Power Consumption and Thermal Characteristics

The power consumption at the wall was measured with a 4K display being driven through the HDMI port of the system. In the graph below, we compare the idle and load power of the Intel NUC13ANKi7 (Arena Canyon) with other systems evaluated before. For load power consumption, we ran the AIDA64 System Stability Test with various stress components, as well as our custom stress test with Prime95 / Furmark, and noted the peak as well as idling power consumption at the wall.

Power Consumption

The numbers are consistent with the TDP and suggested PL1 / PL2 values for the processors in the systems, and do not come as any surprise. The load number is affected by the PL2 value (64W for the Core i7-1360P in the NUC13ANKi7). The idling numbers are excellent, with the low power state achieved by the Arena Canyon NUC matched only by the Wall Street Canyon NUCs.

Stress Testing

Our thermal stress routine is a combination of Prime95, Furmark, and Finalwire's AIDA64 System Stability Test. The following 9-step sequence is followed, starting with the system at idle:

  • Start with the Prime95 stress test configured for maximum power consumption
  • After 30 minutes, add Furmark GPU stress workload
  • After 30 minutes, terminate the Prime95 workload
  • After 30 minutes, terminate the Furmark workload and let the system idle
  • After 30 minutes of idling, start the AIDA64 System Stress Test (SST) with CPU, caches, and RAM activated
  • After 30 minutes, terminate the previous AIDA64 SST and start a new one with the GPU, CPU, caches, and RAM activated
  • After 30 minutes, terminate the previous AIDA64 SST and start a new one with only the GPU activated
  • After 30 minutes, terminate the previous AIDA64 SST and start a new one with the CPU, GPU, caches, RAM, and SSD activated
  • After 30 minutes, terminate the AIDA64 SST and let the system idle for 30 minutes

Traditionally, this test used to record the clock frequencies - however, with the increasing number of cores in modern processors and fine-grained clock control, frequency information makes the graphs cluttered and doesn't contribute much to understanding the thermal performance of the system. The focus is now on the power consumption and temperature profiles to determine if throttling is in play.


The system has no trouble maintaining a 40W package power throughout the loading period. The iGPU seems to have a maximum power budget of around 32W, with 18W being guaranteed even during high CPU load. The package temperature does reach around 92C, but never high enough for throttling to kick in. The SSD temperatures stay below 60C even when the disk is subject to stress.

    NUC are useless. Plastic computers with huge external power supplies yet people are actually trying to defend this shit. There's a reason why PC sales are in the sh***ter. For decades PC fanboys vomited out how much PC they could buy/build for the price we bought our Mac. Now PC aren't even that affordable. I'd rather buy a M2 Mini as well. I got Thunderbolt, easy upgrade to 10G networking. The PC industry is beyond boring right now.

    I think it's funny you think PC sales are being eaten up by macs.
    They're not.
    The largest market share is from smartphones, and it's primarily Android that has been eating Windows PC market share.

    The breakdown of share is basically this
    43.9% Android
    27.7% Windows
    17.1% iOS
    6.2% OSX
    5.1% Other and Unknown

    I don't understand the animosity that exists in the Mac vs non-Mac camps. I have and have used both platforms -- Macs since around 1990 and Windows PCs since around 2002 and continue to use both in my professional career. Each has their place and use cases.

    Just because a product doesn't match your world-view, regardless of which platform you prefer, doesn't make the other worthless or useless.

    Regardless of which platform ultimately takes the performance crown, M2, M2 Pro, etc or Raptor Lake, there's no denying that the various iterations of Apple Silicon have amazing perf/W which is especially beneficial in laptop form-factors. It's also really nice for quiet, high performance computing in small form factors, whether that's a SFF desktop or a laptop.

    That said, there are also advantages to the upgradeability of non-Apple devices. The ability to upgrade RAM or storage down the road, whether due to budget limitations at the original time or purchase, or whether you're taking advantage of lower prices in the future can help REDUCE eWaste by allowing an otherwise adequate machine to continue to be used rather than discarded.
    It doesn't help Apple's case that in addition to being non-upgradeable they DO charge pretty high prices for upgrading RAM or storage on their machines. +$200 for upgrading from 8GB of RAM to 16GB, or from 256GB of SSD to 512GB is pretty steep (especially since Apple is paying bulk prices) when as an individual you can buy either a 64GB DDR4 3200 SO-DIMM kit or 2TB NVMe SSD for less than $150 at retail.

