Intel Core i5-11400H vs Intel Xeon W-11955M vs Intel Core i5-11500B

Intel Core i5-11400H

The Intel Core i5-11400H is a high-end hexa-core SoC for gaming 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 2.7 GHz. The single core boost speed can reach up to 4.5 GHz, all cores can reach up to 4.1 GHz. The CPU geatures 12 MB L3 cache and supports DDR4-3200 memory.

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 SoC features an improved Gen 12 graphics adapter called UHD Graphics with 16 EUs.

Performance

The average 11400H in our database matches the Ryzen 5 5600U and the Core i7-10750H in multi-thread performance, rendering the Core i5 a decent mid-range option as of mid 2022. It isn't as fast as the mighty Ryzen 9 5900HS, yet it will let you run most games in High or even Ultra settings at 1080p if mated to a fast graphics card.

Thanks to its decent cooling solution and a long-term CPU power limit of 45 W, the Gigabyte G5 GD (2021) is among the fastest laptops built around the 11400H that we know of. It can be around 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 series chip has a default TDP of 35 W to 45 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, an active cooling solution is a must for a CPU like this.

The i5-11400H is manufactured on Intel's 3rd generation 10 nm process marketed as SuperFin for below average, as of early 2023, energy efficiency.

Intel Xeon W-11955M

The Intel Xeon W-11955M is a high end octa core SoC for laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.6 GHz. The single core boost speed can reach up to 5 GHz (ITBM 3.0, also two cores), all cores can reach up to 4.5 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. Similar to the Core i9-11950H, the Xeon W-11955M supports SIPP, vPro and TXT. In addition to this, the Xeon line supports ECC memory.

Performance

The average W-11955M in our database is in the same league as the Ryzen 7 4800H, Core i7-11850H, Core i7-1360P, as far as multi-thread benchmark scores are concerned. This is a fairly fast chip, as of early 2023.

Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.

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.

Power consumption

This Xeon series chip has a default TDP, also known as the long-term power limit, of 35 W to 45 W, the expectation being that laptop makers will go for a higher value to get better performance.

The W-11955M is built with Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.

Intel Core 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.
