== BCM2836

The Broadcom chip used in the Raspberry Pi 2 Model B. The underlying architecture in BCM2836 is identical to BCM2835. The only significant difference is the removal of the ARM1176JZF-S processor and replacement with a quad-core Cortex-A7 cluster.

IMPORTANT: This SoC is discontinued. Later Raspberry Pi 2 Model B revisions use a different SoC. For more information, see https://pip.raspberrypi.com/documents/RP-004577-PC-1?disposition=inline[Raspberry Pi 2 Model B Product Change Note].

== BCM2837

This is the Broadcom chip used in the Raspberry Pi 3 Model B, later models of the Raspberry Pi 2 Model B, and the Raspberry Pi Compute Module 3. The underlying architecture of the BCM2837 is identical to the BCM2836. The only significant difference is the replacement of the Armv7 quad core cluster with a quad-core Arm Cortex A53 (Armv8) cluster.
This is the Broadcom chip used in some models of Raspberry Pi 3 Model B, some models of Raspberry Pi 2 Model B, and Raspberry Pi Compute Module 3. The underlying architecture of the BCM2837 is identical to the BCM2836. The only significant difference is the replacement of the Armv7 quad core cluster with a quad-core Arm Cortex A53 (Armv8) cluster.

The Arm cores run at 1.2GHz, making the device about 50% faster than the Raspberry Pi 2. The VideoCore IV runs at 400MHz.

Please refer to the following BCM2836 document for details on the Arm peripherals specification, which also applies to the BCM2837.

* https://developer.arm.com/documentation/ddi0500/latest/[Cortex-A53 MPCore Processor Technical Reference Manual]

IMPORTANT: This SoC is discontinued. Raspberry Pi devices that include this chip reached End-of-Life on 16 October 2025. For more information, see https://pip.raspberrypi.com/documents/RP-009284-PC-2?disposition=inline[Raspberry Pi 2 Model B revisions 1.1 and 1.2 Obsolescence Notice 1] and https://pip.raspberrypi.com/documents/RP-009286-PC?disposition=inline[Raspberry Pi Compute Module 3 and Compute Module 3 Lite Obsolescence Notice 2].

If we're being totally complete, it's probably also worth linking to https://pip.raspberrypi.com/documents/RP-001029-PC-1 ?

And should probably mention BCM2837B0 in the "Raspberry Pi 3 Model B" section in documentation/asciidoc/computers/raspberry-pi/introduction.adoc too? (sorry!)

== BCM2837B0

This is the Broadcom chip used in the Raspberry Pi 3 Models A+, B+, and the Raspberry Pi Compute Module 3+. The underlying architecture of the BCM2837B0 is identical to the BCM2837 chip used in other versions of the Raspberry Pi. The Arm core hardware is the same, only the frequency is rated higher.

The underlying architecture of the BCM2837B0 is identical to the BCM2837 chip used in other versions of the Raspberry Pi. The Arm core hardware is the same; only the frequency is rated higher.

The Arm cores are capable of running at up to 1.4GHz, making the 3B+/3A+ about 17% faster than the original Raspberry Pi 3. The VideoCore IV runs at 400MHz. The Arm core is 64-bit, while the VideoCore IV is 32-bit.

Probably not worth mentioning that Raspberry Pi Compute Module 3+ and Raspberry Pi 2 Model B rev 1.3 only run the Arm cores at up to 1.2 GHz?

IMPORTANT: Raspberry Pi 2 Model B revisions 1.1 and 1.2 have reached End-of-Life (EoL) due to the discontinuation of the core SoC used in these products. The official EoL date was 16 October 2025. Raspberry Pi 2 Model B revision 1.3 offers the same mechanical footprint and a BCM2837B0 processor, and so is recommended for existing designs. For more information, see the official https://pip.raspberrypi.com/documents/RP-009284-PC-2?disposition=inline[Obsolescence Notice].

I think that @mudge told me that you can leave off the ?disposition=inline as long as the URL starts with /documents/... ?
