Specifications Comparison: Pi 5 vs Pi 4 Side by Side
Before getting into subjective opinions, here are the raw numbers. The Raspberry Pi 5 uses a Broadcom BCM2712 SoC with a quad-core Arm Cortex-A76 processor clocked at 2.4 GHz. The Pi 4 uses the BCM2711 with quad-core Cortex-A72 cores at 1.8 GHz. That alone represents a generational jump in ARM architecture — the A76 cores offer substantially higher instructions-per-clock compared to A72.
| Feature | Raspberry Pi 5 | Raspberry Pi 4 |
|---|---|---|
| CPU | Cortex-A76, 2.4 GHz | Cortex-A72, 1.8 GHz |
| GPU | VideoCore VII | VideoCore VI |
| RAM Options | 2GB, 4GB, 8GB, 16GB | 1GB, 2GB, 4GB, 8GB |
| PCIe | PCIe 2.0 x1 (via FFC) | None |
| USB 3.0 | 2x USB 3.0 (5 Gbps) | 2x USB 3.0 (shared bus) |
| Display | 2x micro-HDMI (4Kp60) | 2x micro-HDMI (4Kp30 dual) |
| Camera/Display | 2x 4-lane MIPI (22-pin) | 1x CSI, 1x DSI (15-pin) |
| Power | USB-C PD, 5V/5A recommended | USB-C, 5V/3A |
| RTC | Yes (external battery) | No |
| Power Button | Yes (built-in) | No |
The Pi 5 also features the new RP1 southbridge chip, which handles I/O operations independently from the main SoC. This means GPIO, SPI, I2C, UART, and USB operations no longer compete with the CPU for bandwidth — a meaningful improvement for I/O-intensive projects.
Performance Benchmarks and Real-World Speed
In synthetic benchmarks, the Raspberry Pi 5 delivers roughly 2-3x the performance of the Pi 4 in multi-threaded workloads. Single-threaded performance sees approximately a 2x improvement thanks to the architectural upgrade from Cortex-A72 to Cortex-A76.
For practical tasks, here is what this translates to:
- Web browsing (Chromium): Pages load noticeably faster. Heavy JavaScript sites that stuttered on the Pi 4 run smoothly on the Pi 5. Tab switching with 5+ tabs open is practical on the Pi 5 but painful on the Pi 4.
- Compilation (building a kernel): A Linux kernel compile that takes around 90 minutes on the Pi 4 finishes in roughly 35-40 minutes on the Pi 5.
- Python scripts: CPU-bound Python workloads run approximately 2x faster. I/O-bound scripts benefit less, though the faster storage interface helps.
- Video playback: The VideoCore VII GPU handles 4Kp60 HEVC without issue. The Pi 4 maxes out at 4Kp30 for dual display setups.
- Docker containers: Starting and running multiple containers is significantly snappier, making the Pi 5 a more viable home lab platform.
The biggest performance gain comes from pairing the Pi 5 with NVMe storage via the PCIe interface. SD card read speeds max out around 100 MB/s, while an NVMe drive through a HAT adapter can deliver 800+ MB/s sequential reads. This transforms the boot and application loading experience.
Connectivity and Peripheral Upgrades
The Pi 5 addresses several connectivity pain points that Pi 4 users have dealt with for years.
PCIe 2.0: This is the headline new feature. The single-lane PCIe 2.0 interface (accessible via a compact FFC connector) opens the door to NVMe storage, additional networking, and other PCIe peripherals. While PCIe 2.0 x1 offers a theoretical maximum of 500 MB/s, it is still dramatically faster than USB 3.0 for storage.
USB 3.0: Both boards have 2x USB 3.0 ports, but the Pi 5’s USB 3.0 ports are wired through the RP1 chip with dedicated bandwidth. On the Pi 4, the USB 3.0 and Ethernet shared a single PCIe lane through VIA VL805, creating contention. The Pi 5 eliminates this bottleneck.
Dual Camera Support: The Pi 5 has two 4-lane MIPI transceiver interfaces using the new 22-pin FFC connectors. You can connect two cameras simultaneously — useful for stereo vision, dashcam setups, or security systems. Note that Pi 4 camera cables (15-pin) are not compatible; you need the 22-pin cables for the Pi 5.
Bluetooth and Wi-Fi: Both use dual-band 802.11ac Wi-Fi and Bluetooth 5.0. The Pi 5 uses the same Infineon chip but with improved antenna performance. In practice, Wi-Fi speeds are comparable, though the Pi 5 shows marginally better Bluetooth range.
Real-Time Clock: The Pi 5 includes an on-board RTC with a connector for a small lithium coin cell battery. This means the Pi 5 can keep time when powered off — essential for data logging, scheduling, and IoT applications where network time may not be available at boot.
Power Requirements and Thermal Management
The Pi 5 demands more power than the Pi 4. The official recommendation is a 5V/5A USB-C power supply (with USB PD negotiation), compared to the Pi 4’s 5V/3A requirement. Using an underpowered supply on the Pi 5 triggers throttling warnings and limits USB peripheral power delivery.
In India, this means your existing Pi 4 power supply will not reliably power a Pi 5 — especially with USB peripherals attached. Budget for a proper 27W USB-C PD power supply.
Thermally, the Pi 5 runs hotter due to higher clock speeds and the more powerful CPU. Under sustained load, the bare Pi 5 will thermal-throttle without active cooling. The official Raspberry Pi Active Cooler (a combination heatsink and fan that connects to a dedicated 4-pin header on the Pi 5) is practically a requirement for sustained workloads.
The Pi 4, while not cool by any means, can get by with passive heatsinks for most use cases. Only sustained compilation or video encoding pushes it to throttling temperatures without a fan.
