The Intel NUC 11 Pro is small, and that makes it exciting. While we generally review hardware that is designed to meet TCO metrics, the NUC is different. This device is, let us face it, designed to also be fun. Intel NUCs in this type of form factor has been around for a while, and despite the ominous “Tiger Canyon” codename (after all, who would want to walk through a canyon filled with hungry tigers?), this is actually a fun little node. This is not just because it has a 10nm SuperFin Tiger Lake processor in it. In our review, we are going to see why.

Intel NUC 11 Pro (NUC11TNKi5) Overview

The system itself is a relatively compact unit, with a huge asterisk next to it. We will get to the asterisk later, but the unit measures 112mm x 117mm which is around 4.5 inches.

On the front of the unit, we have a power button along with two USB Type-A ports. These are USB 3.2 Gen2 ports which means they operate at 10Gbps.

Moving to the rear of the unit, we have a fairly full I/O panel. There are two HDMI 2.0b ports. Many other nodes in this class have at least one DisplayPort so this is a bit different. One also gets a USB 2.0 port and a USB 3.2 Gen2 port each in Type-A form factors. The Type-C ports are interesting. They are listed as USB 4 / Thunderbolt 4 and 3 ports. This is a massive amount of USB connectivity in such a small chassis.

Another big feature is the Intel i225-lm networking. With this generation, we get 2.5GbE. Although it is a single port, having faster Ethernet is a big deal for many. We get comments on the availability of 2.5GbE switches, but Rohit has two fairly reasonably priced units in his review pipeline. The switch situation will get better this generation as 2.5GbE becomes more prevalent. Even the Supermicro X12SCA-F we reviewed this week has a 2.5GbE port.

On the sides, we simply have vents for cooling.

The plastic top of the system can be removed. This however only exposes a metal airflow guide as well as WiFi antenna wiring. It is not much here.

Removing the bottom cover involves four screws, one in each rubber foot. As we take the cover off, we notice that inside the NUC we get several thermal pads to keep components such as the M.2 SSD cool.

Inside the system, we see a packed set of components. Standard we get a WiFi 6/ Bluetooth solution in the Intel AX201 NIC.

There are then two M.2 slots. One is a M.2 2242 (42mm) SATA III/ PCIe Gen3 x1 slot which is designed for boot devices. The other is a M.2 2280 (80mm) PCIe Gen4 x4 slot. That means one can install both a boot drive in the M.2 2242 slot as well as have high-performance M.2 storage in the x4 slot.

In terms of memory, we get two 1.2V DDR4-3200 SODIMM slots. We added two 32GB SODIMMs and the system had no issue running with 64GB of memory.

Perhaps one of the biggest features is the CPU. This system has an Intel Core i5-1135G7 CPU. While this is a lower-power four core/ 8 thread unit, it also has a new technology in it, specifically the Intel Iris Xe graphics. As Intel begins to re-enter the GPU market after many years, this Xe architecture is designed to scale from this class of chip to the large Ponte Vecchio HPC GPUs for Exascale computing. There, of course, is going to be a fairly massive difference, but Intel is getting back in the running.

The size was mentioned with an asterisk. That is because the power supply is external and is roughly the size of the unit, perhaps a bit larger. At 120W, the 19V power supply is larger than one may need for just the system however this is designed to have headroom for plugging-in higher power USB/ Thunderbolt devices.

Next, we are going to get to the performance, followed by power consumption, noise, our key lessons learned, and then our final words.


  1. It would be nice to include noise measurements for all these compact units using a calibrated decibels meter. The reason is that in many office, home and home-lab environments the noise footprint may be more important than the physical footprint.

  2. Eric, I 100% agree. I had to do this one at my house and between the work they are doing outside landscaping/ cutting down trees this week, and the fact we have other stuff for all of the launches running means the noise floor outside of my office was too loud. The data center does not help with this since that requires ear protection.

  3. Is there a version of this with ECC memory and enterprise management?

    Also, that power brick is bigger than the 200w 19v unit that came with my MSI gaming laptop with an RTX GPU!!!

  4. The big thing that stands out to me is the front doesn’t have the shiny area that hides a CIR interface. Patric, can you confirm if this still has CIR for remote control interfaces like all the previous generations? I have been using NUC’s for HTPC’s and it would suck loosing that.

  5. Would be great to hear the opinion on some of the more powerful vaults ( for a more full featured SOHO firewall router, where more opnsense or untangled extras turned on. A common (seems to me) scenario these days of home network with separate personal, home office, appliances, and guest VLANs.

  6. I have always found the NUC form factor to be interesting, but I have never found it to be practical.

    I believe that there is a bounding limit between physical size, computing power, and heat dissipation that this NUC does not get right.

