The Raspberry Pi is a fun development kit designed to encourage kids to join the programming career in an ultra-benefit way. However, this motherboard has only a credit card-sized device, and has already produced a large number of fans outside the education system, and sold millions of units in the first year. Today, the Raspberry Pi announced on the official website that the Raspberry Pi 4 is officially on sale. It has three times the processing power of the previous generation Raspberry Pi 3+ and four times the multimedia performance.
The Raspberry Pi 4 introduces new selling points, such as 64-bit processors, 802.11ac dual-band Wi-Fi, and Power over Ethernet (PoE) via HAT. The Raspberry Pi 4 released today not only improves computing and multimedia performance, but also features a quad-core ARM Cortex-A72 processor running at 1.5GHz, Gigabit Ethernet, Bluetooth 5.0, and USB 3.0 connectivity.
The increased performance means that the Raspberry Pi 4 can support high dynamic range (HDR) 4K p60 HEVC video decoding and simultaneously drive two 4K displays. At the same time, this is the first time consumers can choose 1GB / 2GB / 4GB RAM, and the starting price is maintained at 35 US dollars.
Technical specs for the Raspberry Pi 4 are:
- A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
- 1GB, 2GB, or 4GB of LPDDR4 SDRAM
- Full-throughput Gigabit Ethernet
- Dual-band 802.11ac wireless networking
- Bluetooth 5.0
- Two USB 3.0 and two USB 2.0 ports
- Dual monitor support, at resolutions up to 4K
- VideoCore VI graphics, supporting OpenGL ES 3.x
- 4Kp60 hardware decode of HEVC video
- Complete compatibility with earlier Raspberry Pi products
