mac-m4pro.metal14 vCPU · 48 GiB
mac-m4pro.metal

The mac-m4pro.metal pairs 14 vCPU with 48 GiB of RAM, the 3.43 GiB-per-vCPU ratio that marks a general-purpose instance. It runs on Apple silicon M4 pro at 4.5 GHz, and AWS introduced it in September 2025. Rackspace Spot has no equivalent to offer: macOS licensing ties these instances to Apple hardware, which Rackspace Spot does not operate. Spot's largest VM tops out at 16 vCPU and 128 GiB, and even that is not the missing piece here. The table below prices what AWS charges; the honest answer on the Spot side is that this workload stays where it is.

Match qualityNo equivalent

mac-m4pro.metal runs macOS on Apple hardware, which is the entire point of it. Apple only licenses macOS to run on Apple machines, so no cloud provider can offer it as a VM on their own servers. Rackspace Spot has no macOS product and will not have one.

Rackspace Spot sells x86_64 Kubernetes nodes up to 16 vCPU, plus one NVIDIA A30 GPU class. If this is running an Xcode or iOS build pipeline, the macOS steps have to stay where they are — but the Linux parts (dependency caching, container builds, test matrices, publishing artifacts) can move, and on most iOS pipelines that is the larger share of the bill.

When to use it
Good for
  • ●Queue workers and scheduled jobs
  • ●Web and application servers with mixed CPU and memory demand
  • ●Microservices and container fleets
  • ●Workloads that fit inside 48 GiB of RAM
  • ●Jobs that want 1 × 1,900 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at 10 Gigabit
Avoid if
  • ●The working set needs more than 48 GiB of RAM
  • ●You cannot rebuild x86-only binaries or vendor images for aarch64
  • ●You need dedicated hardware. Rackspace Spot sells virtualised compute only.
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
  • ●More than 3.43 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●GPU or FPGA acceleration is needed
Rackspace Spot sells spare capacity at market prices. You pay what the market decides, not a list price.
  • 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.
