My reliable source appears to have been mistaken!  The
new Top500 press release says:

# Unlike the Chinese system it displaced from the No. 1
# slot and other recent very large system, the K Computer
# does not use graphics processors or other accelerators.

Chips are (according to @HPC_Guru):

# The K uses a SPARC6 VIIIfx CPU designed by #Fujitsu:
# 8 cores, 45nm, 128 Gflops, 2.2 Gflops/Watt

cheers,
Chris
