Okay. That makes perfect sense, but I will still argue that if that 
correct, using that terminology in the Top500 list doesn't make sense. 
An SoC is equivalent to a motherboard, but for regular Intel/AMD 
systems, they list the processor model, not the motherboard, so to list 
BQC instead of POWER A2 for the BG systems is inconsistent. As an 
example, compare the Sequoia description from the Top500 list to 
Stampede, which is just a regular x86 system:

*Sequoia*: BlueGene/Q, Power BQC 16C 1.60 GHz, Custom, 
<http://top500.org/system/177556>
IBM

*Stampede*: PowerEdge C8220, Xeon E5-2680 8C 2.700GHz, Infiniband FDR, 
Intel Xeon Phi SE10P, <http://top500.org/system/177931>
Dell
