On the GPU side, we lack notable workloads, but GFXBench Aztec High Offscreen ends up with a 56.8W package figure and 69.80W wall active figure. 503.bwaves stands out as having a larger difference between wall power and reported package power – although Apple’s powermetrics showcases a “DRAM” power figure, I think this is just the memory controllers, and that the actual DRAM is not accounted for in the package power figure – the extra wattage that we’re measuring here, because it’s a massive DRAM workload, would be the memory of the M1 Max package. In multi-threaded scenarios, the package and wall power vary from 34-43W on package, and wall active power from 40 to 62W. 511.povray is mostly core-bound with little memory traffic, package power is reported less, although at the wall again the difference is minor. The package and active power are higher than what we’ve seen on the M1, which could be explained by the much larger memory resources of the M1 Max. The actual CPU cluster is only using around 4-5W under this scenario, and we don’t seem to see much of a difference to the M1 in that regard.

It’s possible the software is over-reporting things here.

In single-threaded workloads, such as CineBench r23 and SPEC 502.gcc_r, both which are more mixed in terms of pure computation vs also memory demanding, we see the chip report 11W package power, however we’re just measuring a 8.5-8.7W difference at the wall when under use. One should probably assume a 90% efficiency figure in the AC-to-DC conversion chain from 230V wall to 28V USB-C MagSafe to whatever the internal PMIC usage voltage of the device is. The AC wall power under idle was 7.2W, this was on Apple’s included 140W charger, and while the laptop was on minimum display brightness – it’s likely the actual DC battery power under this scenario is much lower, but lacking the ability to measure this, it’s the second-best thing we have. This is extremely low compared to competitor designs, and is likely a reason Apple is able achieve such fantastic battery life. Starting off with device idle, the chip reports a package power of around 200mW when doing nothing but idling on a static screen. Of course, there’s still an actual average power draw figure when under different scenarios, which is what we come to test here: As long as temperature is kept in check, the silicon will not throttle or not limit itself in terms of power draw. We repeat the exercise here for the 16” MacBook Pro, focusing on chip package power, as well as AC active wall power, meaning device load power, minus idle power.Īpple doesn’t advertise any TDP for the chips of the devices – it’s our understanding that simply doesn’t exist, and the only limitation to the power draw of the chips and laptops are simply thermals.

Since then, we learned how to read out Apple’s individual CPU, GPU, NPU and memory controller power figures, as well as total advertised package power. Last year when we reviewed the M1 inside the Mac mini, we did some rough power measurements based on the wall-power of the machine. Power Behaviour: No Real TDP, but Wide Range
