Intel Core i9-11900H

The Intel Core i9-11900H 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 2.5 GHz. The single core boost speed can reach up to 4.9 GHz, 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 new Tiger Lake architecture, the i9-11900H should be similar or faster than the old Intel Core i9-10885H (Comet Lake-H, 2.4 - 5.3 GHz, 16 MB L3) in single and multi threaded performance and similar to the Ryzen 9 5800H (Zen 3, 3.2 - 4.4 GHz, 16 MB L3). Therefore, the i9 should be one of the fastest laptop CPUs in 2021 and well suited for even very demanding tasks.

The SoC also included the improved Xe graphics card called UHD graphics with all 32 EUs.

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.

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 is rated at 45 W at 2.5 GHz base speed, at 35 Watt the base clock speed decreases to 2.1 GHz (cTDP down).
