Intel Core i9-11900KB vs Intel Core i5-11500B vs Intel Xeon W-11855M

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).

Intel Core i5-11500B

► remove from comparison Intel i5-11500B

The Intel Core i5-11500B is a hexa-core processor for desktops and mini PCs. It is based on the Tiger Lake architecture (H45) and was presented in Q2 2021. The chip offers a TDP of 65 watts (configurable). The six processor cores can clock from 3.3 to 4.6 GHz (single-core turbo). The processor offers 12 MB level 3 cache and supports DDR4 RAM with up to 3,200 MT/s. The integrated graphics are based on the Xe architecture and are named UHD Graphics (32 EUs). In the 11500B it clocks from 350 to 1,450 MHz. The chip is manufactured using the 10 nm SuperFin process.

Performance

The performance of the Intel Core i5-11500B depends primarily on the performance of the installed cooling unit. The TDP of the SoC can also be lowered. In principle, however, the Intel Core i5-11500B should offer slightly more performance than an Intel Core i5-11400H (6 cores 2.7 - 4.5 GHz).

Features

As with the smaller Tiger Lake chips, Wi-Fi (Wi-Fi 6E) and Thunderbolt 4 / USB 4 are (partially) integrated into the chip for faster, cheaper and space-saving implementations in desktops and mini-PCs. The i5-11500B also offers 20 PCIe 4.0 lanes.

Intel Xeon W-11855M

► remove from comparison Intel W-11855M

The Intel Xeon W-11855M is a high end hexa core SoC for laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates six Willow Cove processor cores (12 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 3.2 GHz. The single and dual core boost speed can reach up to 4.9 GHz (using ITBM 3.0), all cores can reach up to 4.4 GHz. The CPU offers 18 MB level 3 cache and supports DDR4-3200 memory.

The Xeon W-11855M is the fastest 6-core CPU of the Tiger Lake line-up at launch and should easily best the older 6 core CPUs thanks to the high clock speeds and the new architecture. Therefore, the Xeon is well suited for even very demanding tasks and is only bested by the 8-core CPUs like the W-11955M.

The SoC also included the improved Xe graphics card called UHD graphics with all 32 EUs.

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.

The chip is produced on the improved 10nm process (called 10nm SuperFin) at Intel, which should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series). The default TDP is rated at 45 W at 3.2 GHz base speed, at 35 Watt the base clock speed decreases to 2.6 GHz (cTDP down).
