NUMA NUMA make Raspberry Pi go ZOOMA
The Raspberry Pi 5's performance is hindered by its memory architecture and controller, despite recent kernel patches boosting its speed.
MAIN POINTS FROM TRANSCRIPT
- Raspberry Pi 5's multi-core performance is only twice as fast as single-core, unlike competitors' 4x multiplier.
- Competitors use multiple memory chips, enhancing access speed, while Pi 5 uses a single chip.
- Recent patches and kernel tweaks have improved Pi 5's performance by up to 18%.
TAKEAWAYS
- The Pi 5's memory controller may be limiting its performance.
- Multi-core performance issues persist despite high-speed LPDDR4X memory.
- Kernel updates can significantly enhance the Pi 5's efficiency.
