Intel Core i9-11900KB vs AMD Ryzen 5 2400G vs Intel Core i7-11800H

Intel Core i9-11900KB

► remove from comparison Intel i9-11900KB

The Intel Core i9-11900KB is an Octa-Core-CPU that was used in the Intel Beast Canyon NUC. It is based on the Tiger-Lake-H45 series and was announced in the second quarter of 2021. The processor cores can clock from 3.3 to 5.3 GHz, all cores at once can reach up to 4.9 GHz. The CPU features 24 MB level 3 cache and DDR4-3200 memory. The integrated UHD graphics card is based on the Xe-architecture with 32 cores and clocks up to 1.45 GHz.

As with the slower Tiger Lake-H CPUs, the 11900KB has a partly integrated WiFi 6E and Thunderbolt 4 in the chip. Furthermore, the 11900KB supports 20 PCIe 4.0 lanes.

The TDP is rated at 65 Watt with 3.3. GHz base clock and can be configured to 55 Watt (cTDP-down).

AMD Ryzen 5 2400G

► remove from comparison AMD R5 2400G

The AMD Ryzen 5 2400G is a desktop APU that was announced in early 2018. It is the fastest Raven Ridge APU at that time and features all four Zen cores (8 threads due to SMT support) clocked at 3.6 - 3.9 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (all of the 704 Shaders on the chip) clocked at up to 1250 MHz. The integrated dual-channel memory controller supports up to DDR-2933. The TDP is specified at 65 Watt and the CPU, GPU and memory are unlocked for overclocking. More information on Raven Ridge can be found in our launch article.

Intel Core i7-11800H

► remove from comparison Intel i7-11800H

The Intel Core i7-11800H is a high-end octa-core SoC for gaming laptops and mobile workstations. It is belongs to the Tiger Lake H45 family and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to Hyper-Threading). The base clock speed depends on the TDP setting and is 2.3 GHz at 45 W. The single core Boost can be as high as 4.6 GHz while all cores can run at up to 4.2 GHz. The CPU offers 24 MB of Level 3 cache and supports DDR4-3200 memory.

The SoC also has the improved UHD Graphics iGPU with 32 EUs which is similar to the Iris Xe iGPUs.

Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.

Performance

The average 11800H in our database is a powerhouse, as of mid 2022. Its multi-thread performance is most comparable to that of the octa-core AMD Ryzen 7 5800H.

Thanks to its decent cooling solution and a long-term CPU power limit of 165 W, the Alienware x17 R1 is among the fastest laptops powered by the 11800H that we know of. It can be almost 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 series chip has a default TDP, also known as the long-term power limit, of 45 W that laptop makers are allowed to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so will result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The Core i7-11800H is built with Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.
