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.
