The Intel Core i9-11980HK is a high-end octa-core SoC for gaming laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.6 GHz. The single core boost speed can reach up to 5 GHz (ITBM 3.0, also two cores), all cores can reach up to 4.5 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. Thanks to the free multiplicator, the CPU can also be easily overclocked (but may not have much headroom).
The average 11980HK in our database matches AMD Ryzen 7 4800H in multi-thread performance, rendering the i9 a decent, if not slightly underwhelming CPU for gaming laptops and high-performance mini-PCs.
Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.
Professional management features like Intel vPro, SIPP or TXT are not supported by the 11980HK unlike the similar i9-11950H and Xeon W-11955M (with ECC support).
The chip is produced on the improved 10nm process (called 10nm SuperFin) at Intel, which should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series). The default TDP (PL1) is rated at 45 W, at 65 Watt the base clock speed increases to 3.3 GHz (cTDP up). The short burst PL2 is specified at 107 Watt for the base profile and 135 Watt for the performance profile.
