The Acorn site is up now. Here's the note:
Significant StrongARM features
* 202MHz core clock
* 5-stage pipeline (Fetch, Issue, Execute, Buffer, Write)
* Separate 16K write-back data cache and 16K instruction cache
* 8 entry write buffer, each entry holding 1-16 bytes
* Fast 32 and 64 bit result multiply instructions
* Averages fewer cycles per instruction than previous ARMs
So the key difference is that it's just a faster all-around chip.
