Very strange cache as noted, maybe the core count is more of a headliner/sales tactic? Seems like most applications that would make use of more cores would also do well with the additional (or even higher than previous) cache.
While 6-core mobile parts are inevitable, I feel like the issues with cache layout and the name(Why would a 6 core part have the classification HQ, the Q specifically designated it as a quad core?) are more likely oversites by someone fabricating the leak.
