The Intel Core i7-11800H is a mobile processor with 8 cores, launched in May 2021, at an MSRP of $395. It is part of the Core i7 lineup, using the Tiger Lake-H architecture with BGA 1787. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. Core i7-11800H has 24 MB of L3 cache and operates at 1900 MHz by default, but can boost up to 4.6 GHz, depending on the workload. Intel is making the Core i7-11800H on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Core i7-11800H, which limits its overclocking potential.
With a TDP of 35 W, the Core i7-11800H consumes only little energy. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 3200 MT/s. For communication with other components in the system, Core i7-11800H uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 750 integrated graphics solution.
Hardware virtualization is available on the Core i7-11800H, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
