Moonstone R9 - AMD Ryzen 9 - mini pc performance

Read the original post here.


Small systems can evoke endearment. The Moonstone from Simply NUC may look cute, but it can be quite a digital challenge. Simply NUC is a company that, as the name suggests, specializes in the production of mini PCs. Until now, these machines were often based on Intel products. With this Moonstone, however, the brand opts for the red camp. We tested it in a variant based on an AMD Ryzen 9 7940HS. That processor has eight powerful cores that can work on sixteen threads, in combination with an integrated GPU, the Radeon 780M.

When you see the box in front of you, it looks like two drops of water on the nucs based on an Intel processor. That’s not surprising, because just like with a regular desktop, you can simply exchange the motherboard. The housing measures 4 x 4 inches, which is about 10 x 10cm. 

There is also a slot for a MicroSD card.

All connections are within easy reach. On the front you will find two USB-A next to the on/off switch. One is a 2.0 copy, the other runs at 3.0 speed. On the back you will find two HDMI, a fixed 2.5-gigabit network connection, another USB-A 3.0, and two USB 4 in the C version. There is also a slot for a MicroSD card built in on the side. 



As mentioned, the heart of this model is the AMD Ryzen 9 7940HS. That is a chip that rolls off the 4nm production line at TSMC. It is equipped with eight Zen4 cores and falls in the 45W class. The cores can work on two threads simultaneously. The processor also has a built-in Radeon 780M GPU with twelve CUs (768 shaders). This ensures graphic performance. The AMD CPU works together with DDR5 memory. Our test model was equipped with two Team DDR5-4800 modules of 8GB each. 

All this is combined with an OEM SSD from Kingston. It has a capacity of 256GB and a PCI Express 4.0 interface. You can also choose SSDs and memory with a different capacity via Simply NUC’s configurator. The prices for the larger capacities increase considerably. Simply NUC has installed a large cooling profile to allow the heat to flow away from the SSD. 

A large cooling profile has been fitted for the SSD .

The network facilities are arranged based on Intel products. An Intel AX210 controls WiFi and supports up to the 6E standard. The network port is also based on Intel and offers a speed of 2.5 gigabit. The system is supplied with a large 120W/19V power supply block. When idle the Moonstone consumes about 7 to 8 watts, under load this increases to an average of 68 watts, with peaks above 80 watts.



If we compare this Simply NUC with the previously tested Intel NUC 13 Pro based on Raptor Lake, an interesting picture emerges. In 3DMark, the AMD-based Simply NUC is much faster, but in PCMark 10 the picture is less clear. In that benchmark, the Simply NUC is faster in a number of tests, while in some other tests the Intel NUC wins. In Cinebench, AMD’s chip is a lot faster in multi-core, but in single-core it is outdone by Intel’s competitor.

Because Simply NUC supplies the Moonstone R9 as a complete system, we also measured the performance of the 256GB SSD. In AS SSD the performance is very disappointing, but in ATTO a score is achieved that is excellent for a PCI Express 4.0 SSD. The throughput speed in the PCMark 10 test is average. All in all, it is not a special SSD. If you are a power user, we would put another one in this mini PC.

The Simply NUC Moonstone R9 CBM3R9MS with a Ryzen 9 7940HS is a very interesting machine. The base is fast and powerful. Because AMD’s processor has eight powerful Ryzen 4 cores on board, combined with the Radeon 780M, this is truly a small bomb. 

That bomb is ideally suited for relatively heavy tasks. Of course, the first thought that comes to mind is to use it as a desktop. If you are really demanding, we would replace the built-in SSD with a faster one.

The basis is very interesting, partly thanks to the AMD chip, but also because of the excellent connectivity, with USB 4, 2.5 gigabit Ethernet and Wi-Fi 6E. In short: there is little left to be desired. However, the device is not cheap. The configuration we tested, with 16GB DDR5 and a 256GB SSD, costs 1,136.19 euros. It can be purchased through the company’s website.
