Compute-optimized virtual machine (VMs) instances are ideal for customers most performance-intensive workloads. Compute-optimized VMs are built on architecture that utilizes features like non-uniform memory access (NUMA) for optimal reliable uniform performance.
This machine family is built on the 2nd Generation Intel Xeon Scalable processor (Cascade Lake) offering up to 3.8 GHz sustained all-core turbo clock speed. Compute-optimized VMs offer the highest consistent performance per core to support real-time application performance.
C2 VMs provide full transparency into the architecture of the underlying server platforms, letting you fine-tune the performance. C2s offer much more computing power, and are generally more robust for compute-intensive workloads compared to N1 high-CPU machine types.
C2 VMs come in different machine types ranging from 4 to 60 vCPUs, and offer up to 240 GB of memory. You can attach up to 3TB of local storage to these VMs for applications that require higher storage performance.
C2 VMs produce a greater than 40% performance improvement compared to the previous generation N1 machines and offer higher performance per thread and isolation for latency-sensitive workloads.
C2 enables the highest performance per core and the highest frequency for compute-bound workloads using Intel 3.8 GHz Cascade Lake processors. If you are looking to optimize workloads for single thread performance, particularly with respect to floating point, use C2 in order to leverage AVX512 capabilities only available on Intel.

*A vCPU is implemented as a single hardware Hyper-thread on one of
the available CPU platforms.
†Persistent disk usage is charged separately from machine type pricing.
‡Maximum egress bandwidth cannot exceed the number given. Actual egress bandwidth depends on the destination IP address and other factors. See Network bandwidth.
C2 VMs have the following restrictions:
- You cannot use regional persistent disks with C2s.
- C2s are subject to different disk limits than general-purpose and memory-optimized VMs.
- C2s are only available in select zones and regions on specific CPU processors.
- C2s do not support GPUs.
