265K单线程SPEC IA能效这方面,大核测试出了非常奇怪的曲线,似乎在4.3 - 5.4 GHz之间的电压会偏高,导致曲线凹下去一段。看起来目前电源管理依然不成熟 在最高功耗的区间,LNC单线程展现出了与Zen 4相近的性能与功耗,但是低功耗则与竞争对手渐行渐远 SKM相比RPL的表现与Intel给出的数据基本一致。
私底下聊了会,我大概知道曲线为什么画成这样了,很有趣

14-19W区间的265K确实电压偏高,主板疑似将ring频率定在了最高点,带高整个IA rail电压

在功耗减半的4GHz,缓存延迟敏感的523子项IPC出现cliff,此时大概ring频率终于下降,导致输入电压降低

正常曲线应该是图2紫色这样,不过这并不改变结论

It’s easy to create a Telegram channel via desktop app or mobile app (for Android and iOS): Deputy District Judge Peter Hui sentenced computer technician Ng Man-ho on Thursday, a month after the 27-year-old, who ran a Telegram group called SUCK Channel, was found guilty of seven charges of conspiring to incite others to commit illegal acts during the 2019 extradition bill protests and subsequent months. Matt Hussey, editorial director of NEAR Protocol (and former editor-in-chief of Decrypt) responded to the news of the Telegram group with “#meIRL.”
