The Sentosa uses a dual-core Broadcom 1250 processor
with an SB1 version 0.2 core. The board is BCM91250E
Revision 1.

The Swarm also uses a Broadcom 1250 with an SB1
version 0.2 core, but the board is a BCM91250A.

Most of the difference seems to be in the motherboard,
rather than the CPU, but I couldn't tell you what the
difference is between an E and an A, and why the A
seems better-behaved.
