Intel Xeon W-11855M vs Intel Core i9-11950H vs Intel Core i5-11260H
Intel Xeon W-11855M
► remove from comparisonThe 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).

Intel Core i9-11950H
► remove from comparisonThe Intel Core i9-11950H 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. Compared to the i9-11980HK, the 11950H offers professional management features like Intel vPro, SIPP or TXT.
Thanks to the new Tiger Lake architecture, the i9-11980HK should be significantly faster than the old Intel Core i9-10980HK (Comet Lake-H, 2.4 - 5.3 GHz, 16 MB L3) in single and multi threaded performance and similar to the Ryzen 9 5980HX (Zen 3, 3.3 - 4.8 GHz, 16 MB L3). Therefore, the i9 should be one of the fastest laptop CPUs in 2021 and well suited for even very demanding tasks.
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 65 Watt the base clock speed increases to 3.3 GHz (cTDP up).

Intel Core i5-11260H
► remove from comparisonThe Intel Core i5-11260H is a mid range 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 2.6 GHz. The single and dual core boost speed can reach up to 4.4 GHz, all cores can reach up to 4 GHz. The CPU offers 12 MB level 3 cache and supports DDR4-3200 memory.
Thanks to the new Tiger Lake architecture, the i5-11260H should be able to reach the level of the high clocked Intel Core i7-10850H (Comet Lake-H, 6 cores, 2.7 - 5.1 GHz, 16 MB L3) in single and multi threaded performance. Compared, to current AMD offerings, the 11260H should perform similar to a Ryzen 5 5600H (6 cores, 2.4 - 3.3. GHz, 16 MB L3 cache) or the 5600HS when the TDP is set to 35W.
The SoC also features a much improved UHD Graphics (16 EUs) iGPU based on the Xe architecture.
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 in 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 2.6 GHz base speed, at 35 Watt the base clock speed decreases to 2.1 GHz (cTDP down).
