Benchmarks explore how the Intel Xeon 678X 'Granite Rapids WS' workstation processor scales in performance, power draw, frequency, and thermal behavior when limited to 6, 12, 24, and 48 cores, plus the default 48-core with Hyper-Threading configuration. Tests ran on an HP Z4 G6i workstation with 128GB DDR5-6400 memory and a 2TB NVMe SSD under Fedora 44 with the Linux 7.1 kernel and GCC 16.1 compiler, tracking peak frequency, RAPL-measured power, core temperature, and performance-per-watt across the core counts.
