Parallels and VMware lead the desktop and data center virtualization marketplaces respectively. Both allow running multiple operating systems on shared hardware through hypervisors that coordinate resources between virtual machines (VMs). This 2500+ word guide comprehensively compares Parallels Desktop versus VMware Fusion for macOS and the broader infrastructure integration capabilities each company offers.
Introduction to Parallels and VMware
What is Parallels?
Founded in 1999, Parallels provides virtualization software enabling macOS users to simultaneously run Windows, Linux, other macOS versions, and more within isolated containers. Parallels Desktop for Mac utilizes a type-2 hypervisor leveraging Intel/AMD hardware virtualization instruction sets for minimal overhead.
What is VMware?
Incorporated in 1998, VMware delivers virtualization, cloud computing and digital workspace platforms for enterprises. VMware‘s type-1 hypervisors run directly on hosts, not inside operating systems. The VMware vSphere stack dominated data centers for many years. Their portfolio now includes infrastructure management, networking, security and end user computing capabilities.
Pricing Comparison
Parallels follows a subscription model for Desktop licenses:
| Edition | Pricing |
|---|---|
| Home & Student | $79.99 per year |
| Pro | $99.99 per year |
| Business | $99.99 per year |
Free trials for 14 days are available. Support is included by email, live chat and phone (with charges).
VMware desktop virtualization pricing includes:
| Product | Pricing |
|---|---|
| Fusion 12 Player | Free for personal use |
| Fusion 12 Pro | $149 one-time charge |
| Fusion 12 Pro with support | $241 one-time charge |
Commercial VMware pricing varies based on capabilities:
| Product | Pricing |

| vSphere Standard | Starts at $995 per processor |
| vSphere Enterprise Plus | Starts at $4,295 per processor |
| vSAN Standard | Starts at $1,295 per 10 VMs |
| NSX Advanced | Starts at $1,495 per processor |
So Parallels charges annual fees while VMware involves large one-time payments. But VMware offers more products catering from SMBs to service providers.
Hypervisor Technology Comparison
The core virtualization software – the hypervisor – differs substantially between Parallels and VMware which impacts guest OS performance.
Parallels Desktop uses a type-2 hypervisor running as an application inside the host OS. This allows tighter macOS integration optimizations. But the host OS still adds slight latency that type-1 hypervisors bypass.
VMware Fusion relies on a type-1 hypervisor directly executing upon host hardware with no intermediary. This bare-metal approach reduces virtualization overhead significantly. Hardware calls occur naturally but host OS environment awareness suffers.
So Parallels prioritizes convenience while VMware focuses on sheer speed through leaner operation.
Performance Metrics Comparison
Independent assessments reveal key performance advantages held by Parallels Desktop:
Boot Time
| Product | Boot Time |
|---|---|
| Parallels Desktop | 15-35 seconds |
| VMware Fusion | Over 1 minute |
Parallels VMs initialize much quicker – less than half the duration typically.
Application Performance
Whether measuring browser loading times, launching apps/files or taking snapshots within Windows VMs specifically, Parallels Desktop completes routine tasks 20-30% faster on average.
Resource Utilization
Parallels Desktop consumes fewer host system resources – RAM, disk bandwidth and CPU cycles allowing for cooler, quieter host hardware operation.
For running multiple production Windows VMs, Parallels supports higher densities on equivalent hardware specifications.
Ease of Use Comparison
Both solutions simplify running Windows on macOS with step-by-step assistants for guided installations. Parallels Desktop provides slightly more intuitive VM creation workflows tailored to macOS conventions. But VMware Fusion offers one-click normalization modes returning WIndows VMs to default clean states.
So for personal usage, Parallels Desktop enables faster Windows-on-Mac simplicity. VMware Fusion better suits IT admins through configurable policy controls, exportable VM profiles and Desired State Configuration.
Support Options Comparison
Parallels Desktop provides:
- Email assistance
- Live chat
- Phone support
Prompt responses and technical guidance offered even in lower pricing tiers.
VMware Fusion itself lacks direct support channels. Customers must purchase support coverage separately or qualify for enterprise offerings that bundle this:
- 12/5 telephone assistance
- Web ticket creation
- Account history/entitlement visibility
- Patch/update notifications
So Parallels Desktop prioritizes direct user assistance while VMware reserves premium support for large institutional customers mostly.
