Key Takeaway

Initial Linux 7.4 kernel testing on Threadripper 9980X reveals modest performance changes with both small improvements and regressions compared to Linux 7.3 stable.

Summary

Phoronix has published the first round of performance benchmarks for the in-development Linux 7.4 kernel, tested on a System76 Thelio Major workstation equipped with an AMD Ryzen Threadripper 9980X processor. The testing compared Linux 7.3 stable against Linux 7.4 Git as of November 1, using identical compiler and kernel configuration defaults to ensure a fair comparison. Results show limited overall performance gains alongside some small regressions, with CPU power consumption monitored throughout the test suite.

The benchmark coverage spans I/O, graphics, AI, networking, and database workloads, providing a broad view of how the new kernel behaves on high-end AMD workstation hardware. This early testing comes as the Linux 7.4 merge window was winding down, offering developers and users a first look at real-world performance before the kernel reaches stable release.

Benchmark methodology and measured scope

  • Test platform: System76 Thelio Major with AMD Ryzen Threadripper 9980X, 128GB DDR5-5600 (4x32GB), 1TB Crucial NVMe SSD, and Radeon AI PRO R9700 graphics.
  • Kernel versions compared: Linux 7.3 stable versus Linux 7.4 Git snapshot from 1 November 2026, built with identical compiler and default kernel configurations.
  • Power monitoring: CPU power consumption was tracked during all tests, adding energy efficiency data to raw performance metrics.
  • Benchmark categories: Testing covered I/O, graphics, AI, networking, and database workloads across five pages of results.
  • Result pattern: Findings include some performance improvements alongside small regressions, with no large systematic gains over Linux 7.3.

Why it matters

For Linux distribution maintainers and workstation users running Threadripper-based systems, these early results suggest Linux 7.4 will not deliver dramatic performance leaps over 7.3 on AMD's high-end desktop platform. Kernel developers may use this baseline to identify and address regressions before release, while system administrators can set appropriate expectations for upgrade planning on similar HEDT deployments.
