling + PSUs) and tuning (BIOS tweaks, Linux driver config), some people report a gaming experience “close to an entry-level modern GPU.”

Here’s my real life Cyberpunk 2077 Benchmark:

How can you achieve this?

You have to get your hands dirty to achieve this — it’s not an out-of-the-box setup. You’ll need to perform both hardware and firmware modifications. Additionally, if you want it to look like the image above, that requires even more work.

Cooling

The BC-250 comes with a server-style closed finstack. It’s possible to use a blower fan to cool it, and there are even 3D-printed case designs that keep the original heatsink untouched (you’ll find these in my how-to repo linked below).

However, for good cooling performance, you’ll need to modify the finstack and open it up. This allows you to use one or two 120 mm fans for proper airflow. Be aware that this is a destructive modification — I’ve explained one method for doing it in the how-to repository.

Additionally, I refreshed the thermal pads and thermal paste for optimal cooling performance.

The unified memory

The BC-250 has 16 GB of unified memory, but by default it’s split between the CPU and GPU—typically 8 GB/8 GB (or in some cases 4 GB/12 GB). To use the device for gaming, you need to modify this and force a 512 MB allocation as VRAM. This may sound counterintuitive, but remember that this is an APU, not a traditional CPU/GPU setup.

To change these settings, the BIOS must be flashed to a custom 3.00 BIOS version that unlocks the Chipset configuration menu. This used to require an EEPROM programmer—at least according to documentation from about a year ago. Fortunately, there is now a bootable BIOS Flasher image that can handle the job much more easily.

OS

You can install Windows, but because this isn’t typical hardware, you won’t have proper graphics drivers. Most users run Arch-based Linux distributions instead. I went with Manjaro Linux, which works flawlessly. The Linux version of Steam works out of the box.

Case

You can find multiple designs online. I looked for compact cases that also enclose the PSU. I’ve built two versions: one is an ultra-portable format, and the other is more like a mini-PC.

This requires 3D printing and some DIY with the PSU.
