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.

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.

Performance

The average 11800H in our database is a powerhouse, as of mid 2022. Its multi-thread performance is most comparable to that of the octa-core AMD Ryzen 7 5800H.

Thanks to its decent cooling solution and a long-term CPU power limit of 165 W, the Alienware x17 R1 is among the fastest laptops powered by the 11800H that we know of. It can be almost 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 series chip has a default TDP, also known as the long-term power limit, of 45 W that laptop makers are allowed to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so will result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The Core i7-11800H is built with Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.
