Coffee Lake i7 NUC Review (NUC8i7BEH)

Performance and Benchmarks

Installation of Windows 10 on the NUC was simple. The graphics driver version and BIOS version 0048 were used for all the following benchmarks. Even if SimplyNUC delivered the system to me with Team Group RAM, I did swap them with a 2×4 GB HyperX DDR4-2400 CL14 RAM modules ($69.94 on Amazon) as the same modules were used for i3 and i5 testing and I wanted to keep the result comparable.



3DMark is a popular benchmarking suite that benchmarks video and gaming performance of the computer.

In the 3DMark benchmarks we see that the i7 model is 10-15% better than the i5 NUC of the same generation. In general the differences between the Bean Canyon i3, the i5 and the i7 NUCs are pretty small. All NUCs have the same Iris Plus 655 GPU, so in that sense it’s understandable that the results are similar. However, none of the Bean Canyon NUCs are able to come anywhere close to the gaming oriented Hades Canyon NUC (NUC8i7HVK).

Cinebench R15

Cinebench runs 3 separate benchmarks and provides us figures that are comparable between systems. First a simple 3D car chase that measures mainly the GPU (OpenGL) performance. The result is in frames per second. Second there’s a rendering of 3D model with all cores. This stresses purely the CPU. Finally there’s another rendering of the same model, this time using just a single CPU core.

The OpenGL test that stresses mainly the GPU is a similar story again: the results are a bit better on the i7 vs. the i5, but only by approximately 10%.

The CPU benchmark is another story though. The single-core performance of the NUC8i7BEH is the best I’ve ever measured, beating even the NUC8i7HVK (Hades Canyon) and the same is true even for the multi-core benchmark.

Geekbench 3

The Geekbench 3 result is also rather good. Both the single and multi-core results are basically on the same level as the Hades Canyon – even slightly above it. Difference between i5 and i7 stays at approximately 12%. Full Geekbench 3 results are available here.

If you want to compare the detailed results for i5 vs. i7 you can do so here. For those interested, the Geekbench 4 results for the NUC8i7BEH were 5590/18692.

Passmark CPU test

The Passmark test is often used to compare the CPU performance. The score for PassMark CPU performance test was 12547. Here’s a link to the full results.


Using the Intel Extreme Tuning Utility (XTU) you can alter (among other things) the power limits of the CPU package. All the benchmarks above have been taken using the default settings.

However, should you wish to do so, there’s a possibility to configure higher limits for more performance or lower limits for less noise. In the graph above you see the monitoring function of the XTU tool.

  1. I start Prime95 stress test. CPU usage jumps to 100%, core frequency remains high, CPU temperature starts to rise and the fan speed gradually increases.
  2. After approximately 60 seconds, the Turbo Boost period is over and the core frequency is throttled back to a lower level.
  3. At this point I configure the power limits to be significantly higher in the XTU tool. Higher core frequency is used and CPU heats up to 100 degrees Celsius until thermal throttling kicks in and keeps the CPU heat generation (and performance) on a level that the fan manages to keep at a stable albeit high temperature.

Thoughts on Performance

I’ve got a bit mixed feelings regarding the performance. On one hand this NUC has the fastest CPU I’ve ever tested on a NUC when it comes to the raw computing power. On the other hand, the performance is very close to the i5 model that approximately $100/€100 cheaper. The GPU performance is nowhere near Hades Canyon NUC, so this definitely wouldn’t be a gamer’s NUC. Yes, it would be very much capable running some of the even relatively modern games at full HD resolution, but that’s hardly enough for most hard core gamers.

If you’re interested in how this and other Bean Canyon NUCs are doing when playing some games please have a look at a separate article.

So yes, definitely it’s the best performing Bean Canyon NUC as was expected. So in that sense if you’re not concerned about the cost vs. the i3 or the i5 by all means get this one. Personally I think the i5 hits the sweet spot for many use cases, but there’s no argument about the i7 being faster. And as we can see on the next page, it’s not even noisier than the i5.

    All we need now is Akasa case for this 🙂

  2. omnium says:

    If akasa does it like they did in the past, is it at the expense of the NUC8’s small footprint.

  3. beczka says:

    I couldn’t understand from the text which one seems to generate less noise – i5 or i7?
    Did you have the same fan settings in bios?

    • Olli says:

      Sorry, it was a bit late when writing that. 🙂 BIOS settings were on the default settings on both cases and the same BIOS version was used. I think the i5 was somehow more noisy, but the numbers don’t seem to support that. Maybe the noise is just a bit different because of the smaller BEK case vs. the BEH model. I don’t believe that the i5 would generate more heat than the i7. In any case, there’s no big difference. Neither of them is noisy nor quiet.

  4. Mat says:

    How about the possibility of adding an external thunderbolt gpu enclosure with a nvidia 1080 card. Woukd that be enough to turn it into an upgradable games machine?

    • Olli says:

      The CPU is fast, so in theory an external fast GPU will turn the NUC into a mean gaming machine. Never tried that though and couldn’t get anyone to ship me an enclousure…

      • Meghan McCarthy says:

        I am just beginning testing this model with an Aorus Gaming Box, NVIDIA GTX 1080. I can provide an update shortly.

  5. Joe Duarte says:

    Hi Olli – How many PCIe lanes are dedicated to the M.2 SSD?

  6. daas says:

    How long is turbo retained when having power limit increased and cooling preference set to cool instead of balanced or quiet in the bios?

  7. FaceMcBashy says:

    Can you replace the stock thermal compound with some nicer aftermarket ones(not liquid metal) and see if there is any big improvements?

  8. KB says:

    Would you be able to upgrade to future chipsets?

  9. Mac mini 2018 i5 8gb ram 256 disco duro o Nuc8i7beh 16gb ram
    Cual sería mejor? Cual elegirías ? Gracias

  10. Ois says:

    Just ordered mine – I guess I should get a heatsink for the nvme SSD, how much clearance is available above the SSD in the larger case (NUC8i7BEH)?

    • nucblognet says:

      There’s a heat pad included in the NUC kit that will spread the heat from the NVMe drive. I wouldn’t buy anything extra at first unless you’ve got some very specific needs. It’ll probably be just fine without additional heat sinks.

  11. Anders Taranger says:

    Just got the following reply from Akasa:

    Thanks for your inquiry.

    Yes, the Intel NUC8i7BEH Fanless case will be launched around end of Feb..

    Happy days! 😀

  12. Charlie Wolf says:

    I was wondering if you ever made it home as i am wondering when the power consumption report will be up
