购买了新的DELL精密7920工作站，Windows 10 Pro，64位，1803，For Workstations。 （功率设置为“终极”）决斗Intel Xeon Gold 6152,2.1GHz，3.7GHz Turbo 22C（88个超线程逻辑处理器）Benched标志着我们现有的DELL精密7910工作站，Windows 7 Professional，64bit。 （3岁电脑）双Intel Xeon处理器E5-2697 v3,2.6GHz，3.6GHz Turbo 14C（56个超线程逻辑处理器）使用的软件是PTC Creo（4）CAD / CAM。这使用单个线程来计算工具切割器路径，并在进行凿孔检查时使用多线程（所有逻辑处理器）。Xeon Gold的单线程性能，没有看到这个速度超过2.8GHz（不如预期的3.7GHz），比E5-2697慢了67％。多线程，Windows 10“Affinity”使两个处理器组“组0”和“组1”，每组44个逻辑处理器。只能一次激活一个组，并且只能用44个逻辑处理器（而不是总共88个）进行检查，这比E5-2697慢357％。再一次没有看到Xeon Gold的速度超过2.8GHzE5-2697（Win 7）有一组用于处理器关联，所有56个逻辑处理器都被勾选。我尝试将环境变量“处理器数量”更改为88，在计算机重新启动时，它会自动更改回44。有人可以帮忙吗？有没有人遇到这种性能下降的问题？是否有我错过的Windows 10设置，我可以设置单个组的亲和力或提高处理器速度？是否有硬件设置或BIOS设置来提高处理器速度亲和力组？请参阅附件工作站详情戴尔精密工作站7920＆amp; 7910.docx 14.7 K.以上来自于谷歌翻译以下为原文Purchased a new DELL precision 7920 work station, Windows 10 Pro, 64bit, 1803, For Workstations. (power setting is "Ultimate")Duel Intel Xeon Gold 6152, 2.1GHz, 3.7GHz Turbo 22C (88 Hyper threaded logical processors) Benched marked this against our existing DELL precision 7910 work station, Windows 7 Professional, 64bit. (3 years old computer)Dual Intel Xeon Processor E5-2697 v3, 2.6GHz, 3.6GHz Turbo 14C (56 Hyper threaded logical processors) Software used is PTC Creo (4) CAD/CAM.This uses a single thread for calculating tool cutter paths, and multi threads (all logical processors) when gouge checking. Xeon Gold single thread performance, did not see this speed go above 2.8GHz (not 3.7GHz as expected), ran 67% slower than E5-2697.Multi threading, Windows 10 "Affinity" made two processor groups "group 0" & "group 1", with 44 logical processors per group.Can only activate one group at a time and can only gouge check with 44 logical processors (not the total 88), this ran 357% slower than E5-2697.Once again did not see Xeon Gold speed go above 2.8GHz E5-2697 (Win 7) has one group for processor affinity with all 56 logical processors ticked. I tried changing the environment variable "number of processors" to 88, upon computer restart, this automatically changes back to 44. Can anyone help?Has anyone experienced this reduced performance issue?Is there a windows 10 setting that I have missed that I can set affinity to a single group or increase processor speed?Is there a hardware setting or bios setting to improve processor speed affinity group?
