Eav4 and Easv4-series
The Eav4-series and Easv4-series utilize AMD's 2.35Ghz EPYCTM 7452 processor in a multi-threaded configuration with up to 256MB L3 cache, increasing options for running most memory optimized workloads. The Eav4-series and Easv4-series have the same memory and disk configurations as the Ev3 & Esv3-series.
Eav4-series sizes are based on the 2.35Ghz AMD EPYCTM 7452 processor that can achieve a boosted maximum frequency of 3.35GHz and use premium SSD. The Eav4-series sizes are ideal for memory-intensive enterprise applications. Data disk storage is billed separately from virtual machines. To use premium SSD, use the Easv4-series sizes. The pricing and billing meters for Easv4 sizes are the same as the Eav3-series.

Size table definitions
Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.
Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.
If you want to get the best performance for your VMs, you should limit the number of data disks to two disks per vCPU.
Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth.
Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
