Number of ALUs don't define a core. But the fact that it has 4 FP units(2 threads each) has a lot to do with it performing like i7(QC with SMT). If it had beefier FP unit it would have performed much better in many workloads(not that i7 level of performance is bad though). The problem is that even with 4 of these FP "cores" and 8 integer cores(yes they are "true" cores) AMD is hitting the TDP ceiling on 32nm node. Proves that GloFo's process is a complete turd.
