What we should point out here, however, is that power profiles that dictate system performance when plugged in or on battery power are not completely up to AMD. What's Really Going On With Intel's Findings? ![]() Intel Thinks That AMD Is Up To Some Funny Business With Ryzen 4000U ![]() So, what's behind AMD's seemingly masterful execution of top-notch performance while maintaining enviably low power consumption on mobile platforms? Intel sought to answer this question as well and performed its own internal tests on five Ryzen 4000U Series notebooks and compared them against similar systems with its own Tiger Lake processors installed. Intel has countered AMD's Ryzen 4000 family with its 11 th generation Tiger Lake processors with integrated Iris Xe graphics, but even current quad-core CPU models aren't enough to tackle AMD's high-end Ryzen 4000U configurations that top out with 8-core/16-thread SKUs. Needless to say, AMD's rise is coming at the expense of Intel, which has long dominated in the laptop sector. And while Ryzen 4000 graphics performance won't knock your socks off, the integrated AMD Radeon Vega GPU can also handle some light gaming workloads. Mpbfan is installed and running but fans are idle most of the time. So it doesn’t make sense the Bios is sending the signal, right? I’m running now with ignore_ppc in grub, /sys/module/processor/parameters/ignore_ppc showing ‘1’ value persistently. This is the output of lm-sensors right at the moment when CPU speed falls down to 798MHz. But I hope it’s something simpler.Īny ideas on how to diagnose this? Any information or test commands will be of enormous help. So my interpretation is that the temp readings are not accurate, which makes fans not blow enough, and the CPU is self-triggering a throttle to protect itself. If I shutdown the computer the fans start blowing at max. speed of 1.6GHz will not prevent it from throttling down to 798MHz anyways. The journal doesn’t show any events when the throttle happens, unless I am missing some parameters. Only a reboot is taking it out from there. measured temperature at the moment (psensor) was is 74☌ (GPU).ĬPUs which run at the same hardware frequency: 5ĬPUs which need to have their frequency coordinated by software: 5Ĭurrent policy: frequency should be within 800 MHz and 3.70 GHz.Ĭurrent CPU frequency: 798 MHz (asserted by call to kernel) The governor “performance” may decide which speed to useĬurrent CPU frequency: Unable to call hardwareĬurrent CPU frequency: 1.60 GHz (asserted by call to kernel)įive minutes later, while playback on a video editor, the mysterious throttle happens. speed to 1.6GHz with cpupower, this is the initial info I get.ĬPUs which run at the same hardware frequency: 3ĬPUs which need to have their frequency coordinated by software: 3Īvailable cpufreq governors: conservative ondemand userspace powersave performance schedutilĬurrent policy: frequency should be within 800 MHz and 1.60 GHz.

I was suspicious of a recent update, maybe changes on applesmc or coresmc. I don’t know what is calling the action, but it happens each time the CPU is somewhat pushed to a heavy load for a while. Recently my laptop is getting stuck at minimum CPU speed (798MHz). ![]()
