    The SuperWorkstation SYS-551A-T supports one Intel Xeon W-series 4th Generation (LGA4677) processor.

    Hyper-Threading support allows two threads to run simultaneously on each core - recognizing up to 112 total cores, 56 real and 56 virtual. Turbo Boost support automatically boosts the processor speed based on workload - so if an application is only using one of the cores it will automatically increase the speed of the core in use and turn off the unused cores.
