'FX' family general purpose VM size series
Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets
The 'FX' family of VM size series are one of Azure's specialized compute-optimized VM instances, designed primarily workloads that require significant CPU capabilities. These VMs use the latest Intel Ice Lake processors and are optimized for compute-intensive tasks such as financial modeling, scientific simulations, and heavy calculations. With a high frequency and a large cache per core, FX-series VMs provide exceptional computational power, making them ideal for scenarios demanding extensive processing resources and rapid execution of complex operations.
Workloads and use cases
Electronic Design Automation (EDA): FX-series VMs are well-suited for EDA workloads, which require high CPU clock speeds and high memory-to-CPU ratios. These workloads benefit from the high single-core performance and large memory capacity of FX-series VMs.
Batch Processing: FX-series VMs are excellent for high-throughput batch processing jobs, such as those involving large-scale data analysis and transformation, where rapid processing is critical.
Data Analytics: FX-series VMs are suitable for intensive data analytics applications, especially those that require quick iteration and processing of large data sets.
Series in family
FX-series
The FX-series runs on the Intel® Xeon® Gold 6246R (Cascade Lake) processors. It features an all-core-turbo frequency of 4.0 GHz, 21 GB RAM per vCPU, up to 1 TB total RAM, and local temporary storage. The FX-series will benefit workloads that require a high CPU clock speed and high memory to CPU ratio, workloads with high per-core licensing costs, and applications requiring a high single-core performance. A typical use case for FX-series is the Electronic Design Automation (EDA) workload. FX-series VMs feature Intel® Turbo Boost Technology 2.0, Intel® Hyper-Threading Technology, and Intel® Advanced Vector Extensions 512 (Intel® AVX-512).
