I prefer RISC as a CPU architecture over CISC. RISC is a simpler design that should deliver more CPU performance with fewer transistors and is more power-efficient. We have to recognize that Intel and AMD have made great progress in increasing the performance and efficiency of the x86 CISC architecture.
But the x86 architecture comes with a FreeDOM cost, Intel has the Intel Management Engine and closed Proprietary software is required to initialize the components. The same can be said about AMD; AMD has the AMD Platform Security Processor and binary blobs are required.
Power is currently the most powerful alternative that doesn’t require binary blobs; this is not only great for free/open source activists. A truly open-source firmware that can be reviewed / audited is also for nice security reasons.
For these reasons; I support the PowerPC notebook initiative: https://www.powerpc-notebook.org. This project tries to design an open-hardware PowerPC notebook, the schematics are already completed and available at GitLab: https://gitlab.com/power-progress-community/oshw-powerpc-notebook/powerpc-laptop-mobo.
There is a donation campaign running by the project to complete the PCB design at: https://www.powerpc-notebook.org/campaigns/donation-campaign-for-pcb-design-of-the-powerpc-notebook-motherboard/.
If this project interest you, you might consider donating to it.
