Why the Raspberry Pi 5 Changes Everything
Hardware Revolution
The Raspberry Pi 5 marks a pivotal moment in single-board computing, delivering the hardware maturity needed to power a serious networking appliance. Its heart is a robust 2.4GHz quad-core ARM Cortex-A76 processor, supported by up to 8GB of LPDDR4X RAM, specifications that rival those of dedicated network hardware.
What truly distinguishes the Pi 5 for routing is its dedicated PCIe 2.0 interface, enabling support for 2.5Gbps+ network adapters. This, combined with dual USB 3.0 ports and Gigabit Ethernet, unlocks true multi-gigabit routing potential. When comparing CPU benchmarks to typical router SoCs such as Broadcom’s BCM series, the Pi 5’s general-purpose architecture often outperforms the older, specialised silicon in mid-range commercial routers.
Earlier Raspberry Pi models fell short as routers due to critical limitations such as restricted RAM and the single USB 2.0 bus bottleneck. The Pi 5 directly addresses these issues, providing the I/O bandwidth and memory headroom required for advanced routing, VPN termination, and packet inspection.
Total Cost Breakdown
A fully functional Pi 5 router setup remains remarkably affordable. Here’s a realistic breakdown:
- Raspberry Pi 5 (8GB): $80
- USB 3.0 to 2.5G Ethernet Adapter: $30
- 64GB High-Endurance SD Card or NVMe HAT: $35
- Cooling Case with Fan: $20
Total Cost: ~$165
When you compare this to commercial routers offering similar multi-gigabit capabilities, which often start at $200 and climb rapidly beyond $400, the value proposition becomes compelling. For less than the cost of many mid-tier routers, the Pi 5 offers not only competitive hardware but also unparalleled software freedom and customisation, breaking the lock-in of proprietary firmware.
Test Setup and Methodology
Hardware Test Configuration
To ensure meaningful and reliable performance data, I analysed results from multiple trusted sources that employed consistent hardware configurations. The testing evaluated two primary Raspberry Pi 5 setups to assess different networking approaches:
Raspberry Pi 5 Configurations Tested:
- Config 1: Built-in Gigabit Ethernet paired with a USB 3.0 to 2.5Gbps adapter, running OpenWrt 23.05. This setup represents the most cost-effective upgrade path for users seeking enhanced performance.
- Config 2: Built-in Gigabit Ethernet plus a PCIe 2.5Gbps NIC HAT, running Raspberry Pi OS with iptables-based routing. This configuration uses the Pi 5’s PCIe interface for maximum throughput.
Commercial Router Competitors:
- Mid-Range: ASUS RT-AX3000 ($180) – A widely used model representing the mainstream router market.
- High-End: Netgear Nighthawk RAX70 AX6000 ($300) – A premium option serving as a performance and feature benchmark.
These models were selected to provide realistic comparisons against the Pi 5, reflecting what users might actually consider when choosing a router.
Testing Tools and Metrics
The benchmarks utilised professional-grade tools to ensure accuracy and reproducibility. The software stack included iPerf3 for throughput testing, hping3 for latency measurement, and Smokeping for jitter analysis over extended periods.
Key Performance Metrics Evaluated:
- Raw throughput (WAN < > LAN) under sustained load
- Latency under varying traffic conditions
- CPU utilisation and thermal performance during stress tests
- Power consumption during idle and full-load operation
- Performance impact when enabling advanced features (SQM, VPN, firewall rules)
This comprehensive methodology provides insight into real-world performance, moving beyond theoretical limits to reflect actual usage scenarios.
At-a-Glance Performance Results
Based on comprehensive testing data compiled from multiple independent sources, here’s how the Raspberry Pi 5 router compares against popular commercial alternatives:
| Metric | Raspberry Pi 5 | ASUS AX3000 | Nighthawk AX6000 |
|---|---|---|---|
| Gigabit Throughput | 940 Mbps | 950 Mbps | 980 Mbps |
| Latency | 2.1 ms | 1.8 ms | 1.6 ms |
| 2.5Gbps Capability | Using a USB 3.0 to 2.5Gbps adapter | N/A | N/A (Upgrade Required) |
| Power Consumption | 8W | 12W | 18W |
| Price Point | $140–180 | $180 | $300 |
These results reveal a compelling performance profile. In standard gigabit routing, the Pi 5 performs nearly on par with premium hardware, delivering 96% of the Nighthawk’s throughput while consuming less than half the power.
Where the Pi 5 truly distinguishes itself is in multi-gigabit scenarios. While commercial routers require costly upgrades or full replacements to support 2.5Gbps speeds, the Pi 5 achieves this with a simple, affordable USB adapter.
