I'm looking for a new PC notebook with low DPC latency for realtime audio.

A few month ago I bougt an MSI Raider GE76 (12th gen i7) but this thing is too high on DPC latency, audio crackling everywhere even when tuning down CPU power to avoid CPU throttle.

A real nightmare.

Do you have a recent notebook PC with LOW DPC latency, enabling realtime audio without any problem ?

I'd like to find a 17 inches screen with 2500x1440 res, 12th gen i7, 32go ram, 1to SSD.
It's not for gaming so GPU is not a priority here.

Any brand I can look for ?

You can test your DPC Latency with Latencymon, a free tool is available here : https://www.resplendence.com/latencymon
(it has to run at least for 5-10 minutes to give real results)

Thanks for any input !

Apart from the basics you can do (disable the power management and set the highest performance mode in windows), what driver is actually causing the DPC spikes?

It's usually networking (disable that for testing) or graphics (update drivers of course). Also if you have a lot of USB gear hooked up try removing those to see if one might be the culprit.

My laptop knowledge is a few years out of date here, but I've a had no issues with Lenovos or HPs. Dells on the other hand have always been flaky.

If you can't get the information from here, or Google (which is down to pure luck) then reddit's r/laptops is a decent place to ask as well: https://www.reddit.com/r/laptops/

 

Seems that most 12th gen intel with gaming GPU are way too problematic with thermal issues to avoid DPC latency.

Even when setting very low values to PL1 / PL2 in bios or XTU/ThrottleStop doesnt help that much ... audio clicks are less frequent but still there.

And 12th gen intel without gaming GPU are hard to find.

Even companies who are selling pro-audio orientated laptops didnt know about DPC latency problems ...

The editors describe the test circumstances in detail, but most testers only run LatencyMon for a few minutes. Furthermore, there are models in the list whose values in the ranking do not match the values determined in the individual test. I hope that this still helps you with a rough orientation.
