Well, if you have a part number... :->

With QFP and similar devices, they come in standard pin arrays, so there
could be a lot of power pins (ISTR something about quad cache having a
particular problem with routing power around the silicon..?)

But if they are cache controllers, then then have to access 64-bit data
and 20-bit cache address (say), plus chip selects, interfaces with main
memory (could be on a different bus and multiplexed by the cache
controller, so call it another 64-bit data and 32-bit DRAM address).
All adds up...

If I could find the manual for my motherboard (never trust a woman to
tidy up - you'll never find anything ever again...), I could find out a
bit more about the Triton chipset.  Maybe it's on the Intel CDs at
work..?
