The new BCM2836 SoC is more or less the old BCM2835 with the ARMv6 core cut out and a v7 quad core dropped in it’s place. However there are some other minor changes can you talk about those?
There aren’t any changes to the USB subsystem, but the power system has received a tweak. 2835 has an on-board SMPS: this wasn’t large enough to supply the current needed by the quad Cortex complex, so it was removed, and Pi 2 uses an external SMPS chip. Also, as the Cortex complex has its own 512KB L2 cache, we no longer use the 128KB system L2 — ARM traffic goes directly to SDRAM instead.
