You forgot the "journalist touch". To spike interest:

"PadLock ACE encrypts at rates of up to 12.5 Gigabits per second (Gbps)
with a 1GHz VIA C3 processor, more than eight times faster than the best
software AES implementation from a power hungry 3GHz Intel® Pentium® 4
processor based system that encrypts at a rate of a mere 1.5 Gbps."

25 times faster, clock by clock :)
