Yes, it is. But AMD market them as true quad-core as their scale. They should have point that. But they are not traditional quad core/hexa core/octo core.
New fx cpus are module(core) with two integer core/thread. The "module", described as two logical cores, can be contrasted with a single Intel core with HyperThreading. The only difference between the two approaches is that Bulldozer provides dedicated schedulers and integer units for each thread, whereas in Intel's core all threads must compete for available execution resources.
AMD misleading people by marketing them as multi-core processor. They should have stop doing this. Money dont fall from tree. People should have buy i3 cpu which is better than FX quad core(a true dual core).
