Armari’s lower-cost system is something of a technology showcase, exhibiting the latest options in processor, graphics and storage. The combination is one of the most powerful workstations you could buy for £4,500 inc VAT.
At the center of the Magnetar MC16R7 is AMD’s range-topping Ryzen 9 7950X. This potent 16-core processor uses AMD’s latest Zen 4 architecture and is manufactured on the 5nm process. This enables an incredible base clock of 4.5GHz, which is the boost clock for AMD Ryzen Threadripper Pro processors. The 7950X’s boost clock of 5.7GHz is only a few hundred megahertz behind the best Intel has to offer, and only with the latter’s P-cores, so it’s good to see that Armari makes the most out of the Ryzen 9 via its own customized CPU liquid cooling.
Armari has also taken full advantage of the fact that the AMD Ryzen 7000 series supports DDR5 memory by supplying 64GB of 6,000MHz RAM in two 32GB modules, leaving two DIMM slots free for upgrades. This is the fastest-clocked memory of any system this month.
So the Magnetar MC16R7 has a cutting-edge processor, some of the fastest system memory available, and its graphics acceleration is bleeding edge, too. In the past, choosing AMD professional GPUs might be a good choice to keep within a budget, but it rarely beat the Nvidia alternative for performance. The AMD Radeon Pro W7800 is a different matter. It’s in the same price category as the Nvidia RTX A5000 and offers 4,480 unified shaders (which aren’t equivalent to CUDA cores) on AMD’s latest RDNA 3 architecture. It also boasts 32GB of GDDR6 memory on a 256-bit bus, offering 576GB/sec bandwidth.
Armari is notable in the UK market because it’s one of the few local PC integrators that designs its own chassis. However, these cases come at a premium so the Magnetar MC16R7 has been built into a Fractal Design Meshify 2. This is still a great basis for a workstation, with plenty of room inside for airflow and storage upgrades. There are six spaces for 3.5in or 2.5in drives included, and there could optionally be up to 14. On top of this there are two 2.5in-only spaces as standard, but up to four are possible.
You may want to build upon the single M.2 NVMe SSD Armari supplies, but what a great foundation it provides. It’s a 2TB Crucial T700 drive, which supports PCI Express 5, as does the Asus ProArt B650-Creator motherboard. The Crucial SSD delivers incredible throughput from a single drive. CrystalDiskMark recorded sustained reading at 12,373MB/sec and writing at 11,807MB/sec, which were close to twice as fast as some of the PCI Express 4 NVMe SSDs in other workstations this month.
Considering all the powerful components in the Magnetar MC16R7, it’s no surprise that it produced some stunning test results. Our media-focused benchmarks are the Intel Core i9’s forte, but the Armari system’s overall result of 772 is still incredible, significantly beating the other system this month based on an AMD Ryzen 9 7950X. Its Cinebench R23 multithread rendering result of 38,611 was the fastest in the £4,500 category, and the Blender rendering time of 265 seconds was also top in this class. The OpenCL-accelerated Adobe Media Encoder time of 105 seconds beat every other system this month.
The AMD Radeon Pro W7800 graphics may be around the same price as Nvidia’s RTX A5000, but its performance with SPECviewperf 2020 v3.1 is in a different league as well. The results of 235 in 3dsmax-07 and an unbelievable 846 in maya-06 imply this will be a consummate accelerator for 3D animation. Likewise, 155 in catia-06, 235 in creo-03, 622 in snx-04 and 460 in solidworks-07 show strong abilities with product development, CAD and engineering.
Its LuxMark 3.1 result of 14,919 is a little behind the RTX A5000, but GPU rendering in Blender took just 141 seconds, which is ahead.
Overall, the Armari Magnetar MC16R7 provides the best possible performance for the money in most areas. If you need a powerful all-round workstation, this system should be top of your list.
