VMWare Fusion vs VirtualBox CPU consumption

I’ve used both Fusion and VirtualBox extensively in the past, and after swapping over to VMWare Fusion Free Personal edition, I’ve discovered something quite interesting.

My Current settings:

VirtualBox:

VirtualBox Graphical User Interface
Version 6.1.18 r142142 (Qt5.6.3)

VMWare Fusion:

Player Version 12.1.2 (17964953)

Using VirtualBox on my MacMini 2018 (3.2 GHz 6-Core Intel Core i7) with 64GB of RAM, I was finding it was producing a small amount of thermal throttling and can bring the temperature up to about 90 degrees celcius at times. While this isn’t super hot, it borders on what the MacMini likes, and so fans kick in.

My previous 4,1 MacPro used to handle the temperatures fine with no thermal throttling, however, this new MacMini performs better giving the higher CPU and SSD performance, and with lower power consumption.

However, the biggest thing is CPU usage when Windows is idle.

VirtualBox sits at about 180% CPU

Whereas VMWare sits around 60% CPU usage

AUDIO WORKS

The other big thing is that the sound works in VMWare Fusion, whereas I couldn’t get audio to work properly in VirtualBox on a Windows 10 VM with MacOS 11.2.3 as the host. This is the real game-changer.

One problem I do have is that Windows in VMWare won’t boot up with the Network device attached. I have to Disconnect Network Adapter” before it boots, otherwise it hangs before the login screen.

The network is fine.

Update:

After my initial VM was loaded, I found that somehow it had become corrupted, and that Windows 10 simply wouldn’t boot – even after all of the windows boot fixes and restores I could find. Strangely, my data was still good and I was able to get it all back using EFSExplorer, which can read virtual drives. Seriously, if you have any virtual machines running critical data on them, it’s a must and a no-brainer.

Supported virtual technologies:
VMware VMDK, Hyper-V VHD/VHDX, QEMU/XEN QCOW/QCOW2, VirtualBox VDI, Apple DMG, Paralles, EnCase E01 and Ex01 non-encrypted files, simple disk images

Anyway, after a complete reinstall, instead of an import from a previous VBox image, I’ve had no issues at all – including that network problem earlier.
