Raspberry Pi 5 在性能上实现了重大飞跃,得益于其 2.4GHz 四核 Arm Cortex-A76 处理器,CPU 速度较前代产品提升了 2 至 3 倍。这款最新型号配备了升级后的 800MHz VideoCore VII GPU、双 4Kp60 HDMI 输出,并首次采用了自研的“RP1”芯片。 主要技术改进包括: * **增强的 I/O:** RP1 南桥芯片使总 USB 带宽翻倍,并显著提升了 SD 卡性能。 * **连接性:** 具备更快的千兆以太网(支持可选的 PoE HAT)、双频 Wi-Fi,以及用于高带宽外设的全新 PCI Express 2.0 接口。 * **摄像头/显示:** 升级后的 MIPI 收发器支持最多两台摄像头或显示器,总带宽提升至原来的三倍。 Raspberry Pi 5 提供多种内存配置,包括 16GB 版本。用户需注意,由于硬件进行了全面重新设计,Pi 5 与 Raspberry Pi 4 的外壳不兼容。

16GB版本树莓派 5 以 350 美元的价格发布,在 Hacker News 上引发了激烈讨论,焦点在于该平台是否背离了其作为学生和爱好者平价电脑的初衷。 批评者认为这一价格高得离谱,并指出同样的预算可以买到性能更强的二手办公迷你主机(例如搭载 Intel N100 芯片的设备),甚至是二手的 Mac Mini。许多评论者认为树莓派已经“江郎才尽”,不再是通用计算领域具有成本效益的替代方案。 支持者则辩称,高昂的售价主要是因为树莓派所用内存的价格上涨了 700%。他们认为,350 美元的版本是专门为那些需要树莓派独特的 GPIO(通用输入/输出)引脚和成熟生态系统的用户提供的特殊产品。支持者强调,针对预算有限的用户,低内存版本的树莓派依然在售,即便在当前硬件行业内存价格普遍上涨的环境下,该平台在其特定定位上仍具价值。

The Raspberry Pi 5 is the newest Raspberry Pi computer, and the Pi Foundation knows you can always make a good thing better! And what could make the Pi 5 better than the 4? How about a faster processor, USB 3.0 ports, and an updated Gigabit Ethernet chip with PoE capability? Good guess - that's exactly what they did!

The Raspberry Pi 5 is the latest product in the Raspberry Pi range, boasting 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz with built-in metal heatsink, USB 3 ports, dual-band 2.4GHz and 5GHz wireless LANfaster Gigabit Ethernet, and PoE capability via a separate PoE HAT.

This version comes with 16GB of RAM, but we also carry the 2GB, 4GB, and 8GB, if you like.

Featuring a 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz, Raspberry Pi 5 delivers a 2–3× increase in CPU performance relative to Raspberry Pi 4. Alongside a substantial uplift in graphics performance from an 800MHz VideoCore VII GPU; dual 4Kp60 display output over HDMI; and state-of-the-art camera support from a rearchitected Raspberry Pi Image Signal Processor, it provides a smooth desktop experience for consumers, and opens the door to new applications for industrial customers.

For the first time, this is a full-size Raspberry Pi computer using silicon built in-house at Raspberry Pi. The RP1 “southbridge” provides the bulk of the I/O capabilities for Raspberry Pi 5 and delivers a step change in peripheral performance and functionality. Aggregate USB bandwidth is more than doubled, yielding faster transfer speeds to external UAS drives and other high-speed peripherals; the dedicated two-lane 1Gbps MIPI camera and display interfaces present on earlier models have been replaced by a pair of four-lane 1.5Gbps MIPI transceivers, tripling total bandwidth, and supporting any combination of up to two cameras or displays; peak SD card performance is doubled, through support for the SDR104 high-speed mode; and for the first time. the platform exposes a single-lane PCI Express 2.0 interface, providing support for high-bandwidth peripherals.

Please note the Pi 5 is a significant redesign, and Raspberry Pi 4 cases will not fit.
