Each virtual machine has a standard virtual hardware configuration for chip set, BIOS, ports, and so on. The amount of memory and number of processors depends on your Mac.

One virtual processor on a host system with one or more logical processors

Up to 32 virtual processors, depending on the available processors on your Mac, virtual machine hardware version, and guest operating system support

The following configurations have two logical processors:

A multiprocessor Mac with two or more physical CPUs

A single-processor Mac with a multicore CPU

Intel 440BX-based motherboard

NS338 SIO

82093AA IOAPIC

PhoenixBIOS 4.0 Release 6 with VESA BIOS

Up to 128 GB, depending on the available memory on your Mac, virtual machine hardware version, and guest operating system support

Total memory available for all virtual machines is limited only by the amount of memory on the Mac

Note

If you assign too much memory to your virtual machines and have them all running at the same time, your Mac might slow down because of heavy disk swapping. As a best practice, make sure the total memory that Fusion and all running virtual machines use stays below 70 percent of your total Mac memory.

128 MB 3D accelerated video with DirectX 9.0c with Shader Model 3 and OpenGL 2.1 for Windows XP as the guest OS

256 MB 3D accelerated video with DirectX 9.0EX with Aero and OpenGL 2.1 for Windows Vista and later as the guest operating system

3D accelerated video with DirectX 11 with OpenGL 4.1 for Windows 7 and later as the guest operating system. DirectX 11 requires macOS 10.15 or later on the host and hardware version 18 and later. You can enable DirectX 11 on the following Mac models

MacPro 2013 and later

iMac 27-inch 2014 and later

MacBook Pro 13-inch 2015 and later

MacBook Pro 15-inch 2015 with dual graphics and later

MacMini 2018 and later

To use the GL_EXT_texture_compression_s3tc and GL_S3_s3tc Open Graphics Library (OpenGL) extensions in a Windows XP or Windows 7 or later guest operating system, you must install Microsoft DirectX End-User Runtime in the guest operating system. OpenGL is an application program interface that is used to define 2D and 3D computer graphics. You can download Microsoft DirectX End-User Runtime from the Microsoft Download Center website.
