Intel Core i7-11800H
The Intel Core i7-11800H is a high-end octa-core SoC for gaming laptops and mobile workstations. It is belongs to the Tiger Lake H45 family and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to Hyper-Threading). The base clock speed depends on the TDP setting and is 2.3 GHz at 45 W. The single core Boost can be as high as 4.6 GHz while all cores can run at up to 4.2 GHz. The CPU offers 24 MB of Level 3 cache and supports DDR4-3200 memory.
Thanks to the new Tiger Lake architecture, the i7-11800H should be similar or faster than the old Intel Core i9-10875H (Comet Lake-H, 2.3 - 5.1 GHz, 16 MB L3) in single and multi threaded performance and similar to the Ryzen 7 5800H (Zen 3, 3.2 - 4.4 GHz, 16 MB L3). Therefore, the i7 is well suited for even very demanding tasks.
The SoC also has the improved UHD Graphics iGPU with 32 EUs which is similar to the Iris Xe iGPUs.
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 second-gen 10 nm Intel SuperFin process that should be comparable to the 7 nm TSMC (e.g. Ryzen 4000 series). The default TDP is 45 W at 2.3 GHz base speed, at 35 Watt the base clock speed decreases to 1.9 GHz (cTDP down).
