m6in.4xlarge

m6in.4xlarge is AWS's general-purpose EC2 size at 16 vCPU and 64 GiB. In the name, "m" is the general-purpose line, "6" is the generation, "in" marks Intel processors and enhanced networking and "4xlarge" is the size within the m6in family. It runs on Intel Xeon 8375C (Ice Lake) at 3.5 GHz, and AWS introduced it in November 2022. AWS has since shipped m7i, m8in and m9g; m7i.4xlarge is the direct replacement at this size, scoring 372,382 CoreMark/s against this instance's 266,867 — roughly 40% more throughput for the same vCPU count. On Rackspace Spot the same shape is gp.vs2.2xlarge — 16 vCPU, 64 GiB, matched on both dimensions, $1.11/hr on AWS in US East (N. Virginia), from $0.041/hr on Rackspace Spot.

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 64 GiB of RAM
  • ●Parallel work that can occupy 16 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 50 Gigabit
Avoid if
  • ●Starting a new deployment. m7i.4xlarge is the newer generation at this size.
  • ●The working set needs more than 64 GiB of RAM
  • ●The work is single-threaded. Most of these 16 vCPU would sit idle.
  • ●Local NVMe or instance-store disk is a hard requirement
  • ●GPU or FPGA acceleration is needed
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
Stop overpaying AWS. This compute costs $813/mo on AWS vs $30/mo on Rackspace Spot.
  • 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.
