The FCC photos show a design that appears to be almost identical to the quad-core, Cortex-A7 Raspberry Pi 2 Model B, which shipped a year ago. The system-on-chip continues to be a Broadcom model, but it's impossible to say whether it's an all 64-bit, ARMv8 SoC, such as a quad-core Cortex-A53 design, or a dual-core design, or perhaps even a half Cortex-A53, half Cortex-A7 Big.Little combo. The RAM allotment cannot be confirmed, but appears likely to stay the same at 1GB.