For Indian conditions — where ambient temperatures routinely hit 35-45°C in summer — active cooling on the Pi 5 is non-negotiable for reliable operation. A good aluminium case with built-in fan solves both thermal and dust concerns.
Pricing in India and Value Analysis
As of 2026, Raspberry Pi pricing in India reflects both the official foundation pricing and import/GST considerations:
- Raspberry Pi 5 (2GB): Approximately ₹4,500 – ₹5,000
- Raspberry Pi 5 (4GB): Approximately ₹6,500 – ₹7,500
- Raspberry Pi 5 (8GB): Approximately ₹8,500 – ₹9,500
- Raspberry Pi 5 (16GB): Approximately ₹12,000 – ₹13,500
- Raspberry Pi 4 (4GB): Approximately ₹5,500 – ₹6,500
- Raspberry Pi 4 (8GB): Approximately ₹7,500 – ₹8,500
The price gap between a Pi 4 4GB and Pi 5 4GB is roughly ₹1,000-1,500. Given the substantial performance and feature improvements, the Pi 5 is the better value for new purchases. The Pi 4 still makes sense when you find it at a steep discount or when your project explicitly requires its form factor or accessory ecosystem.
Factor in the total cost of ownership: the Pi 5 needs a better power supply (add ₹800-1,200) and active cooling (add ₹500-1,500). An NVMe HAT adapter and SSD add another ₹2,000-4,000 but deliver a transformative performance improvement.
Software and Accessory Compatibility
The Pi 5 runs Raspberry Pi OS (based on Debian Bookworm) and supports the same software ecosystem as the Pi 4. Most applications, Docker containers, and programming environments work identically on both boards.
However, there are compatibility considerations:
- GPIO HATs: The 40-pin GPIO header is identical between the Pi 4 and Pi 5. Most HATs work without modification. However, HATs that use low-level DMA or direct register access may need driver updates for the RP1 chip.
- Camera cables: The Pi 5 uses 22-pin FFC camera connectors instead of the Pi 4’s 15-pin connectors. You need new cables, though the camera modules themselves are compatible.
- Cases: Pi 4 cases do not fit the Pi 5. The board dimensions are similar, but the port layout, connector positions, and the new PCIe connector mean you need Pi 5-specific cases.
- Power supplies: The Pi 5 requires USB-C PD at 5V/5A for full functionality. Pi 4 power supplies (5V/3A) will work but may cause throttling.
- Displays: HDMI and DSI displays work on both. The Pi 5 supports dual 4Kp60 output, while the Pi 4 is limited to 4Kp30 on dual displays.
For software, RetroPie, Home Assistant, Pi-hole, OctoPrint, Kodi, and other popular distributions all support the Pi 5 with their latest releases. Python, Node.js, Docker, and Kubernetes work without issues.
Who Should Upgrade and Who Should Stay
Upgrade to Pi 5 if:
- You use the Pi as a desktop replacement — the performance difference is dramatic.
- You run multiple Docker containers or a home lab setup — more RAM and CPU power helps.
- You want NVMe storage — only the Pi 5 has PCIe.
- You need dual cameras — stereo vision, dashcams, or multi-angle security.
- You are building a new project from scratch — the Pi 5 is better value per rupee spent.
- You want an RTC for offline timekeeping.
Stick with Pi 4 if:
- Your current project works fine — no reason to fix what is not broken.
- You have invested heavily in Pi 4 cases and accessories.
- Power availability is limited — the Pi 4 runs on simpler power supplies.
- You are running a headless server that is not CPU-bound (Pi-hole, basic NAS).
- Budget is extremely tight and you can find the Pi 4 at a significant discount.
Frequently Asked Questions
Can I use my Pi 4 SD card in a Pi 5?
Not directly. The Pi 5 requires Raspberry Pi OS Bookworm or later with Pi 5-specific firmware. You will need to flash a fresh image. Your data and configurations can be migrated manually.
Is the Raspberry Pi 5 available in India?
Yes. The Raspberry Pi 5 is available through authorised distributors in India, including Zbotic. Stock availability has stabilised since the initial launch, and all RAM variants (2GB, 4GB, 8GB, 16GB) are available.
Does the Pi 5 support PoE (Power over Ethernet)?
Yes, with a compatible PoE HAT. The Pi 5 uses a different PoE header than the Pi 4, so you need a Pi 5-specific PoE HAT. Waveshare and the Raspberry Pi Foundation both offer compatible options.
Can I overclock the Raspberry Pi 5?
Yes. The Pi 5 can be overclocked to 2.8-3.0 GHz with adequate cooling. Add arm_freq=2800 to /boot/firmware/config.txt. Active cooling is mandatory when overclocking, and stability varies by individual chip.
Which is better for a media centre — Pi 4 or Pi 5?
The Pi 5 is better due to its faster CPU (smoother Kodi navigation), better GPU (4Kp60 dual display), and PCIe for NVMe storage (faster library scanning). However, the Pi 4 is perfectly adequate for 1080p media playback.
What happened to the 1GB Pi 4 variant?
The 1GB Pi 4 was discontinued. The Pi 5 starts at 2GB, and for most projects, the 4GB variant is the recommended minimum.
Conclusion
The Raspberry Pi 5 is a genuine generational upgrade over the Pi 4 — not a minor revision. The 2-3x CPU performance improvement, PCIe support, dedicated I/O chip, dual camera interfaces, and built-in RTC make it the clear choice for new projects in 2026. The price premium over the Pi 4 is modest enough that it does not justify buying the older board unless you have a specific reason.
If you are building something new, start with the Pi 5. If your existing Pi 4 project is working well, there is no urgency to upgrade — but when you do expand or rebuild, the Pi 5 should be your next board.
