Hello everyone!
I am Raspberry Pi 4, your tiny,dual-display,desktop computer robot brains,smart home hub,
media centre,networked AI core,factory controller,and much more! My speed and performance
is a step up from earlier Raspberry Pi models.
1. Completely upgraded, re-engineered ,faster, more powerful.
Kept all software backwards-compatible, so what you create on a Raspberry Pi 4 will work on
any older models you own too.
2.Dual displays 4K output
You can run two monitors at once — and in 4K
3. More RAM memory.
1GB, 2GB or 4GB for your choice (please confirm which one you need when order)
4. Two USB 3 ports
Can transfer data up to ten times faster.
Main Differences Between Raspberry 4 Model B & Raspberry Pi 3 B+
Spec | Raspberry Pi 4 B | Raspberry Pi 3 B+ |
CPU | 1.5-GHz, Quad-Core Broadcom BCM2711B0 (Cortex A-72) | 1.4-GHz, Quad Core Broadcom BCM2837B0 (Cortex A-53) |
RAM | 1 - 4GB DDR4 | 1GB DDR2 |
GPU | 400 MHz VideoCore IV | 500 MHz VideoCore VI |
Video Out | dual micro HDMI ports | single HDMI port |
Max resolution | 4K 60 Hz + 1080p or 2x 4K 30 Hz | 2560 x 1600 |
USB Ports | 2x USB 3.0 / 2x USB 2.0 | 4x USB 2.0 |
Wired Networking | Gigabit Ethernet | 330 Mbps Ethernet |
Wireless | 802.11ac (2.4 / 5 GHz), Bluetooth 5.0 | 802.11ac (2.4 / 5 GHz), Bluetooth 4.1 |
Charging Port | USB Type-C | micro USB |
Power Requirement | 3A, 5V | 2.5A, 5V |
Size | 3.5 x 2.3 x 0.76 inches (88 x 58 x 19.5mm) | 3.2 x 2.2 x 0.76 inches (82 x 56 x 19.5mm) |
Weight | 0.1 pounds (46 grams) | 0.11 pounds (50 grams) |
On the Sysbench CPU test, the Pi 4 B was capable of performing 394 events per second as compared to 263 for the Pi 3 B+. That's a difference of 50 percent.
The RAM is also quite a bit quicker, going from 1GB of DDR2 RAM operating on the Pi 3B+ to up to 4GB of DDR4 RAM. In addition to the increased bandwidth, having more memory is a huge deal, particularly for web surfing.
