Intel Core i9-11980HK

The Intel Core i9-11980HK is an 8-core, 16-thread mobile processor from Intel's Tiger Lake-H generation, built on the 10 nm process. It sits in the 87th percentile of all CPUs in the database, with an average benchmark score of 30469, placing it in a dead heat with several modern mid-range and upper-mid-range rivals. This is a high-end mobile part from 2021, now end-of-life, but its performance profile remains relevant for specific workloads.

Who Should Consider It

The benchmark results indicate this processor is a strong fit for users whose primary workload is multi-threaded content creation. The Cinebench R23 multi-core score of 19076 is substantial, and the PassMark multithread score of 22436 confirms that heavily threaded tasks like video encoding, 3D rendering, and software compilation will be handled with ease. For a mobile chip, this level of throughput puts it in contention with desktop parts from its era, making it suitable for a professional on the go who needs a portable workstation.

Gamers will find the i9-11980HK highly capable, though not because of its raw core count. The single-core performance is exceptional, evidenced by a Cinebench R23 single-core score of 2693 and a PassMark single-thread score of 3261. Many game engines rely heavily on single-thread speed, and these numbers indicate the chip can push high frame rates without bottlenecking a discrete GPU. The presence of an unlocked multiplier means users who have the ability to tune the processor can extract additional performance, though this is more relevant for enthusiasts in larger chassis with robust cooling.

For office and general productivity workloads, this processor is overkill but still effective. The PassMark integer math score of 78682 and data compression score of 266571 show that tasks like spreadsheet manipulation, database work, and file archiving are completed near-instantly. However, users who only perform these light tasks would be better served by a lower-tier chip, as the i9-11980HK's performance is wasted on basic word processing and web browsing. It is a specialist tool for those who need maximum compute power in a laptop form factor.

Power and Thermals

The Core i9-11980HK carries a 45 W TDP, which is the standard class for high-performance mobile processors in this segment. This TDP figure is the base power draw, and it implies that a laptop must have a capable thermal solution to sustain boost clocks. The 5.00 GHz boost clock is a demanding target, and a thin-and-light chassis will likely struggle to maintain it under full multi-core load, leading to reduced clocks over time.

Benchmark results suggest the chip can deliver its performance only when given adequate cooling headroom. The Cinebench R20 multi-core score of 8011 and R15 multi-core score of 1922 indicate sustained loads are possible, but these scores were likely achieved in a system with a robust cooling design. Users should expect that any laptop housing this processor will be thicker and heavier than standard ultrabooks, with larger fans and heat pipes to dissipate the thermal load. An unlocked multiplier also invites overclocking, which will push power consumption and heat output well beyond the 45 W baseline, requiring even more aggressive cooling solutions.

Benchmark Performance

The average benchmark score of 30469 places the i9-11980HK in a tight cluster with its nearest rivals, showing that its performance is still competitive against newer processors. It sits 0.1% ahead of the Intel Core Ultra 5 225T, which scores 30425, and 0.6% ahead of both the AMD Ryzen 7 PRO 6850H and the AMD Ryzen 5 8645HS, which score 30286 and 30273, respectively. The only rival that edges it out is the AMD Ryzen 9 PRO 6950H, which is 0.5% ahead with a score of 30629. These deltas are negligible in real-world use, indicating that the 11980HK is still a relevant performer against these modern parts.

In multi-threaded workloads, the chip’s 8 cores and 16 threads produce strong results. The Cinebench R23 multi-core score of 19076 is particularly notable, as it shows the chip can handle rendering and encoding tasks that would stall lower-core-count processors. The Cinebench R20 multi-core score of 8011 further validates this, and the PassMark multithread score of 22436 suggests consistent performance across a variety of threaded applications. The data indicates that the 11980HK is not a slouch in heavy compute tasks, even by modern standards.

Single-thread performance is where this chip shines most. The Cinebench R23 single-core score of 2693 and the Cinebench R20 single-core score of 1131 are high figures that rival or exceed many newer desktop processors. The PassMark single-thread score of 3261 is equally impressive, and the PassMark physics score of 1112 relies heavily on single-threaded efficiency. For users who run applications that are not perfectly multi-threaded, such as legacy software or certain simulation tools, this processor will deliver snappy responsiveness and quick calculation times.

Specialized workloads also show strength. The PassMark floating-point math score of 46262 and the extended instructions score of 17654 indicate that scientific computing and heavily vectorized code will run efficiently. The data encryption score of 13813 and random string sorting score of 31709 show that the chip handles cryptography and data manipulation tasks competently. The find prime numbers score of 100 is a baseline figure, but it does not detract from the overall performance picture.

Platform and Compatibility

The i9-11980HK uses the Intel BGA 1787 socket, which means it is soldered to the motherboard and is not upgradeable. This is a critical consideration for buyers, as the processor and board must be selected together as a complete package. The architecture is Tiger Lake-H, part of Intel's 11th Gen Core series, and it is built on the 10 nm process with a die size of 190 mm². The production status is end-of-life, so this chip is only available in existing laptops or on the used market.

Memory support is limited to DDR4, operating on a dual-channel bus with a bandwidth of 51.2 GB/s. This is an older memory standard, and it may limit performance in memory-sensitive applications compared to newer platforms that support DDR5. ECC memory is not supported, so this is not suitable for error-correcting workloads in servers or scientific workstations. The chip includes integrated graphics in the form of UHD Graphics 750, which provides a fallback display output, but it is not intended for gaming or GPU-accelerated compute.

For expansion, the CPU provides PCIe Gen 4 with 20 lanes. This grants fast connectivity for a discrete GPU and one or two NVMe SSDs. The upgrade path is non-existent due to the BGA socket, but the PCIe Gen 4 support ensures that storage and graphics devices will operate at their full potential. The chip was released on 2021-05-10, and its part number is SRKSZ. The launch MSRP is $583, though this is only a reference figure for the processor's initial cost.
