Recently [ETA Prime] felt a bit underwhelmed by the uncooked efficiency of his MacBook Neo when it got here to operating for prolonged intervals below full load, corresponding to when gaming. Thus the apparent answer is to mildly over-engineer a cooling solution that takes care of points like thermal throttling.
The Apple MacBook Neo with its repurposed iPhone 16 SoC appears to have leaned onerous into answering the query whether or not a smartphone could be a good common objective private pc. Ignoring the dearth of I/O, it’s general not a nasty SoC for a laptop computer, however like if you attempt to push the CPU and GPU on a smartphone, they do get fairly toasty. Due to the minimalistic cooling answer within the MacBook Neo it’ll simply hit the 105°C thermal throttle restrict.
Technically the ‘heatsink’ for this laptop computer is the aluminium case, because the SoC is coupled through a thermal pad to the case. This doesn’t depart loads of house and the case will warmth soak fairly quick, whereas additionally making retrofitting a cooling answer a problem.
For the following step a thermo-electric cooler (TEC) with built-in water cooling loop was used, which occurred to be a type of overkill smartphone cooling methods that you just’d keep on with the again of the telephone. Here the cooler was connected equally, on to the underside aluminium of the case.
With this answer in place Geekbench 6 outcomes largely confirmed a strong bump for single-core outcomes, whereas multi-core outcomes confirmed diminishing returns. For Cinebench outcomes this gave a 19% enhance over inventory cooling in multi-core and 23.5% for single-core.
Perhaps most attention-grabbing of all was that enjoying a online game for some time with out thermal throttling meant framerates of over 80 FPS as a substitute of hitting that thermal wall with 30 FPS. This reveals simply how a lot efficiency is left on the desk as a result of cooling selections for the system, even with this nonetheless quite inefficient cooling answer.
That stated, this most likely isn’t some sort of nefarious scheme by Apple, however quite the results of designing the thermal answer to not warmth the case as much as temperatures which are deemed to be unsafe or uncomfortable for the person. After all, if the case is the heatsink, then you definately don’t wish to really feel such as you’re actually dealing with one. This is unfortunately the compromise when venting out scorching air is deemed to be an unacceptable answer.
