Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth (4GB)
Bottom line: The Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth ($121.96 on Amazon as of 2026-10-07): Quad-core Cortex-A72 at 1.5GHz handles 64-bit desktop Linux, not just headless scripts; main trade-off: needs a 5.1V/3A USB-C supply; most phone chargers will not hold the rail steady.

Pros & Cons
Pros
- ✓ Quad-core Cortex-A72 at 1.5GHz handles 64-bit desktop Linux, not just headless scripts
- ✓ 4GB LPDDR4-2400 leaves room for containers, browser tabs, or a Pi-hole plus Home Assistant
- ✓ True Gigabit Ethernet, no longer sharing bandwidth with the USB controller
- ✓ Two USB 3.0 ports make booting from an external SSD far faster than SD card storage
- ✓ Dual micro HDMI outputs drive two displays at up to 4Kp60
Cons
- ✗ Needs a 5.1V/3A USB-C supply; most phone chargers will not hold the rail steady
- ✗ Micro HDMI means new cables or adapters if you own standard HDMI leads
- ✗ No onboard storage at all, so a micro SD card is a mandatory extra purchase
- ✗ PoE requires a separate HAT that is not included in the box

SpecPicks Verdict
SpecPicks scored Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth using a rating × review-volume × price-fit model applied to published specs and reviews across the single board computers category. Raspberry Pi's single board computers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for single board computers of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
How much RAM does this Raspberry Pi 4 have, and is 4GB enough?
This is the 4GB LPDDR4-2400 variant. 4GB comfortably runs a 64-bit desktop, media center, Pi-hole, Home Assistant, or several Docker containers; heavy multi-container or in-memory database work is where you would want more.
What power supply does the Raspberry Pi 4 Model B require?
It requires 5.1V at 3A delivered over USB Type-C. You can alternatively power it over Ethernet via the GPIO PoE feature, but that needs a PoE HAT, which is not included.
Does it include a micro SD card or an operating system?
No. The board has a micro SD card slot for loading the operating system and storing data, but the card itself is a separate purchase. Check the product listing for what is included in your specific bundle.
Can it drive two monitors at once?
Yes. There are two micro HDMI ports supporting up to 4Kp60 video resolution. Note the connector is micro HDMI, so you will need micro-HDMI-to-HDMI cables or adapters.
How does the networking compare to the Raspberry Pi 3?
The Pi 4 adds 5.0GHz 802.11ac alongside 2.4GHz Wi-Fi, Bluetooth 5.0, and full-rate Gigabit Ethernet that is no longer throttled by the shared USB bus, plus two USB 3.0 ports for fast external storage.
