System76 unveils ARM Ampere Altra workstation
System76, purveyor of Linux computers, distributions, and now also desktop environments, has just unveiled its latest top-end workstation, but this time, it's not an x86 machine. They've been working together with Ampere to build a workstation based around Ampere's Altra ARM processors: the Thelio Astra. Phoronix, fine purveyor of Linux-focused benchmarks, were lucky enough to benchmark one, and has more information on the new workstation.
System76 designed the Thelio Astra in collaboration with Ampere Computing. The System76 Thelio Astra makes use of Ampere Altra processors up to the Ampere Altra Max 128-core ARMv8 processor that in turn supports 8-channel DDR4 ECC memory. The Thelio Astra can be configured with up to 512GB of system memory, choice of Ampere Altra processors, up to NVIDIA RTX 6000 Ada Generation graphics, dual 10 Gigabit Ethernet, and up to 16TB of PCIe 4.0 NVMe SSD storage. System76 designed the Thelio Astra ARM64 workstation to be complemented by NVIDIA graphics given the pervasiveness of NVIDIA GPUs/accelerators for artificial intelligence and machine learning workloads.
The Astra is contained within System76's custom-designed, in-house-manufactured Thelio chassis. Pricing on the System76 Thelio Astra will start out at $3,299 USD with the 64-core Ampere Altra Q64-22 processor, 2 x 32GB of ECC DDR4-3200 memory, 500GB NVMe SSD, and NVIDIA A402 graphics card.

This pricing is actually remarkably favourable considering the hardware you're getting. System76 and its employees have been dropping hints for a while now they were working on an ARM variant of their Thelio workstation, and knowing some of the prices others are asking, I definitely expected the base price to hit $5000, so this is a pleasant surprise. With the Altra processors getting a tiny bit long in the tooth, you do notice some oddities here, specifically the DDR4 RAM instead of the modern DDR5, as well as the lack of PCIe 5.0.
The problem is that while the Altra has a successor in the AmpereOne processor, its availability is quite limited, and most of them probably end up in datacentres and expensive servers for big tech companies. This newer variant does come with DDR5 and PCIe 5.0 support, but doesn't yet have a lower core count version, so even if it were readily available it might simply push the price too far up. Regardless, the Altra is still a ridiculously powerful processor, and at anywhere between 64 and 128 cores, it's got power to spare.
The Thelio Astra will be available come 12 November, and while I would perform a considerable number of eyebrow-raising acts to get my hands on one, it's unlikely System76 will ship one over for a review.
