Ryzen AI Halo Review: AMD's DGX Spark And Mac Mini Challenger Tested
AMD Ryzen AI Halo Thermal, Acoustic, and Power
when idle, the Ryzen AI Halo is silent, draws little power, and feels cool to the touch. So while our Local AI Bench pass ran (which is a 90-minute torture test) we had plenty of opportunity to monitor power consumption, listen to fan noise, and monitor temperatures both inside and out. About 45 minutes into our run, we took all three measurements in a quiet room with an ambient temp of 22°C, or 71°F.As you can see above, at the rear vents of the system 12 inches away, we measured 45 dBA. That's really minimal sound pressure, all things considered. You'll never put your head 12 inches from the rear of the system under normal use, and that's the loudest part of the Ryzen AI Halo. So it's quiet under duress, which we like quite a bit.
Surface temperatures are excellent. Touch anywhere on the system while it's running and it's barely warmer than ambient. Only where the exhaust exits the system do we see any temperature above 32-33°C. The 46°C we measured for exit temps is warm to the touch but it won't hurt your sensitive fingers. Plus it's not a laptop, so even if it did get warm, it's not an issue.
And at idle, power consumption is very low. It just sits around 33-35 Watts while nothing is going on. Power draw spikes under load, and we saw spikes up to 150 Watts, which we couldn't quite catch on camera. We did catch 147 Watts as seen above. Normally it hovered between 135 and 145 Watts. The Ryzen AI Max+ 395 has a maximum TDP in this system of 120 Watts, and there's an external USB-C Power Delivery AC adapter, so all of this seems like what one might expect.
Internally, the story is excellent. The above image is a photo of the monitor running on AMD Software's performance metrics tab. We can see with a full GPU load that the system drew (according to these internal metrics) nearly its full 120 Watt rating, which is the max officially supported by this chip. Yet, it was still well under what we'd consider a high temperature. Sure, 76°C is quite a bit warmer than ambient temp, but the Ryzen AI Max+ 395 has a Tjmax of 100°C and we're well below that. The cooler in this system does a great job. Just don't cover the vents.
So let's break in and see how it works. First, the feet are magnetic which is a joy. It's so aggravating when you take apart a small PC and the adhesive on the rubber feet covering the screws is gone. Here the magnet feet pry right up.
Back out four long screws with a JIS1 screwdriver head (Philips #0 would also work) and then the bottom lifts right off.
Now you've got access to the SSD, which is easy to change out. Let's take a closer look at it...
This is a PCIe Gen 5 SSD from Micron, which earlier this year went OEM-only when it axed the Crucial brand. This is a Micron 4600 specifically, with 2TB of capacity.
Then things start to get tricky. We had to remove a small plate covering the Wi-Fi and Bluetooth antennas and pop those off their standard snap-in posts, and also disconnect a ribbon cable attached to the side of the machine which goes to the power button (which is not part of the motherboard for repairability's sake, we imagine, since buttons can break) along with a two-pin header that drives the LEDs.
With all of that lifted out of the way, including some adhesive on the power ribbon cable, we could finally lift the motherboard free from its case. The old adage is, if it fights you, don't fight back. There are no screws to remove beyond what we've already covered. It just lifts out, so if it doesn't just lift out you're probably yanking on a cable.
And here's our first good look at that cooler with two relatively large blower fans made by Delta. Let's take another angle to see that heatsink in all its glory.
The all-copper cooler is massive compared to the rest of the machine, but honestly, that's why the Ryzen AI Halo stays so cool and quiet under load. AMD engineered it for long-term use, and it shows.
We could have gone farther, but at this point I chickened out and didn't want to break something. Putting the system together is just reversing these steps. Slide in the motherboard, reattach the antennae and two other connectors, then slap the bottom back on and screw it in. Those magnet feet went in just as they were designed.
AMD Ryzen AI Halo Thoughts And Conclusions
As the cost of cloud AI services skyrocket and subsidy funding dries up (both OpenAI and Anthropic have implemented dramatic price increases over the last couple of months), we think more people will turn to localized solutions for running AI models. That's exactly what the Ryzen AI Halo is built for, and exactly the market AMD is targeting with the product. It has gobs of fast memory and enough compute performance to keep many relatively large models running at reasonable speeds. The comparisons against NVIDIA's DGX Spark kind of write themselves, and AMD's little box holds its own.Let's start off by looking at the competition. After Apple's price increases at the end of June and, to a lesser extent, NVIDIA's own price increases earlier in the year, the Ryzen AI Halo is actually the most affordable system of this type you can get with 128GB of RAM. So even though it wasn't the absolute fastest in many of our tests, it's competitive with the DGX Spark from NVIDIA in many scenarios, and it's less expensive which enhances its value further. If I was buying a system to be a home server running something like GPT-OSS 120B, AMD's Ryzen AI Halo would be at the top of my list.
Also, having the choice of Linux and Windows is a huge bonus. While the Ryzen AI Halo isn't a gaming PC, it could pull double duty and play the latest games too, thanks to AMD's solid graphics drivers. And it would make one heck of an everyday PC too. We didn't take time to do much in the way of gaming or productivity tests today, but with its 120 Watt TDP, it should perform better than the ASUS ROG Flow z13 or HP's ZBook Ultra G1a we evaluated recently. It's certainly quieter and runs cooler as well.
There are a couple of downsides to the first Ryzen AI Halo, though. First of all, the company already announced a follow-up Ryzen AI Halo with the Ryzen AI Max+ 495 CPU when it debuted this model back in May. AMD didn't say when this version would launch, but it will sport up to 192GB of LPDDR5x. While 128GB is pretty spacious for many models today, having room to grow would be nice, especially considering how fast LLMs tend to grow over time. Second, if you're on the other end of the spectrum and don't need quite so much RAM, the M4 Max Mac Studio is generally faster running most models, and though it has a current 64GB ceiling, it's a couple hundred dollars cheaper, too.
On the developer side, AMD is clearly headed in the right direction and has done some great things, but there's more work to do. AMD provides the Ryzen Developer portal and it has a lot going on for it. However, there's more breadth in the competition's documentation, as we discussed earlier. Multi-node options are also limited with the Ryzen AI Halo, as it's tough to keep up with the DGX Spark's 200 Gbps ConnectX NIC over QSFP. While the Ryzen AI Halo is a solid competitor for many use cases now, we're hoping AMD pushes the envelope when the 192 GB model based on the Ryzen AI Max+ 495 ships.
As of this moment in July of 2026, however, AMD has the least expensive 128GB compact AI workstation available on the market, and it's got a lot going for it. Its performance is roughly on par with the DGX Spark with many models, and its software platform flexibility is great. As cloud AI costs keep rising, many users are going to turn to local solutions. If that describes you, the Ryzen AI Halo should be high on your list of local AI workstation considerations. For its excellent build quality and design, flexible software options, and competitive performance, the AMD Ryzen AI Halo easily earns a HotHardware Recommended award.
