Windows 11 introduces a refreshed UI and new features, prompting comparisons with Windows 10 regarding system optimization and performance. Performance differences are often hardware-dependent.
General Performance and Resource Consumption
- Windows 11 generally has faster boot times on modern systems with SSDs and UEFI.
- Windows 10 may be snappier on older hardware due to a lighter resource footprint.
- A fresh Windows 10 installation uses ~3.5 GB RAM and ~145 services.
- A fresh Windows 11 installation uses ~5.6 GB RAM and ~165 processes on identical hardware.
- Windows 10 occupies ~38.5 GB storage post-installation; Windows 11 ~54 GB.
- Windows 11's higher baseline usage is due to features like cloud sync, Copilot, modern apps, and enhanced security. Systems with 8GB RAM or less may experience slowdowns.
CPU, GPU, and Storage Performance
Marginal to no significant differences in general application performance between Windows 10 and 11 on Intel 10th/11th Gen Core processors.
- Some tests show Windows 10 favoring CPU usage and application performance, with Windows 11 often exhibiting higher idle CPU activity.
- Windows 11 is designed for better workload distribution across CPU cores, benefiting multi-threaded applications.
- Windows 11 shows improvements in random read/write storage performance.
- DirectStorage in Windows 11 allows GPU decompression of game data for faster loading and higher frame rates with NVMe SSDs.
- Windows 11 has enhanced HDD handling with Storage Sense and background defragmentation, but SSD upgrade is highly recommended.
Gaming Performance
Many games show similar frame rates across both OS.
- Windows 11 gaming enhancements: Auto HDR (improved visuals), DirectStorage (accelerated loading on NVMe SSDs), and advanced DirectX 12 Ultimate support (ray tracing, variable rate shading).
- Virtualization-Based Security (VBS), including Memory Integrity (Core Isolation), in Windows 11 can cause performance degradation (7-9% frame rate reduction in memory-sensitive scenarios). VBS is often enabled by default in Windows 11, but disabled in Windows 10. Disabling VBS in Windows 11 can equalize or slightly surpass Windows 10 gaming performance.
- Recent benchmarks indicate Windows 10 is consistently faster than Windows 11 in some game titles (e.g., Cyberpunk 2077, Starfield) by 2-11%, even with VBS disabled on Windows 11.
Power Efficiency and Battery Life
Initial reports suggested Windows 11 might drain laptop batteries faster.
- Microsoft claims Windows 11 is designed for extended battery life through optimizations and efficient updates.
- Windows 11 includes "Energy recommendations."
- Testing yields varied results: some show Windows 10 with better battery life (e.g., 11% uplift under stress, 35 mins longer video playback), while others show similar or slightly improved battery life on Windows 11 with newer hardware.
Optimization Strategies in Windows 11
- Disable Startup Programs and Background Apps.
- Adjust Visual Effects (deactivate animations, transparency).
- Update Windows and Drivers.
- Utilize Game Mode.
- Set Power Mode to "High performance" (may impact battery).
- Manually adjust Virtual Memory (paging file).
- Use Efficiency Mode in Task Manager for background applications (use with caution).
Conclusion on Windows 10 vs. 11
Windows 11 offers modern features but demands higher system resources. Performance differences are often negligible or slightly favor Windows 10, especially on older hardware or with VBS enabled in Windows 11. Modern systems with sufficient resources and VBS disabled can leverage Windows 11's advantages. SSD upgrade is crucial for both, especially Windows 11.
