Specifically:

http://www.xbitlabs.com/articles/graphics/display/zotac-geforce-gtx-titan-amp-edition-6gb-sli.html#sect0

Stock clocks:
837 MHz base, 876 MHz boost, 6008 MHz memory
Vendor o/c:
902 MHz base, 954 MHz boost, 6608 MHz memory

For comparison, GTX 780 stock clocks:
863 MHz base, 900 MHz boost, 6008 MHz memory

So stock Titan has lower clocks than stock GTX 780, but vendor o/c Titan
has higher clocks than stock GTX 780.
