TL;DR: The Raspberry Pi 5 is the better buy for most users, thanks to its 2–3x CPU/GPU performance boost, PCIe support, and real-time clock. Only choose the Pi 4 if you find it at a steep discount or need its lower power draw for always-on, lightweight tasks.
What Changed Since Launch
Since its late-2023 debut, the Raspberry Pi 5 has matured considerably. Firmware updates have improved power efficiency and thermal behavior, while the 2GB variant, introduced in 2024 at a lower price point, made the flagship architecture more accessible. The Pi 4, meanwhile, remains in production and has seen its price fluctuate with memory costs, but its role has shifted from “default choice” to “budget alternative.”

Specs That Matter
The Pi 5 runs a 2.4GHz quad-core Cortex-A76 CPU versus the Pi 4’s 1.5GHz Cortex-A72 — roughly two to three times faster in real-world workloads. Graphics jump from VideoCore VI to VideoCore VII, doubling GPU throughput and finally delivering smooth dual 4K60 display output. The Pi 5 adds a PCIe 2.0 lane for NVMe SSDs, a dedicated power button, and a real-time clock, all absent on the Pi 4. It also swaps micro-USB power for USB-C PD and introduces the RP1 I/O controller, which unlocks higher USB bandwidth. The trade-off: the Pi 5 draws more power and runs hotter, effectively requiring active cooling under sustained load.
Industry Impact
The Pi 5 pushed single-board computers closer to entry-level desktop territory, pressuring competitors like Orange Pi and Rock Pi to match its I/O and ecosystem. More importantly, PCIe and the RP1 chip signaled that Raspberry Pi intends to support edge AI, NAS builds, and industrial applications directly, rather than leaving those niches to x86 mini-PCs.
Verdict
For new projects — media centers, home servers, retro gaming, robotics — the Pi 5’s speed and expandability justify the modest premium. The Pi 4 still makes sense for simple, low-power, always-on jobs where its cheaper price and cooler operation win out.
FAQ
Q: Is the Raspberry Pi 5 worth the extra cost over the Pi 4?
A: Yes, for most users. The performance, PCIe, and I/O upgrades deliver far more value than the price difference, especially for anything beyond basic scripting.
Q: Can I use my existing Pi 4 accessories with the Pi 5?
A: Mostly yes — HATs, cases, and displays generally fit, though the Pi 5 needs a USB-C PD power supply and often active cooling, so some older kits require upgrades.
Q: Does the Pi 5 run hotter than the Pi 4?
A: It does. The faster chip and higher power draw mean a heatsink or fan is strongly recommended for sustained workloads, whereas the Pi 4 often ran fine passively.
