m8i.metal-96xl

m8i.metal-96xl is AWS's general-purpose EC2 size at 384 vCPU and 1536 GiB. In the name, "m" is the general-purpose line, "8" is the generation, "i" marks Intel processors and "metal-96xl" is the size within the m8i family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in August 2025. AWS has since shipped m9g. Spot's largest VM is 16 vCPU and 128 GiB, so matching this instance would take 24 × gp.vs2.2xlarge — arithmetically true and operationally absurd. The Spot column below prices that whole fleet, so read it as a scale reference rather than a drop-in replacement: at this size the useful question is what a shard of the workload costs, which is $0.041/hr per node.

Match qualityVirtualised, not bare metal

m8i.metal-96xl is a full physical server — no virtualisation layer in the way, direct access to the hardware, and a socket count that licensing can verify.

Rackspace Spot no longer sells bare metal; everything in the catalog is a virtual machine. You get the same cores and memory (24 × gp.vs2.2xlarge, 384 vCPU, 1,536 GiB), but not the dedicated hardware. If you picked m8i.metal-96xl because you needed the real machine — nested virtualisation, per-socket licensing, low-level profiling — this is not a replacement at any price. If you picked it because it is the biggest m8i, it is the same compute for a lot less.

When to use it
Good for
  • ●Development, staging and CI environments
  • ●Small to mid-size relational databases
  • ●Backend services with no single dominant resource
  • ●Workloads that fit inside 1536 GiB of RAM
  • ●Parallel work that can occupy 384 vCPU
  • ●Network-heavy services — AWS rates this size at 100 Gigabit
Avoid if
  • ●The working set needs more than 1536 GiB of RAM
  • ●You need dedicated hardware. Rackspace Spot sells virtualised compute only.
  • ●You want a single-machine Spot equivalent. At this size there is not one.
  • ●More than 4.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●The work is single-threaded. Most of these 384 vCPU would sit idle.
  • ●Local NVMe or instance-store disk is a hard requirement
m8i.metal-96xl is $14,835/mo on AWS on-demand. A gp.vs2.2xlarge node on Rackspace Spot is $30/mo — at this size the per-node price is the honest comparison.
  • Spot sells spare capacity at market prices. It is the cheapest compute on the internet.
  • Prices are set by supply and demand. You pay what the market decides.
  • Compute is delivered as fully managed Kubernetes. All infrastructure is taken care of.
  • Egress costs $0.01/GB after the free allowance. AWS charges $0.09/GB.
