-ARM1176JZF chip with TrustZone (enables trusted computing environment for media, apps, network, OS, etc. -- very bad for hackers)
-Can vary in clock speed up to 700MHz or more, depending on implementation (thanks, Nigma)
-ARM Intelligent Energy Manager (claimed to reduce power consumption 25-50% in portables)
-16K / 16K cache
-Features vector floating point coprocessor ("for embedded 3D-graphics")
-ARM Jazelle enabled for embedded Java execution (hmm...)
-SIMD, high perf integer CPU (8-stage pipeline, 675 Dhrystone, 2.1 MIPS)
-0.45 mW/MHz power draw (with cache)
