Yes, some difficult to quantify amount of power, depending on what the CPU is doing.

Access to the North Bridge is probably the only thing that can throw the die dissipation measurement off significantly. An ideal load program would operate in the CPU's internal cache only.

Considering how little the die temperature fluctuates when running CPU Burn, and how clearly you can see the impact of cache size with Prime95, I think it's reasonable to believe that CPU Burn is not doing much North Bridge access. Maybe someone should contact the author(s) of CPU Burn and see what they say about this.
