The additional memory is intended to provide better performance when executing data-intensive applications, making it an attractive option for general desktop computer users.

The new computer has been developed to offer a balance of processing, storage and cost and 8 GByte memory is ideal for applications that feature the real-time processing of large amounts of data with minimum of latency. These applications can include edge gateways, machine vision and facial recognition. The new board’s functionality can be further enhanced for vision applications by using the recently released Raspberry Pi 12MP High-Quality Camera with interchangeable lenses.

The larger memory capacity of the 8 GB board will also be a boon to desktop user to support web browsing, ultra-high-definition video streaming, cloud gaming, and image processing without time delay or latency.

The 8 GByte Raspberry Pi 4 Model B computer offers

  • 28 nm BCM2711 SoC delivers a significant increase in energy efficiency over previous models.
  • Quad-core ARM Cortex-A72 64-bit processor clocked at 1.5 GHz enable the Raspberry Pi 4 Model B computer to run up to three times faster than its predecessor.
  • Two micro HDMI ports support dual-display output at resolutions up to 4K.
  • Two SuperSpeed USB 3.0 ports, enabling faster transfer rates to mass-storage devices (up to 5 Gbps).
  • True Gigabit Ethernet connectivity delivering network data rates of up to 1 Gbps.
  • Dual-band wireless networking at 2.4 GHz and 5 GHz, delivering real-world data rates in excess of 100 Mbps. Modular compliance certification allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.

Other key features include

  • Multimedia:
    • H.265 decode (4kp60),
    • H.264 decode (1080p60);
    • H.264 encode (1080p30);
    • OpenGL ES 3.0 graphics;
    • hardware image sensor pipeline.
  • GPIO:
    User definable GPIO on standard 40-pin header with full backward compatibility and additional multiplexed UART, I2C and SPI peripherals.
  • SD card support:
    Micro SD card slot for loading operating system and data storage.
  • Power over Ethernet:
    PoE support using separate HAT accessory.

Eben Upton, Raspberry Pi Trading Chief Executive, said: "This is a product that we've been looking forward to releasing since the launch of Raspberry Pi 4 in June 2019, and now, enabled by our close relationship with our memory partners at Micron, it has finally become a reality. This product, and our forthcoming 64-bit Debian-based operating system will open up a wide range of new high-end applications for the Raspberry Pi platform."
