As you may know, the PI 5 is a fantastic improvement to our cherished Raspberry PI! The benchmarks below show how much our Raspi has improved across the board.
So, is the upgrading worthwhile? I gathered the benchmark results I could find online and I'll summarise the performance increase by comparing it to the PI 4 performance, using percentages to make the comparison of the two Raspberrys even easier.
Raspberry PI 5 specs versus PI 4
Here are some of the key improvements:
- Processor: The Pi5 features a 2.4GHz quad-core 64-bit Arm Cortex-A76 CPU, which is a significant upgrade over the 1.5 GHz quad-core ARM Cortex-A72 processor found in the Raspberry Pi 4. This processor provides up to three times the performance of the previous generation.
- GPU: The Raspberry Pi 5 GPU specs show a Videocore 7 microarchitecture clocked at 1GHz, vs a 500 MHz Videocore 6 on the Pi 4 Model B
- USB Ports: The Pi 5 features also two USB 3.0 ports but with simultaneous 5Gbps operation, instead of shared 4Gbps ports.
- Video Output: The Pi 5 is capable of driving two simultaneous 4Kp60 HDMI displays, where the PI4 was limited to 30 frames per second with two 4K displays
- Wireless connectivity: The Raspberry Pi 4 features built-in dual-band 802.11ac wireless networking. It also has Bluetooth 5.0 support, which allows for better range and speed than previous versions.
- Connectivity: a single lane PCI-E 2.0 connector is now paving the way for SSD expansion cards, and 2 × 4-lane MIPI camera/display transceivers are available
- Micro-SD: the max speed was increased with SDR104 mode support
Raspberry PI 5 CPU Performance comparison
The PI5 CPU upgrade to a quad core Cortex-A76 (BCM2711) is three microarchitectural generations beyond the old Cortex-A72, and gives an impressive boost as confirmed in benchmarks given by Gareth Halfacree and Jaryd. Below is the increase in percent over the previous generation Raspberry PI4B:
- Linpack Single Precision: +290%
- Linpack Double Precision: +260%
- Linpack Single Precision with NEON instructions: +290%
- Speedometer 2.1 browser speed test: +190%
- BZip2 File compression single threaded: +119%
- BZip2 File compression multi threaded: +99%
Raspberry PI 5 memory bandwidth
The upgraded 32-bit LPDDR4X SDRAM subsystem, runs now at 4267MT/s, up from an effective 2000MT/s on Raspberry Pi 4.
I'm waiting for Ramspeed and Passmark benchmark to confirm this theoretical doubling of memory bandwidth. Jaryd found a five time speed increase with Ramspeed, which is surprising, but could be explained by kernel-level optimization for this processor.
- RAMspeed 1MB blocks write: +560% to be confirmed
- RAMspeed 1MB blocks read: +373% to be confirmed
Raspberry PI 5 Networking improvements
According to Gareth Halfacree, the WiFi performance was increased even if the same WiFi chip is used in the new Raspberry. The new CPU and memory seem to help a lot for the 5Ghz bands:
- Wifi throughput at 2.4Ghz: +5%
- Wifi throughput at 5Ghz: +200%
Ethernet speeds seem to be more or less the same.

Raspberry PI 5 power consumption
When running an identical workload, the Raspberry Pi 5 uses significantly less energy and runs noticeably cooler than the Raspberry Pi 4. However, due to the significantly higher performance ceiling, peak power consumption rises to about 12W for the most demanding workloads, as opposed to 6.4W for the Raspberry Pi 4. Idle power consumption is not yet confirmed.
- CPU Idle: ?? watts (vs 2.7 watts on the PI 4B+)
- CPU Loaded: 12 watts (vs 6.4 watts)
So yes, the new PI5 performance/price ratio is on top, outperforming the PI4 and many other clones, even the latest Orange PIs.
