The Intel Core i9-11980HK is a flagship 8-core, 16-thread mobile processor for gaming and creator laptops, built on Intel’s 10 nm SuperFin Tiger Lake-H architecture with up to 5.0 GHz single-core turbo and configurable 45–65 W TDP.
Intel’s Core i9-11980HK was the flagship of the 11th Gen Tiger Lake‑H lineup, offering 8 cores and 16 threads with a 2.6 GHz base (45 W) and up to 3.3 GHz base at 65 W cTDP, plus 5.
0 GHz single‑core turbo. It brought 20 PCIe 4.0 CPU lanes, DDR4‑3200, and Intel UHD Graphics 32 EU to gaming and mobile workstations, and competed directly with AMD’s Ryzen 9 5900HX/5980HX.
While still fast in 2026, its 10 nm SuperFin process and 45–65 W envelope lag behind newer Alder Lake, Raptor Lake, and Zen 4 mobile parts in efficiency and multi‑threaded performance.
Specifications
Performance
Capable in multi-threaded creator workloads, but 8 cores without efficiency cores trail newer hybrid designs in heavily threaded tasks.
Adequate for light VM use and local dev containers, but limited memory channels and core count make it less ideal than modern HX or desktop-replacement CPUs for heavy virtualization.
Strong single-threaded performance and high turbo clocks keep the 11980HK competitive in CPU-bound games, but modern 12th/13th Gen Intel and Ryzen 7000 H/HX chips often match or beat it while using less power.
The 10 nm SuperFin process and 45–65 W envelope result in high power draw and heat under load compared to newer Intel 7 and TSMC N5/N4 mobile CPUs.
- •5.0 GHz single-core turbo gives strong FPS in CPU-heavy titles.
- •Most gaming laptops pair it with RTX 3070/3080-class GPUs, where the CPU is rarely the bottleneck at 1080p/1440p.
- •Newer Alder Lake/Raptor Lake H/HX CPUs often deliver slightly better 1% lows and efficiency.
- •Intel Deep Learning Boost (AVX-512 VNNI) accelerates INT8 inference workloads.
- •No dedicated NPU; AI acceleration is modest compared to later Core Ultra and Ryzen AI mobile chips.

Architecture Overview
Tiger Lake-H is Intel’s 10 nm SuperFin high-performance mobile architecture, combining Willow Cove CPU cores with a 32 EU Xe-LP integrated GPU and 20 PCIe 4.0 lanes from the CPU.
CPU Design
Eight Willow Cove cores with Hyper-Threading provide 16 threads. Willow Cove improves on Sunny Cove with reworked caching and higher frequency potential on 10 nm SuperFin, enabling up to 5.0 GHz in the 11980HK.
Memory Subsystem
Dual-channel DDR4-3200 memory controller with up to 128 GB support and 51.2 GB/s bandwidth, a step up from 10th-gen H-series in clock speed and capacity.
PCIe & I/O
20 PCIe 4.0 lanes directly from the CPU (first for Intel H-series mobile) plus Gen 3 lanes from the PCH, enabling faster GPUs and NVMe SSDs than Comet Lake-H.
Overclocking
Unlike most mobile CPUs, the 11980HK features an unlocked multiplier, allowing overclocking in laptops with suitable BIOS and cooling.
- Move from 14 nm to 10 nm SuperFin with higher clocks and IPC.
- 20 PCIe 4.0 CPU lanes vs PCIe 3.0 on 10th-gen.
- Larger 24 MB L3 cache and DDR4-3200 support.
- Unlocked multiplier on mobile flagship.
Key Highlights
- 8 cores and 16 threads with high 5.0 GHz turbo
- 20 PCIe 4.0 CPU lanes for fast GPUs and storage
- Unlocked multiplier for overclocking in supported laptops
- Strong single-threaded performance for gaming and light tasks

- No hybrid architecture; 8 big cores only, trailing newer HX chips in multi-thread
- Platform is EOL with no upgrade path beyond existing laptop designs
- Integrated UHD Graphics 32 EU is basic; a discrete GPU is required for serious gaming or compute
History
The Core i9-11980HK debuted in mid‑2021 as the flagship of Intel’s 11th Gen Tiger Lake‑H family, representing the first 10 nm SuperFin high‑performance mobile platform. It answered AMD’s Ryzen 5000 H‑series with 8 Willow Cove cores and 5.0 GHz turbo, bringing 20 PCIe 4.
0 CPU lanes to laptops for the first time and an unlocked multiplier for enthusiasts. While it didn’t dethrone Ryzen in multi‑thread efficiency, it closed the gap in single‑core performance and gaming, and cemented Intel’s push toward higher‑clocked, more feature‑rich mobile CPUs. The 11980HK’s tenure was brief; by early 2022 Alder Lake‑H and HX chips had arrived with hybrid architectures and better efficiency, pushing Tiger Lake‑H into the discontinued column.
Improvements over Previous Generation
- Move from 14 nm to 10 nm SuperFin with higher clocks and IPC.
- 20 PCIe 4.0 CPU lanes vs PCIe 3.0 on 10th-gen.
- Larger 24 MB L3 cache and DDR4-3200 support.
- Unlocked multiplier on mobile flagship.
