ROG Zenith II Extreme Motherboard Power Consumption
Power consumption can vary a significant amount depending on processors used and the number of HDDs/SSDs/Expansion cards used. Here we test just a primary system. We test with the same graphics card and NVMe SSD in all our tests. Power is measured at the wall and the graphics card and SSD were not stress tested.
For our tests, we use the AIDA64 Stress test which allows us to stress all aspects of the system. The ROG Zenith II Extreme and AMD Ryzen Threadripper 3970X is a power-hungry platform and in this case. It has the highest idle power use of 130watts. Full stress tests generate a 424watt pull at the wall power use. Although this is high, it is actually less than we saw with the previous generation 32-core AMD Ryzen Threadripper 2990WX chip which is impressive.
The ASUS ROG Zenith II Extreme Motherboard and AMD Ryzen Threadripper 3970X sure is one platform to take a serious look at for workstation duties. It surpasses even dual-CPU Intel Xeon platforms in many ways. If you recall back when the first-gen Threadripper came out many had issues with inter die memory latency issues which forced us to turn off hyperthreading for some applications. As we have seen with the closely related AMD EPYC 7002 series, the previous generation oddities with NUMA domains is gone.
The ROG Zenith II Extreme Motherboard did not leave us wanting, stability was right on with no crashes of any kind. With the feature loadout, you can connect just about anything form fans to water cooling systems. It is built to handle just about anything. With the ROG Dominus Extreme aside, the ROG Zenith II Extreme Motherboard is one of the heavest motherboards we have used to date. All of the aluminum heat sinks and rolled steel backplate no doubt make the platform feel substantial.
ASUS kept its ROG DIMM.2 M.2 expansion device which only holds 2x SSDs. Other motherboards are coming with a PCIe card that can hold 4x M.2 drives which might work out better for some users. Scattered across the face of the motherboard are two extra M.2 slots between the PCIe slots. The M.2 slot on the motherboard’s underside is a very curious inclusion. On a motherboard like the Intel Xeon LGA3647-based mITX ASRock Rack EPC621D4I-2M underside M.2 slots make sense. There is no other space with the severely constrained mITX form factor. With E-ATX, this seems like less of a necessity. On the other hand, it is there which is better than not having a 5th M.2 slot.
At the time of this writing, the ROG Zenith II Extreme motherboard has an $849 street price. Add in the $1,999 for the AMD Ryzen Threadripper 3970X or $1399 for the 24-core 3960X and this is not a budget workstation platform. At the same time, when it is competing and winning against the Xeon W-3275 at $4449 just for the CPU, it looks more reasonable. One does not get the same 1TB of memory support with the Threadripper, nor ECC RDIMM support for inexpensive 32GB modules. Still, the pure speed, lower cost, and PCIe Gen4 offer a compelling reason for many to forego higher ECC RDIMM memory capacities if they are not absolutely needed. It is strange to think, but at $2850 for the CPU and motherboard, it has a compelling performance case at closer to half the cost of the Intel Xeon W-3275 solution. Perhaps that makes an $850 motherboard a bargain even though it feels strange to suggest that.
Overall, if you are looking to build an ultimate AMD Ryzen Threadripper workstation, the ASUS ROG Zenith II Extreme motherboard is perhaps the top platform out there to build upon.