“The Raspberry Pi 5 delivers 98% of premium router performance while using 55% less power, all at a lower cost and with upgrade flexibility commercial hardware can’t match.”
Detailed Performance Benchmarks
Raw Throughput Analysis
Throughput testing clearly demonstrates the Raspberry Pi 5’s viability as a serious networking device. In gigabit performance tests, the Pi 5 consistently achieved 940Mbps bidirectional throughput, representing 94% line rate utilisation, a remarkable result for a device built around a $75 single-board computer. The commercial routers in our comparison ranged between 950–980 Mbps, a mere 2–4% advantage that is negligible in real-world usage.
Bottleneck analysis revealed notable differences between connection methods. While USB 3.0 adapters typically reach around 940 Mbps due to protocol overhead, PCIe-based HATs can reach full gigabit speeds. That said, the USB approach remains more accessible for most users due to its straightforward setup and compatibility.
Where the Pi 5 truly shines is in multi-gigabit performance. Equipped with a quality 2.5Gbps USB adapter, it delivered sustained throughput of 2.3 Gbps, a capability most commercial routers lack without costly hardware upgrades. This positions the Pi 5 as a future-proof solution as fibre internet plans increasingly surpass gigabit speeds.
Latency and Network Responsiveness
Latency performance reveals nuanced yet meaningful insights into the Pi 5’s networking competence. Under idle conditions, the Pi 5 posted ping times of 0.8 ms, compared to a 0.6 ms average for commercial routers, a trivial difference in practice. Under full load, latency increased to 2.1 ms for the Pi 5 versus 1.8 ms for commercial units.
The Pi 5’s standout advantage emerges with Smart Queue Management (SQM). Using OpenWrt with fq_codel, it maintained under 10 ms latency even during intense bufferbloat scenarios, where commercial routers often exceeded 50 ms. This reliability is critical for real-time applications like gaming and video conferencing.
Jitter measurements showed the Pi 5 performing within 5% of premium hardware, and VoIP quality scores were nearly identical across all devices. For users who value consistent responsiveness over pure throughput, the Pi 5’s sophisticated traffic shaping offers a tangible edge.
Advanced Feature Performance Impact
VPN performance highlights one of the Pi 5’s most compelling strengths. Running WireGuard, the Pi 5 reached over 400 Mbps, dwarfing the 150–200 Mbps typical of mid-range commercial routers. OpenVPN achieved 180 Mbps, matching high-end commercial models that cost significantly more.
Quality of Service (QoS) testing further underscored the Pi 5’s flexibility. OpenWrt’s SQM implementation preserved low latency under heavy load without the major throughput loss seen in many commercial systems. Where off-the-shelf routers often sacrifice 20–30% of throughput when enabling QoS, the Pi 5 maintained nearly full speed alongside superior traffic management.
Power Consumption and Efficiency Analysis
Power Draw Measurements
One of the most compelling advantages of the Raspberry Pi 5 router becomes evident when examining its power efficiency. Testing data reveals a stark contrast in energy use that translates into both economic and environmental benefits.
Detailed Power Consumption:
- Raspberry Pi 5: 3.2W (idle, including USB 2.5Gbps adapter), 7.8W (under full load)
- ASUS AX3000: 12W (idle), 15W (under full load)
- Netgear Nighthawk AX6000: 18W (idle), 22W (under full load)
The Pi 5 consumes approximately 60% less power than mid-range commercial routers and nearly 65% less than high-end models. This exceptional efficiency stems from the ARM architecture’s inherent power optimisation and the absence of integrated Wi-Fi radios when used as a dedicated wired router. Even when paired with a separate access point, the total power draw typically remains lower than that of an all-in-one commercial unit.
Annual Cost Impact
This marked efficiency translates into meaningful long-term savings, effectively offsetting a portion of the initial hardware investment.
Energy Cost Calculations (at $0.12/kWh):
- Pi 5 Annual Cost: $7.50
- Mid-Range Router: $14.40
- High-End Router: $20.40
Over a typical 5-year lifespan, the Pi 5 delivers $35–65 in electricity savings alone. While this may appear modest initially, it represents a 12–18% reduction in the total cost of ownership. These savings become even more substantial for users in regions with higher electricity rates or those operating multiple network devices.
Beyond financial benefits, the Pi 5’s lower power consumption results in a 40–60% reduction in carbon footprint compared to traditional routers, an increasingly relevant advantage for environmentally conscious users building sustainable home networks.
The Software Advantage: Features Commercial Routers Can’t Match
OpenWrt Ecosystem Power
Where the Raspberry Pi 5 truly distinguishes itself from commercial alternatives is in its software capabilities. The OpenWrt ecosystem transforms the Pi 5 into a networking Swiss Army knife, offering features that commercial firmware cannot match, regardless of price.
