The Raspberry Pi 4 is the latest product in the Raspberry Pi range, boasting an updated 64-bit quad core processor running at 1.4GHz with built-in metal heatsink, USB 3 ports, dual-band 2.4GHz and 5GHz wireless LAN, faster (300 mbps) Ethernet, and PoE capability via a separate PoE HAT.
The speed and performance of the new Raspberry Pi 4 is a step up from earlier models. For the first time, it comes with a complete desktop experience. Whether you're editing documents, browsing the web with a bunch of tabs open, juggling spreadsheets or drafting a presentation, you'll find the experience smooth and very recognizable — but on a smaller, more energy-efficient and much more cost-effective machine.
You can still utilize all your favorite Raspbian or PIXEL software with this update. You just need to upgrade your Raspbian operating system, Install the latest version so that the firmware can support all the latest chips! Previous SD cards from past releases will not work without an upgrade..
Desktop Level Experience: The faster 1.5GHz 64-bit quad-center CPU on the Raspberry Pi 4's Cortex A72 SoC, combined with the up to 4GB LPDDR4 RAM give execution practically identical to entry level x86 desktop PCs. You'll see altogether quicker boot speeds, and much better execution for CPU-heavy tasks like imitating and media focus use; a lot snappier all round!
Significantly Faster IO: The Raspberry Pi 4 has two USB 3.0 ports, for up to 10x faster transfer speeds than USB 2.0, perfect for connecting fast peripherals like SSDs and flash drives. There are also two USB 2.0 ports for connecting less speed-dependent peripherals like keyboards and mouse.
Dual Micro-HDMI, 4K Display Support: There are dual micro-HDMI ports that help up to 4Kp60, to use your Raspberry Pi 4 with a lot bigger presentations with fresh, sharp, high goals. Utilize the H.265 4Kp60 hardware decoding to watch 4K motion pictures in your preferred media device.
Power: Raspberry Pi 4 supports modern USB Type-C connector for power supply. This supports an extra 500mA of current, ensuring 1.2A for downstream USB devices, even under heavy CPU load.
Silent, energy-efficient: The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers.
Fast networking: Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth.
Your Choice of RAM: Different variants of the Raspberry Pi 4 is available, depending on how much RAM you need — 2GB, 4GB or 8GB.
- A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance).

Raspberry Pi 4 Model B
Your positive feedback brightened our day! We appreciate your kind words :)
Got my RPI4 8gb quite a while ago, now running mostly Ubuntu 22.04.2 from a USB 3.0 SSD enclosure with 256gb NVMe SSD, all sorts of things to learn more about, things like Wireshark, "GIMP" (GNU Image Manipulation Program), a Wordpress server (very helpful for testing things away from production servers), lots of built-in Ubuntu utilities (really, largely Debian things, where Ubuntu is based on), I could go on and on. If I want to boot up Debian instead, all I need to do is unplug the SSD (before booting!) and then power-up, because Debian is loaded on the MicroSD card and the firmware is setup to boot from the card if the USB is not present. Sweet!
I worked for a company in the late 1980s to late 1990s that had AT&T Unix Svr3 used as a file server in front of their proprietary product system, so I had some experience with that, then IBM's AIX (a Unix variation) but this little beast has so much to offer in terms of flexibility as part of a "home lab" and learning tool potential, not to mention the open source community's support of OSes and other software. No wonder they have been so tough to get hold of! It will be interesting to see where the RPIs go with the RISC-V spec devices that are beginning to pop up (including heavy support from China, I understand) , once they get more mature.
We're thrilled to hear you had a positive experience! Thanks for your support!
Managed to grab one (it's tough these days), works perfectly. Used the Raspberry PI imaging tool and then plug & play. Decided to use a Samsung Evo MicroSD Card (128gb)
