Intel Core i9-9880H

The Intel Core i9-9880H is a high-end processor for laptops with eight cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.3 - 4.8 GHz (4.1 GHz with 8 cores) and can execute up to sixteen threads simultaneously thanks to Hyper-Threading. The 4.8 GHz can only be reached using the "Thermal Velocity Boost" which allows one core to boost to 4.8 GHz (+200 MHz) as long as the CPU temperature is below 50°C. Multiple cores can be boosted +100 MHz below 50°C (not verified). Compared to the predecessor, the Core i9-8950HK, the 9980H is based on the same architecture but offers 2 more cores.

According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i9-8950HK is the fastest model of the Coffee-Lake-H series at the time of announcement and offers an unlocked multiplier for overclocking of the CPU.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).


Due to the two additional cores, performance has increased by almost 33% compared to a similar clocked predecessor and even up to 100% compared to older Kaby-Lake quad-cores. Single thread performance however only improved slightly and the multi-core performance is heavily depending on the cooling.


The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i9 is only suited for big laptops with good cooling solutions.
