AMD 4th Gen EPYC "Genoa" To Enjoy Slightly Better Performance With Linux 6.3
www.phoronix.com
AMD's upcoming 4th Gen EPYC "Genoa" processors are expected to benefit from Automatic IBRS, a new feature in the Linux 6.3 kernel. This feature provides better performance than the current Retpolines implementation for mitigating Spectre V2. The Automatic IBRS support is new to Zen 4 processors and will be enabled by default in Linux 6.3. Benchmarks on the AMD EPYC 9654 server processors show the performance improvement with Automatic IBRS. This feature is similar to Intel's Enhanced IBRS and will be available on both client and server CPUs. The patches for enabling Automatic IBRS have been in the works since November and are now being finalized for the upcoming kernel release.

Summary of Reviews
Pros
- High Performance: With 96 cores and 192 threads, the AMD Epyc 9654 is tailored for heavy-duty computing tasks such as 3D rendering, video editing, data analytics, and complex simulations in enterprise-grade servers.
- Energy Efficiency: It dynamically adjusts power consumption based on workload demands.
- Enhanced Security: Features like Automatic IBRS improve performance while maintaining robust security against vulnerabilities like Spectre V2.
- Broad Compatibility: Optimized performance with upcoming Linux versions (specifically noted with Linux 6.3).
Cons
- Cooling Requirements: Advanced cooling solutions like liquid or advanced air cooling are necessary due to the high thermal design power (TDP) of 360W.
- Overinvestment for Gamers: While capable of high-end gaming, its design and cost are overkill for this purpose, making mainstream processors a more economical choice for gaming.
Best Use Cases
- Ideal for Workstations and Servers: Best suited for environments that require intense computational power and can benefit from its multitasking capabilities.
- Not for Casual Use: Not recommended for users with basic computing needs due to its advanced features and higher cost.
Conclusion
The AMD Epyc 9654 is a powerhouse suited for professional environments that demand extensive multitasking and high computational throughput. Its architecture promises significant improvements in speed and efficiency for supported applications, particularly on newer Linux distributions. However, potential buyers should consider the total cost of ownership, including the necessary cooling systems and whether the high performance specs align with their actual computing needs, especially outside of professional or industrial applications.
