Phoronix Experts Analyze Performance of Raspberry Pi 5
Phoronix experts conducted analysis on the performance of the new microcomputer Raspberry Pi 5 and noted a significant improvement compared to the previous Raspberry Pi 4 model. One notable enhancement is the optimized input-output system.
Raspberry Pi 5 Specifications
| Processor | Broadcom BCM2712 chip with a quad-core ARM Cortex-A76 processor |
|---|---|
| Clock Frequency | 2.4 GHz |
| Cache | 512KB cache for each kernel and a common L3 cache size 2MB |
| Ports | Two USB 3.0 ports, two USB 2.0 ports, Gigabit Ethernet port, two 4-channel MIPI transceivers, PCIe 2.0 X1 interface through the M.2 HAT adapter, 5V USB-C power, a standard 40-pin connector GPIO, and two Micro HDMI outputs |
Raspberry Pi 5 incorporates a specialized South Bridge processor (SouthBridge) RP1 to enhance the input and output functions. This processor improves the speed of USB input-output, doubles the peak performance of the SD card, and enhances connection capabilities through the PCI Express 2.0 interface.
The microcomputer is available in configurations with 4GB and 8GB of RAM LPDDR4X-4267 SDRAM. Additionally, it offers Wi-Fi 802.11ac, Bluetooth 5.0/Ble, and Microsd memory card support. However, the version with 16GB of RAM has not yet been announced.
Due to the more powerful chip and increased frequency of Cortex-A76 cores, effective cooling is crucial. In tests conducted without a heat sink, the average chip temperature reached 81°C, with a maximum of 89°C. However,
