IBM’s move puts Power on the same footing as RISC-V in terms of accessibility. It also gives RISC-V aficionados something new to think about. It doesn’t get any more blue-chip than that. Thirteen of the 500 fastest supercomputers in the world – and both of the top two – are based on IBM’s Power architecture. The good news is, hey, free processor! What’s not to like about that? You get an official IBM-designed CPU with a huge upside growth path. This is either really good news or really bad news, depending on your perspective. Starting now, you can design your own PowerPC processor without first paying a hefty license fee. It’s a no-cost, royalty-free license to the ISA much like the one for RISC-V and other open-source processors. IBM has released the Power Architecture instruction set to the Linux Foundation, making it freely available to anyone who wants it. “With great power comes great responsibility.” – Uncle Ben ![]()
