TL;DR: The Raspberry Pi 5 delivers roughly 2–3x the CPU performance of the Pi 4 thanks to its quad-core Cortex-A76 chip, making it a true desktop-class upgrade for most workloads. However, the Pi 4 remains a compelling budget option for lighter projects where its lower power draw and mature ecosystem still shine.
What’s New Under the Hood
The Raspberry Pi 5, launched in late 2023, marked the biggest generational leap since the original Pi 4 in 2019. It swaps the Cortex-A72 cores for quad Cortex-A76 cores clocked at 2.4GHz, paired with the new BCM2712 chipset and a dedicated southbridge (RP1) that handles USB and Ethernet I/O separately. Memory options span 4GB, 8GB, and now 16GB LPDDR4X. The Pi 4, by contrast, tops out at 8GB and runs its A72 cores at 1.5GHz.

Real-World Benchmark Results
In synthetic tests like Geekbench 6, the Pi 5 scores roughly 2.5x the Pi 4 in single-core and multi-core workloads. Compiling a mid-sized C++ project that takes 12 minutes on a Pi 4 finishes in under 5 minutes on a Pi 5. Web browsing with Chromium feels genuinely responsive on the Pi 5, while the Pi 4 stutters with multiple tabs.
Storage tells a similar story: the Pi 5’s PCIe 2.0 lane (via an optional HAT) enables NVMe SSDs hitting 800MB/s, versus the Pi 4’s USB 3.0 ceiling of around 350MB/s. AI and machine learning tasks benefit too—the Pi 5’s improved NEON instructions and optional AI Kit push inference speeds well beyond the Pi 4.
Industry Impact
The Pi 5 has accelerated adoption in edge computing, robotics, and lightweight server deployments. Its power efficiency per watt of compute makes it attractive for industrial IoT. Meanwhile, the Pi 4’s price drop keeps it relevant for education and hobbyist markets.
FAQ
Q: Is the Raspberry Pi 5 worth upgrading from a Pi 4?
A: Yes, if you run desktop apps, compile code, or need fast storage. For simple GPIO or media projects, the Pi 4 is still sufficient.
Q: Does the Pi 5 use more power than the Pi 4?
A: Yes—it requires a 5V/5A USB-C supply (27W) versus the Pi 4’s 15W, though idle consumption remains similar.
Q: Can I use my old Pi 4 accessories with the Pi 5?
A: Most HATs work, but the new layout, USB-C power requirement, and PCIe connector mean some cases and power supplies need replacing.
