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 for gaming as well as any other task imaginable in 2021 or 2022. Multi-thread performance is most comparable to the octa-core AMD Ryzen 7 5800H; as is usually the case with higher-end laptop-grade processors, a competent cooling solution together with appropriately high Power Limits are a must for getting every bit of performance possible out of the CPU.

Power consumption

This Core i7 has a default TDP (also known as the long-term power limit) of 35 W to 45 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. Either way, a high-performance cooling solution is a necessity.

Core i7-11800H is built with Intel's second-gen 10 nm process marketed as SuperFin for decent, as of late 2022, energy efficiency.
