TL;DR: The Raspberry Pi 5 delivers roughly two to three times the CPU performance of the Pi 4, thanks to its 2.4GHz quad-core Cortex-A76 processor and new southbridge architecture. Real-world benchmarks confirm it finally handles 4K video, light AI workloads, and desktop multitasking without the compromises that defined earlier models.
What Changed Under the Hood
The Raspberry Pi 5 marks the biggest architectural leap since the original Pi 4. At its heart sits a Broadcom BCM2712 quad-core Arm Cortex-A76 CPU clocked at 2.4GHz, paired with a VideoCore VII GPU. The headline addition is the RP1 I/O controller, a custom southbridge that offloads USB, Ethernet, and GPIO duties from the main SoC. This frees the CPU to focus on compute, and the benchmark numbers reflect it. The board also gains PCIe 2.0 via an FPC connector, enabling NVMe storage that transforms random read/write speeds compared to microSD.

Real-World Benchmark Results
In synthetic tests like Geekbench 6 and Sysbench, the Pi 5 posts single-core scores roughly 2.5 times higher than the Pi 4 and multi-core gains near 2x. But synthetic numbers only tell part of the story. In practical scenarios, the Pi 5 boots Raspberry Pi OS in about 12 seconds from NVMe versus 25 seconds on a Pi 4 with microSD. Video playback of 4Kp60 HEVC is now smooth, a task the Pi 4 struggled with. Compiling mid-sized software projects finishes in nearly half the time. Even light local AI inference, such as running a small object detection model, is feasible at a few frames per second.
Industry Impact and Availability
The Pi 5’s PCIe interface and improved thermals have made it a serious contender for edge computing, home servers, and industrial automation, segments previously dominated by x86 mini-PCs. Competitors like Orange Pi and Radxa have responded with aggressive spec bumps, heating up the single-board computer market. Demand remains strong, and the $60 (4GB) and $80 (8GB) price points keep it accessible. The active cooler is now recommended for sustained loads, a sign the Pi 5 finally trades passive silence for genuine desktop-class performance.
FAQ
Q: Is the Raspberry Pi 5 worth upgrading from a Pi 4?
A: Yes, if you need faster storage via NVMe, smooth 4K playback, or desktop-class responsiveness. For simple GPIO projects, a Pi 4 remains adequate.
Q: Does the Pi 5 require a new power supply?
A: Yes, it uses a 5V/5A USB-C supply with Power Delivery support to unlock full peripheral and CPU performance.
Q: Can the Pi 5 run AI workloads?
A: It handles light inference tasks like object detection and small language models, but heavy training still requires dedicated accelerators.
