Ubuntu squeezes more performance than Windows 11 on new AMD Zen 4 Threadripper

Original Article ↗ Hacker News Discussion ↗

Benchmarks showing Ubuntu outperforming Windows 11 on AMD’s new high‑core‑count Threadripper CPUs spark broader comparisons between the two platforms for heavy workloads like 3D rendering, compilation, and scientific computing. Commenters attribute Linux’s edge to AMD’s close tuning of the kernel and lower OS overhead, while pointing to Windows Defender, NTFS, and legacy baggage as potential bottlenecks. Many argue, however, that raw performance is secondary to software availability (e.g., Adobe, games), driver support, and usability, which still keep most creatives and enterprises anchored to Windows despite steady improvements in the Linux desktop.

Performance differences and possible causes

  • Many report Linux (Ubuntu, Fedora, etc.) consistently outperforming Windows 10/11 on heavy workloads: 3D rendering, FPGA tools (Vivado), C++ builds, and Blender renders.
  • Suspected Windows bottlenecks: NTFS design vs ext4, filesystem filters, pervasive antivirus hooks (especially Defender), background services, telemetry/indexing, and “bloatware” OEM images.
  • Some note WSL2 and dev-focused features (Dev Drive) use ext4/ReFS and can be faster than native Windows tools on NTFS.
  • A few caution that compiler choice and runtime libraries (e.g., memcpy implementations) could also explain part of the gap; the test setup is not fully detailed.

Who uses high‑end Threadrippers

  • Reported users: VFX and animation studios, 3D rendering farms, ML/CFD/FEA shops, Unreal Engine development, and some boutique workstation vendors.
  • Several say large studios commonly use Linux for rendering and Windows or macOS for creative tools; others claim Windows + Linux now dominate VFX with macOS receding.
  • Some vendors say their Threadripper systems ship with Linux (e.g., Rocky), often headless or with minimal GUI.

Filesystem and build workloads

  • Repeated anecdotes of build times being dramatically faster on Linux or in Linux VMs/WSL2 than on the same hardware under Windows.
  • Windows Defender and other filesystem filters are widely blamed for slow operations on large trees (e.g., node_modules, source trees).
  • NTFS is viewed as mature but constrained by backwards compatibility; ext4/ZFS/Btrfs perceived as more efficient for these workloads.

Desktop experience: Linux vs Windows

  • Split opinions: some find Linux desktops (especially Fedora/Mint/Pop!_OS) more responsive, stable, and under user control; others find Linux brittle, CLI‑heavy, and prone to breakage on updates, with Windows “just working.”
  • Pain points on Linux: graphics driver regressions (especially Nvidia), audio stacks churn, networking (Netplan/NetworkManager/systemd‑networkd), and hardware quirks.
  • Pain points on Windows: forced updates/reboots, ads/telemetry, Defender overhead, and convoluted UI/settings evolution in Windows 10/11.

Packaging, sandboxing, and distributions

  • Strong criticism of Snap (slow startup, odd filesystem behavior, central store lock‑in); mixed but generally more positive views of Flatpak (better but heavy and sometimes poorly sandboxed).
  • Some want a mobile‑style permission model (per‑app access to mic/camera/network/storage); others reject snaps/flatpaks and prefer traditional packages on LTS distros.
  • Distro recommendations diverge: Ubuntu for docs and familiarity; Mint, Fedora, Pop!_OS, and immutable Fedora variants (Silverblue/Onyx/Kinoite) for better UX; Arch/Tumbleweed/Nix for enthusiasts.

Barriers to Linux desktop adoption

  • Key blockers mentioned: Adobe suite, CAD tools, many legacy Windows‑only business apps, anti‑cheat games, and weaker fractional scaling / multi‑DPI support.
  • Enterprise inertia around Excel and Office, plus the diversity of Linux distros, are seen as major organizational hurdles.

Long‑term trajectory

  • Some argue Windows is drifting toward an ad/telemetry platform while core performance and UX stagnate; Linux desktop and gaming support are seen as quietly improving year over year.
  • Others counter that for most non‑technical users, Windows’ app ecosystem, familiarity, and support network still outweigh Linux’s technical and performance advantages.
