- ★ASRock’s BC-250 uses a PS5-derived SoC and can now be hacked to unlock all 40 GPU compute units.
- ★That gives it more compute units than a base PS5, but performance depends on much more than raw GPU blocks.
- ★The story matters most for enthusiasts trying to turn mining hardware into a low-cost Steam Machine.
ASRock’s BC-250 is the kind of hardware that was never meant to get a comfortable second life under a living-room TV. It is a server and mining-oriented board built around a PS5-derived SoC, aimed at a very different job than running games as a small console-like PC. That is why the new development is interesting: according to Tom’s Hardware, enthusiasts have found a third-party hack that unlocks all 40 GPU compute units inside the chip.
On paper, that puts the BC-250 above the base PlayStation 5, which is known for shipping with fewer active compute units. But that comparison needs a steady hand. A console is not just a count of CU blocks. Sony’s system has a closed software chain, tuned power delivery, a defined memory setup, a fixed thermal envelope and game engines targeting a predictable platform. The BC-250 is a different machine: mining-era hardware, PC-side compromises and an enthusiast workaround trying to extract more from unusual silicon.
The mining board with a PS5-derived SoC now has more GPU compute units on paper than a base PlayStation 5, but that does not automatically mean console-class performance.

That makes the story less “cheap PS5” and more “experimental Steam Machine.” If the BC-250 is being used for PC gaming, the natural software context becomes Steam and, depending on the build, the wider world of Linux or Windows drivers, compatibility layers and console-style usability gaps. The hack then runs into the less glamorous questions that matter most: whether drivers can reliably expose the full GPU, how much performance improves in actual games, how much power the board draws, how hard it is to cool, and whether the setup survives updates without constant hand repair.
The technical appeal is obvious. A board with a PS5-derived SoC and 40 unlocked compute units sounds like recovered value from the crypto-hardware aftermath: mining hardware redirected into gaming, where every extra GPU block looks like unused headroom. But hardware used outside its intended role rarely delivers a clean win. It needs firmware behavior, tools, documentation, stable profiles and proper measurements. Without those, the 40-CU figure is important, but not enough.
For TECH&SPACE, the useful signal is that gaming hardware is no longer moving only through official consoles, retail GPUs and polished mini-PCs. There is a growing gray zone between industrial leftovers, enthusiast BIOS-level work and software layers such as SteamOS. The BC-250 is not suddenly a mainstream product. It is a test case for how far a community can push console-adjacent silicon after it has been pulled out of its original business model and forced into a gaming role.
