Intel Xeon W-11855M

英特尔至强W-11855M是笔记本电脑和移动工作站的高端Hexa核心SoC。以Tiger Lake H45一代为基础，2021年中期发表。内置6个Willow Cove处理器核心（Hyper支持12个线程）线程化）。基本时钟速度因TDP设定而异，45瓦特为3.2GHz。单核和双核升压速度最高可达4.9GHz（使用ITBM 3.0），所有核心最高可达4.4GHz。 CPU提供18MB级3高速缓存，支持DDR4-3200内存。

Xeon W-11855M是Tiger Lake系列产品中最快的6核CPU，时钟速度快，结构新颖，可轻松超越旧6核CPU。因此，Xeon非常适合要求苛刻的工作，仅适用于W-11955M等8核CPU。

此外，SoC还配备了改进的Xe显卡，称为UHD显卡，适用于所有32个EUHD显卡。

此外，Tiger Lake SoCs还增加了PCIe 4支持（H45系列20通道）、AI硬件加速、Thunderbolt 4/USB 4和Wi-Fi 6E部分集成到芯片中。

芯片在英特尔改进的 10nm 工艺（称为 10nm SuperFin）中生产，与 TSMC 的 7nm 工艺（例如，Ryzen 4000 系列）相同。默认 TDP 额定值为 45W，基本速度为 3.2GHz，基本时钟速度为 35W，降至 2.6GHz（cTDP 下降）。