    To directly address the claim that NUCs are useless:
    These aren't designed for your average home user. That's not to say that an average home user can't or shouldn't buy a NUC. But really, one of the major intended audience is big corporate offices where the NUC can be VESA mounted to the back of a display and the power brick can be stashed away under a desk.

    Also, MOST non-Atom/Pentium/Celeron NUCs (including the 13th generation models in this article) have Thunderbolt.

    Circling back to what I hope my key takeaway is:
    Can't we all just agree that we all like tech and that new technology is cool rather than just needing to bash on whoever has a different opinion than us?

    Ditto. I use both. In fact I have an iPhone, iPad, Intel i7 custom-built gaming PC, Ryzen 5600G HTPC for media, 8th Gen Dell Latitude work laptop and my old Macbook Air for when I need OSX for something like testing a clients software. I have a Pixel 3 without cellular connection to fly my drone (because frankly the iPad and iPhone suck for this) and use Android and Raspberry Pi's for projects of all kinds. I've considered getting an M2-based laptop as soon as they are financially viable to replace my aging iPad Pro as my kitchen table media toy.

    This is the definition of a competitive industry benefiting the consumer and pushing technology forward. EVERYTHING HAS ITS APPLICATION.
  • ingwe - Tuesday, March 28, 2023 - link

    Spot on. I also don't understand the need to be a fanboy of these gigantic companies that care nothing for individuals.

    I'm perfectly happy to use whatever fits my application.

    Been building PCs since 1999 and do not recall upgrading any. Once they need more RAM the CPU is also too slow. I replaced HD with SSD many years ago before many people had SSD which was huge upgrade. Still using that PC (2.8Ghz AMD Phenom II)!!!

    I'm pretty sure this is bait, but I'll bite. NUCs are not useless, because NUCs are real computers. Mac minis are gimmick computers more alike to an iPhone than a desktop computer. If you buy a NUC, you can use it to run or host anything you'd like, between multiple operating systems. Yes it matters to me if hardware is supported by Linux or not. You can also upgrade components using industry standard technologies like M.2, SODIMM, SATA. Apple exists in this strange bubble outside the industry and at every single opportunity they will screw over their customers with crazy pricing, hostile repair practices, and expertly designed price brackets designed to cause distress in customers so they just spend $200 more...$200 more...$100 more. Also, I am not sure how you came to the conclusion that PCs are more expensive, as AMD and Intel have caught up to Apple Silicon, and PC manufacturers offer more competitive upgradeable components for a lower cost.

    As a M1 Mac mini owner, been there, done that. There is a lot to like about that computer, but a lot more limitations that make it so infuriating. First, Apple starts those machines at $600 but Apple charges a whopping $200 for an extra 8 GB of ram, which is ridiculous. Then you have to pay $200 extra for 512gb of storage instead of 256gb of storage. Apple's flash isn't even particularly fast, and it is soldered. So all those people that would worry about SSD failure, I hope you are comfortable de-soldering flash. (If such a thing is possible.) Another annoyance is the base configuration with the M2 has a very limited display engine on the GPU, which means you only get two monitors, and the built in HDMI port is more problematic than its worth as it constantly limits resolution, refresh rate, HDR, and variable refresh rate. Perhaps worst of all, the Mac mini comes with macOS and there is no choice to change the operating system, even though there has been some progress on reverse engineering, it is not useful. Running a server or something on a Mac mini is simply painful. I suggest that most people avoid the Mac mini even though the marketing seems appealing.

    My oranges have 64GB of RAM not 8GB, and 2TB of NVMe not 250GB.

    And I use 10Gbit networking via TB, because they run containers and VMs as µ-servers, not sure if Apple allows NICs they don't sell.

    You can't even get 64GB of RAM from a Mini, while it's €120 including taxes on Intel or AMD.

    You fancy 8TB of NVMe next year, no issue swapping the stick, some NUCalikes offer a 2nd slot.

    I seriously wouldn't mind an Apple SoC in my Linux systems, but not with the ballast of MacOS or the prices they charge for meaningful configurations.

    Until the SSD runs out. Apple needs to not make systems that can't swap the SSD and RAM, none upgradeability on the SSD is a deal breaker.
