And, until Raspberry Pi 4, it was not an impressive option as a quick desktop replacement. + +So, yes, Raspberry Pi 4 changed the game with its new capabilities. But, how does it compare to Raspberry Pi 3? + +Is Raspberry Pi 3 still worth considering? Or, should you go for the latest and greatest Raspberry Pi 4? + +In this article, we try to get you some answers to that by highlighting some key differences between the two. + +First, let us look at the specifications both offer. + +### Raspberry Pi 3 specifications + +![][1] + +Raspberry Pi 3 checks all the boxes for a basic starter DIY project. If [Raspberry Pi Zero or Raspberry Pi Zero W][2] does not suit your requirements, Raspberry Pi 3 is a sweet spot without spending a lot. + + * Quad Core 1.2GHz Broadcom BCM2837 64bit CPU + * 1GB RAM + * Wireless LAN and Bluetooth Low Energy (BLE) + * Ethernet + * 40-pin extended GPIO + * 4 x USB 2 ports + * 4 Pole stereo output and composite video port + * Full size HDMI + * CSI camera port + * DSI display port + * Micro SD port for operating system and storing data + * Upgraded switched Micro USB power source up to 2.5A + + + +### Raspberry Pi 4 Specifications + +![][3] + + * Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz + * 2 GB, 4 GB or 8 GB LPDDR4-3200 + * 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE + * Gigabit Ethernet + * 2 x USB 3.0 ports + * 2 x USB 2.0 ports. + * 40 pin GPIO header (backwards compatible) + * 2 × micro-HDMI ports (up to 4kp60 supported) + * 2-lane MIPI DSI display port + * 2-lane MIPI CSI camera port + * 4-pole stereo audio and composite video port + * H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode) + * OpenGL ES 3.1, Vulkan 1.0 + * Micro-SD card slot for operating system and storing data + * 5V DC via USB-C connector + * 5V DC via GPIO header + * Power over Ethernet + + + +### Memory (RAM) options + +With Raspberry Pi models, usually, you get a single product lineup including 1 or 2 GB of RAM. + +And, that is the case with Raspberry Pi 3 B+. If you do not need more memory, Raspberry Pi 3 can prove to be a decent solution for all the usual DIY projects you used it with. + +However, with Raspberry Pi 4, you get the choices of a 2 GB, 4 GB, and 8 GB variant. So, if you want to get more things done, or achieve multiple tasks on your Raspberry Pi board, the Raspberry Pi 4 should be a great option. + +### Performance differences + +Even though both the boards feature chips from Broadcom, Raspberry Pi 4 offers significantly faster performance. + +If you want to use it as your mini-desktop replacement or want better computing power for your tasks, Raspberry Pi 4 will be the obvious pick. + +When it comes to Raspberry Pi 3, it packs in a Quad-Core 1.2GHz Broadcom BCM2837 64-bit CPU. It is a capable chip for a variety of tasks. + +#### Connectivity capabilities + +Both the Raspberry Pi boards provide a 40-pin extended GPIO header. + +However, when it comes to USB connectivity, Raspberry Pi 4 provides two USB 3.0 ports along with two more USB 2 ports. And, the Raspberry Pi 3 limits to two USB 2 ports. + +So, if you require faster data transfer speeds, USB 3.0 ports should be of help. For instance, if you are going to use any [media server software][4], this could come in handy. + +In addition to this, there’s also the presence of USB-C on Raspberry Pi 4 which can be used to power up (5V DC) the board if the USB accessories need it. + +#### Dual-Monitor & camera support + +While the Raspberry Pi 3 offers a full-size HDMI port, DSI port, and CSI port, it does not feature dual-monitor support. + +With Raspberry Pi 4, you get two micro-HDMI ports, a two-lane DSI port, and a two-lane CSI camera port. + +#### Awesome Raspberry Pi Projects to Check Out + +25 Raspberry Pi projects anyone can follow! + +[Raspberry Pi Projects][5] + +### Which one should you get? + +**Specifications** | **Raspberry Pi 3** | **Raspberry Pi 4** +---|---|--- +**Processor** | Quad-Core 1.2GHz Broadcom BCM2837 | Quad-Core 1.5 GHz Broadcom BCM2711 +**RAM** | 1 GB | Up to 8 GB +**Bluetooth** | BLE | Bluetooth 5.0 +**USB Ports** | 4 x USB 2.0 | 2 x USB 3.0 +2 x USB 2.0 +**Wireless Connectivity** | Yes | Yes, 2.4 GHz & 5 GHz band support +**Display Ports** | 1 x HDMI +1 x DSI | 2 x micro-HDMI +1 x DSI +**Power Supply** | microUSB & GPIO up to 2.5 A | 5V DC via USB-C and GPIO (3 A) +**MicroSD Slot** | Yes | Yes +**Price** | $35 | $35 (1 GB RAM), $45 (2 GB RAM), $55 (4 GB RAM), $75 (8 GB RAM) + +Raspberry Pi 4 is an excellent choice if you want faster data transfer, dual-monitor support, and better performance. + +Considering the price for a Raspberry Pi 4 base variant with 2 GB RAM costs about $35. It just does not make sense to opt for the 1 GB Raspberry Pi 3 model at nearly the same price. + +Of course, unless you get a cheaper deal and have a specific requirement. Raspberry Pi 4 is a clear choice overall. + +However, there are a few things like board heating and other potential issues that you may want to explore before deciding. Raspberry Pi 3 has proven to work with many projects and Raspberry Pi 4 is fairly new that may not have been tested with various projects. + +Once you’re sure about this, you can proceed to get any of them. + +What do you prefer to use?
