By community request, we present our findings on how the AMD Ryzen 9 3900X performs with SMT disabled. This approach has potential, especially for gaming, because it ensures more physical hardware units are available for each thread, and could also benef

smt off可能是..但是大多评测都是单纯开关smt做对比,却没有对关闭smt后额外的超频空间做进一步的对比分析。我捡到的是一颗天雷37x,smt on的情况下只能1.4v 4.225。关闭之后可以1.425v (镇楼图主

than gaming, and so losing half the threads in Game Mode might actually be a detriment to a workstation implementation. That being said, users can leave SMT on and still change the memory access mode on its own, although AMD is really focusing more on the Creator and Game mode ...
比上面这些都更加重要的是,Zen支持同时多线程(SMT)。几乎核内所有资源都可被“竞争性共享”,也就是说在没有第二个线程的时候,第一个线程通常可以占用全部的运行资源。指令发送遵循循环制,所有周期轮流在轮流的线程上运行。SMT带来的收益因情况而异。Cinebench显示启用SMT带来了良好的提升,跑分高出40%多。然而这...

That being said, users can leave SMT on and still change the memory access mode on its own, although AMD is really focusing more on the Creator and Game mode specifically.For this review, we tested both Creator (default) and Game modes on the 16-core Threadripper 1950X. As an academic ...
