Dv3 and Dsv3-series
The Dv3-series run on Intel® Xeon® Platinum 8272CL (Cascade Lake), Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors in a hyper-threaded configuration, providing a better value proposition for most general purpose workloads. Memory has been expanded (from ~3.5 GiB/vCPU to 4 GiB/vCPU) while disk and network limits have been adjusted on a per core basis to align with the move to hyperthreading. The Dv3-series no longer has the high memory VM sizes of the D/Dv2-series, those have been moved to the memory optimized Ev3 and Esv3-series.
Example D-series use cases include enterprise-grade applications, relational databases, in-memory caching, and analytics.
Dv3-series sizes run on Intel® Xeon® Platinum 8272CL (Cascade Lake), Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors with Intel® Turbo Boost Technology 2.0. The Dv3-series sizes offer a combination of vCPU, memory, and temporary storage for most production workloads.
Data disk storage is billed separately from virtual machines. To use premium storage disks, use the Dsv3 sizes. The pricing and billing meters for Dsv3 sizes are the same as Dv3-series.
Dv3-series VMs feature Intel® Hyper-Threading Technology.

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).
