This $12,000 computer, dubbed Project Erebus v2.5 by creator d3ad0ne, contains eight AMD Radeon HD7970 GPU cards. Running version 0.10 of oclHashcat-lite, it requires just 12 hours to brute force the entire keyspace for any eight-character password containing upper- or lower-case letters, digits or symbols. It aided Team Hashcat in winning this year's Crack Me If You Can contest.

Assuming that's using the same keyspace, that's only 96^8 combinations, which is a difference of:

296950881580502692976440171464717149487929275664112415506432


EDIT: I messed up initial calculation, the loop didnt get to 96^30, there is actually 296950881580502692976440171464717149487929282878008205344768
possible combinations.
