11th Gen Intel Core i9 11900H Review

Launched May 2021, the 11th Gen Intel Core i9 11900H is the flagship of Tiger Lake H, an 8-core, 16-thread processor running a 2.5 GHz base clock that boosts to 4.9 GHz within a 45 Watt TDP.

As the top Tiger Lake H chip, it carries the same Willow Cove architecture and large 24MB L3 cache as the i7 11800H below it, with a higher boost clock ceiling that made it Intel's premier gaming and creator laptop chip through 2021.

Intel UHD Graphics Xe G4 (48 EU)

A modest integrated GPU relative to the U-series Iris Xe configurations, reflecting this flagship H-series chip's design priority around pairing with a discrete GPU for actual gaming.

How Is the Core i9 11900H in Terms of Performance

As Tiger Lake H's flagship, this chip delivers genuinely top-tier mobile performance for 2021, with the 4.9 GHz boost clock and large cache giving it a real edge over the i7 11800H below it in both single and multi-threaded work.

Benchmarks

Cinebench R23 multi-core scores of 12,677 and single-core scores of 1,452 place this chip at the top of Intel's 2021 mobile lineup. Geekbench 5 multi-core scores of 9,099 confirm genuinely flagship-tier performance, ahead of the i7 11800H's 9,041 in this metric by a modest margin.
