SimplyNUC Onyx v9 Review An Intel Core i9-13900H NUC


SimplyNUC Onyx v9 Performance

Instead of going through the entire Linux-Bench test suite, we are going to show a few performance and power numbers here to give a general sense of performance. This also gives us the opportunity to test with Linux/ Ubuntu instead of just Windows.

Python Linux 4.4.2 Kernel Compile Benchmark

This is one of the most requested benchmarks for STH over the past few years. The task was simple, we have a standard configuration file, the Linux 4.4.2 kernel from, and make the standard auto-generated configuration utilizing every thread in the system. We are expressing results in terms of compiles per hour to make the results easier to read:

Overall one gets a very capable and fast processor with the Intel Core i9-13900H. It is faster than the Core i7, which we would expect. The 14 cores and 20 threads are simply more than AMD’s 8 cores / 16 threads in this segment. Our testing generally works well on heterogeneous cores, but we will quickly note that in some workloads that are really P-core only, AMD can have an advantage.

7-zip Compression Performance

7-zip is a widely used compression/ decompression program that works cross-platform. We started using the program during our early days with Windows testing. It is now part of Linux-Bench.

Still, the big takeaway should be that if you are using this for something like office tasks, there is not a massive gap in performance between this, the Core i7 version, and some AMD options. Bars are longer, but for office applications, the systems will feel snappy. If you used a NUC 10 years ago and found it to be a sub-par experience, today’s NUCs and mini PCs are so fast they provide a great desktop experience.

OpenSSL Performance

OpenSSL is widely used to secure communications between servers. This is an important protocol in many serverĀ stacks. We first look at our sign tests:

Here are the verify results:

As we would expect, the performance is a bit better than the Core i7, as well as the AMD options here.

Geekbench Performance

Just as a quick check versus theĀ Beelink SER7 with the AMD Ryzen 7 7840HS here is what we saw:

The high-end looks fairly similar here so from a CPU performance perspective, we would choose based on whichever GPU and encode/decode version you prefer.

Next, let us get to the power consumption.


  1. You’re right. I’m not sure $999 with those specs and expensive upgrades is good pricing. So I don’t see them targeting consumers

  2. Quick question on the footer of the NUC’s – are the screws connected to the base with metal fasteners (a spring loaded clip)? I really appreciate that there options for a vesa mount but I am limited / unable to mount it as the screws are immovable from the original base so they are not lost.
