Under a constant max power workload I’m certain boost will expire and would assume that it would be for the standard 28s though I do not know the duration for certain. As long as the chip is cool and the power levels have dropped bellow PL1 levels for a few seconds is can boost again but how long will depend on the temp and other boost parameters.
In looking up the 12th gen CPUs the default spec is 28W/64W PL1/PL2 so FW have upped the base and reduced the turbo. In my tests the cooling system can handle 30-32W constant load.
Ultimately I don’t know if there is a test that can achieve what you are looking for, they tend to be stress tests/constant load tests.
Benchmarking is always fun. But I don t understand this wall Cinebench thing…
It looks to me asif there was no more evolution and people are trying to make benches to justify buying a 20 cores laptop !
I have real world usages like :
PLaying a game : this requires 4 P cores (+ good igpu)
Doing video conferencing + many stuf running : 4 P cores + good video live compression/decompression (my 2 cores are not anymore up to the taks)
On a laptop I don t need multi core server tasks or cinebench… I am doing video encoding sometimes. Maybe I am the onlyone.
Concerning turboboost, really its nice, but on my 2 cores 4 years old when they are not fully used, I don t see any slow down, I don t feel my laptop isn t snappy.
Ah, I was thinking would the laptop CPUs follow the desktop CPUs being able to boost indefinitely without a timer. Would love to try cooling it to see if it can maintain boost.
I wonder how it would behave if cooled sufficiently or if there are other power limits put in place. If you do experiment please share, it would be fun to see!
I’m not too sure what you mean but as you may know unlike with desktops laptops with the same CPU and GPU can behave very differently so this is interesting to potential customers of 12th gen and of interest to others. Cinebench or other benches are just a standardised test to allow for direct comparison.
Got my i5-1240P today and ran a couple of quick cinebench checks while plugged in with 76F ambient.
Best Performance mode: 9924 (hit 100C during 60W burst at the start, sustained 32->30W @ 82C)
Balanced mode: 8398 (hit 90C during initial 60W burst, sustained 32->28W @ 80C)
Best Power Efficiency Mode: 5337 (brief 32W, then 18W, then sustained 15W @ ~63C)
Edit: this is both faster and a lot more power efficient than my ryzen 5 3600 desktop, good stuff!
Hows the fan noise and the keyboard temp going? I would suspect that it keeps the same behavior as the 11th but FW may have done something more on the fan profile control.
Normal usage it’s silent and only slightly warm feeling in the center upper part of the keyboard. My CPU temps for light usage sit in the mid 40s celcius with SSD at a similar temp. When it was initially installing endless windows updates or when it was running cinebench it got pretty loud but I think that’s expected.
Edit: The fan does get pretty loud whenever something intense is happening.
It has been reported by notbookcheck that the max laptop noise has doubled. Like 5db more represent twice the noise. Maybe switsh off turboboost?
Now if its just a benchmark stuff …it doesn t really matter
Do you have it when lauching a recent 3d game ?
I just tried planet zoo, and yes the fans are loud (although I’d be shocked if they’re twice as loud as 11th gen, since people complained about noise there too).
Personally I don’t care, it’s silent for normal usage, and ramps up when I push its capabilities - its an ultrabook, seems reasonable. A future version could have some type of beefier dual fan cooling a la the XPS 13 Plus, but it’s not a day to day issue for my use-case.
I completely agree. Looking at the score of the framework on notebookcheck, its one of the best performing laptop with this CPU. If not the king for now !
This means that cooling is appropriate. Now if users want less noise they can set the system to battery saving or deactivate turboboost in BIOS.
This gives a wide variety of setup to fit everyone out there.
It a little misleading for consumers reading the tests out there, max noise perceived by the tester remains in the back of is head when writting the review…because he is lauching stuf like cinebench.
Hi, are you using Windows 10 or 11 for benchmarking? Does Windows 11 has some performance improvement and work better on Intel 12th gen CPU?
Do you suggest using Windows 11 or Windows 10? I saw some reviews online saying that Windows 11 is buggy and not worth upgrading.
Windows 11 has an improved scheduler compared to Windows 10.
The windows 10 scheduler already knows of cores with different performance levels. It can assign the most demanding tasks to the most performant cores. In this regard Windows 11 did not improve, as shown by Gamers Nexus in the pinned video above. The new Windows 11 scheduler takes into account not only the time but also energy needed to complete a task.
The latter part is desirable for Laptops to achieve long battery live and little fan noise.
Anandtech explains the new Alder Lake scheduler here.
