Here's a smaller implementation:
"90nm implementation of AES-ECB with 256-bit key"
"13 000 gates", "2742 Mb/s"
That's 21 million AES blocks per second in 13k gates.
The clock rate is not mentioned, though. Perhaps it's already higher
than 250 MHz, maybe twice higher.
"The AES IP has a strong track record of silicon implementation with
volume production in 130nm and 65nm."
Hmm, volume production in 130nm and 65nm, but somehow the speed numbers
are given for 90nm - weird.
