AFAIK Hardcopy is a structured ASIC so it should be approximately as expensive as an ASIC.
And you understanding of "Hyperthreading" (the Intel term - marketing garbage) A.K.A. SMT/Simultaneous Multi-Threading is wrong. If one run one thread on a core it will reach 100% of the performance, if one runs two threads one often get 85%+ per thread. SMT is a way to make use of stall cycles, not a way to execute two threads with barrel processing.
