![]() ![]() ![]() I have some doubts that i9s in particular are a good processor for anything that pushes the cpu into much of a sustained load in any laptop or if fan noise is an issue - they’re also battery eaters, even more so than the i7 in my MBP, which I think of more as a portable computer than a laptop for hours of use running on the battery.Just like a turbo engine has "turbo lag" due to the time it takes for the turbo to spool up, I'm curious what is the "turbo lag" in Intel processors.įor instance, the i9-8950HK in my MacBook Pro 15" 2018 (running macOS Catalina 10.15.7) usually sits around 1.3 GHz when idle, but when I run a CPU-intensive program, the CPU frequency shoots up to, say 4.3 GHz or so (initially). One of my nephews recently had an i9 gaming PC laptop for his birthday and it runs like a little with the fans whining away all the time. It took a big heatsink with two big fans plus two big case fans to get the temperature and fan noise down to acceptable levels. The hottest-running cpu I’ve personal experience of was a Pentium D which ran really hot while using much more power than any quad core i7 and had a lower thermal limit and no ability to self-throttle. The i9 is also touted by Intel as a kind of cheaper alternative to the Xeon W range, the Xeons being designed to run hard for hours at a time without problems while the i9 is more intended for applications that sometimes benefit from the extra speed but where it still gets lots of time at or close to idle - unlike the cpu in a DAW that has to run a low audio buffer and do a lot of thread processing non-stop. The question is whether the cpu/gpu routinely gets so hot it starts to self-throttle. I9s do seem to run quite hot, which implies their power usage maybe isn’t as efficient as would be ideal but they are what they are and it’s unlikely Intel, Apple or any other manufacturer with a reputation to worry about would knowingly build products that overheat. Polycarbonate cased PCs often have very poor internal cooling, but you don’t feel it because the case doesn’t get hot, just what’s inside it. A MacBook case is actually a decent heatsink - a heatsink that doesn’t end up get somewhere near to the temperature of what it’s attached to isn’t working properly. iPads and iPhones use their aluminium alloy backs as heatsinks and get quite warm sometimes. Macbooks have used the big lump of aluminium they’re machined out of as a heatsink for many years. I have a feeling the whole laptop body is now part of the heatsink so it's designed to just get hot. It’s also worthwhile checking the design thermal limit of the processor in question, though I suspect it’s higher than you’re seeing. Intel’s power gadget is useful for monitoring temperatures if you’ve not downloaded it. a polycarbonate PC laptop, especially in the area around the cpu/gpu. MacBooks use the solid aluminium block they’re machined from as a heatsink so the user tends to notice heat more than from e.g. It also has to be said that the i9 MBPs do have a reputation for generally running a bit on the hot side, and Live for whatever reason puts more strain on the cpu generally than does e.g. ![]() Before I reduced Live’s frame-rate it was getting hotter than that as the Intel graphics struggled to keep up with the demand. ![]() My i7 MBP typically hits around 60-65 degrees, mostly because the audio driver immediately pushes one core into Turbo mode and holds it there, which is still below where the cpu self-throttles. There’s a thread in the “tips and tricks” section of the forum which might help with that, try searching it for “Windowserver”. It’s possibly a side-effect of how Live 10 hits some Mac’s Windowserver system leading to it running the gpu absolutely flat out all the time. ![]()