    No, I’m not one of those “passively cooled PC types that believes in heatsinks in any insane size necessary”. There is another website that specializes in that stuff /facepalm/

    I have a few small passively cooled PCs at home. They all have cases around the size of the Lenovo in the picture, maybe twice as thick/tall. They all work well, but, as expected, they will “thermal out” under heavier computing loads. That is what I have come to expect of the Intel NUC form factor; it cannot dissipate heat fast enough without resorting to active cooling measures that add noise. NUCs are fine, if you don’t push them to the performance levels supported by the higher end processors found in some NUCs.

    And noise you ask? Look at the fans required to cool 1U servers and the speeds they must operate to do that job effective, lest an entire chassis panel be devoted to cooling fans. I refer you back to the recent STH article on the ASRock 1U server. That’s part of the dilemma of reducing size; it limits how much cooling capacity you can achieve without resorting to “mind blowing fan noise” (pun intended).

    I think the Lenovo form factor in the picture is fine and I might be tempted to buy one if I needed one, but not the NUC form factor. Overheating due to poor passive cooling design (air space is required to make it work), or noisy operation due to aggressive active cooling (1U forced-air cooling concept), or thermally limited CPU operation because of issues with either of the former concepts.

    Another issue that has always kept me from considering Intel NUC products has been their use of Realtek NICs rather than their own Intel NICs. Granted, Realtek NICs are decent and very cheep in large quantities, but, they break more than Intel NICs. I have “tossed out” multiple broken Realtek NICs, but I have NEVER HAD AN INTEL NIC FAIL. You would think Intel would be in a position to cut itself a good deal on their own NICs, even a low-end i210 basic Gig-E NIC. BUT NOOO! If I wanted the better NIC in my NUC I would have to fork out for a higher end NUC for a better NIC and risk the previously mentioned issues with heat and thermal limiting.

    Honestly, Intel has proven quite capable of designing very good NICs, much like 3Com (remember them?) did with their family of NICs. Intel can be revolutionary in CPU design, at times, but sometimes they attempt things that are simply too risky in a security sense. How long have network security and firewalls and access controls been around? Since at least the IBM RACF program on mainframes?

    Ok, another good STH review, but this product is not for me. It’s a niche product leveraging technical virtual signalling. It’s a POC product that has outlived it’s time in the marketplace.

  7. I have an “H” series NUC (fits 2.5″ SFF drive) in front of me with Core i7-8650U quad core.

    The fan is nothing short of annoying and I’m not doing much at all with it at the moment. Typing into this comment box and a work VM running in the background. CPU is @ 10% at 2.2GHz.

    The number 1 complaint we’ve had since around the 7th/8th generation NUC with higher end higher TDP CPUs is fan noise. Plus, the top does get quite hot.

    So, we’ve stopped selling anything above a Core i3 that are being used as Windows Remote Desktop terminals and that’s it.

    Small Form Factor like the Tiny makes a lot more sense for higher TDP CPUs that are sensitive to air flow needs.

  8. Sleepy – it’s an Intel nic. Stated on the first page of the review.

    If AX201 is replaced with AX210, would the antenna configuration work well with the added Wi-Fi 6E (and BT 5.2) using 6GHz spectrum or would you need other antennas to be able to take advantage of 6GHz?

  9. Patrick, you might miss the point that you don’t need the power brick if you connect the NUC to a monitor via USB-C connector. In that case this thing is really shining. Very small form factor and excellent IO.

  10. John – this SKU unfortunately seems to lack CIR but there’s other models available with CIR!

    ECC! please pretty please!

    110mm M.2 and PLP…. I can wish…

    storage performance is absolutely what I’m interested in this for because the Xe QS acceleration for transcode jobs and TB4 is suggesting it to me for connecting to a MacBook to assist with video editing work.

  11. EK! Precisely – you have it right there!

    I’m figuring out how this could travel with a M1 MacBook and a monitor and I think it’s looking pretty good despite lacking in my wishes.

  12. There is brief mention of the iris Xe GPU upgrade. A feature that sadly never made it to desktop 11th Gen, yet wasn’t elaborated on any further.
    I’d very much like to move forward with a media library project, but am really trying to go AV1, rather than dealing with H264/265.
    Obviously the streaming/Plex infrastructure isn’t quite there yet, but within the next 2 yrs I’m expecting most streaming devices to support AV1 decode at least.
    My current plan was to rip, and probably transcode with an i9-10900/T/K, depending on pricing, other factors.
    But as AV1 H/W encode isn’t yet supported on anything other than Intel’s discrete GPUs, I don’t expect there to be any diff in perf between 10/11/12/13th gen. Leaving me to potentially pickup a cheap Intel Arc A380 or similar, for transcoding.
    Can you elaborate/confirm any further on iGPU/QSV AV1 performance? Other than decode support, does 11th+ provide any tangible benefit here?
    Also, with Intel depricating SGX support after 10th Gen, effectively killing UHD BD support, I would imagine using 11+ would be more limiting for ripping…

    Love your more enterprise/enthusiast perspective content!
