You have not been completely misinformed. It depends on how you look at it. Hyperthreading does increase CPU utilization but not overall throughput. If CPUs are 100% busy, hyperthreading will not do any good. Advertising one CPU as two is misleading unless the key words "physical" and "logical" are mentioned.
