The Raspberry Pi 4 Model B was launched in June 2019 with Broadcom BCM2711 Arm Cortex-A72 processor coupled with either 1, 2, or 4GB LPDDR4 RAM.

But there were expectations that a Raspberry Pi 4 with 8GB RAM or an 8GB eMMC flash may be eventually launched, as some of the user guides read “Product name: Raspberry Pi 4 Model B 1 GB, 2 GB, 4 GB + 8 GB variants”. We now know the answer as the Raspberry Pi Foundation has just introduced Raspberry Pi 4 with 8GB RAM.

Raspberry Pi 4 8GB specifications are the same except for the RAM capacity:

• • SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @  1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics
