Intel Core i9-10880H Geekbench scores show a 7.5 to 13% improvement over the Core i9-9880H, within striking distance of the AMD Ryzen 7 3800X

Intel is likely to hasten the launch of Comet Lake-H and Comet Lake-S parts given the impending competition from AMD Ryzen 4000 Renoir APUs. Performance leaks about Comet Lake-H processors are steadily coming in and the latest is a couple of Geekbench scores for the Core i9-10880H.

Known leakster TUM_APISAK has managed to unearth two Geekbench 4.3.4 listings for the Core i9-10880H. Both the listings seem to indicate identical hardware. In the first of them, the Core i9-10880H with a base clock of 2.30 GHz and a boost clock of 4.88 GHz scored 5,847 points in single-core and 31,916 points in multi-core. In the other entry, the Core i9-10880H with a boost of 4.94 GHz scored 5,865 and 31,093 in single and multi-core tests, respectively. 

Now, we are not exactly sure of this additional 60 MHz boost frequency reported in the second Geekbench run. While there is a slight probability of Thermal Velocity Boost happening, it is more likely to be an error in Geekbench's reporting as the actual .gb4 page still shows the maximum frequency as "4880". 

The Core i9-10880H is a direct successor to the Core i9-9880H with the only perceivable difference in specs being the slightly increased boost clocks. However, going by the above numbers, we find do a ~5% increase in single-core and about 7.5% improvement in multi-core compared to the 9880H. The difference may go up to 13% depending on the laptop's cooling. The single-core scores are above what an AMD Ryzen 7 3800X posts and are well within reach of the Core i7-9700K. However, the Core i9-10880H looks to have an advantage in multi-core due to hyperthreading, which the 9700K lacks.

While we are aware of the Comet Lake-S lineup for desktops, there appears to be some confusion regarding the actual Comet Lake-H lineup. Although too early to infer, it appears that upgrading to Comet Lake-H many not yield tangible benefits if you already rock a notebook powered by Coffee Lake-H Refresh.
