MiTAC G8825Z5 Power Consumption
In terms of power, we did not have this hooked up to our standard monitoring at the PDU. At the same time, you can see a few interesting things from the telemetry data provided by the machine itself.
Keeping the GPUs in the 36-40C range at idle is actually a great result. Here we can see one of the challenges with big systems like this with the eight GPUs using over 1kW of power at idle, and with the potential to hit 8kW just for the GPUs under load. In air-cooled systems, that does not include cooling, or the 1kW of CPUs, and often 1kW+ of other components. Plus a large amount of cooling. It is not uncommon for these systems to use 12kW when under full loads.
STH Server Spider: MiTAC G8825Z5
In the second half of 2018, we introduced the STH Server Spider as a quick reference to where a server system’s aptitude lies. Our goal is to start giving a quick visual depiction of the types of parameters that a server is targeted at.
Here we have a server that is designed for AI compute and also HBM3E memory. With 8U of rack height, MiTAC also managed to fit 12 PCIe slots meaning this has enough expansion capacity for a lot of networking as well.
Final Words
Overall, the construction of this system is really neat. The dual zones with a GPU tray and a CPU/ PCIe tray helps with maintaining the system. It also helps keep the system cool during operation. With eight AMD Instinct MI325X GPUs with 2TB of combined HBM3E memory this has a lot of power for AI.
This system was actually a fairly early MI325X system when we saw it running in January 2025, but it was great to see. AMD has made great strides in making its GPUs more competitive over the past few quarters, and with larger models and a bigger focus on inference, this is an interesting system.
Overall, the MiTAC G8825Z5 was executed quite well. For those who want simplified mantenance, having all front I/O with only power supplies and fan modules at the rear will be an attractive option as well.
Great deep dive into the MiTAC G8825Z5. The tray-based serviceability and redundant PSU setup are impressive, especially for dense GPU workloads. It is fascinating how designs like this balance airflow and expansion. Thanks for the detailed breakdown.
Roughly, how much would this beast cost?
(I know, I know, if you have to ask…)
@TurboFEM: I’ve been debating about buying a house in La Jolla, CA, or just keeping my apartment in Akron, OH . . . in the end, it’s really not a difficult choice, as I don’t need to move ;)
All well and good, but will it run Crysis?

*How many 4K instances of Crysis can this run?
Nice write-up Patrick!
BTW, what tool do you use to display the PCIe topology like that?

That is the lstopo command
default output is graphical, but there is also an ASCII output.
