AMD is enhancing the performance of older Ryzen APUs through a new feature called PerfOpt, which boosts AI performance by up to 18-23%.
AMD made a new feature called PerfOpt that makes older AMD Ryzen computers work better with AI. It's like giving an old toy a new trick to make it play better.
Analysis
AMD's IOMMU Performance Optimization Feature
The AMD IOMMU Performance Optimization feature allows the AMD Ryzen SoCs to bypass the IOMMU when directly accessing system memory, reducing overhead. This feature is now enabled by default in Linux 7.4 for Radeon integrated graphics.
Testing with an Older AMD Ryzen 7 PRO 7840U
To demonstrate the impact of PerfOpt, I tested an older Lenovo ThinkPad P14s Gen 4 with the AMD Ryzen 7 PRO 7840U and Radeon 780M integrated graphics. The system was running Ubuntu 26.04 LTS with a kernel build of the IOMMU next Git tree.
Performance Improvements
With PerfOpt enabled, the AI performance on the older AMD Ryzen 7 PRO 7840U improved by up to 18-23% compared to the baseline performance. This improvement is significant for users of older hardware who want to take advantage of the latest AI features.
Key points
- AMD's PerfOpt feature improves AI performance on older Ryzen APUs
- The feature is enabled by default in Linux 7.4 for Radeon integrated graphics
- Testing was done on an older Lenovo ThinkPad P14s Gen 4 with AMD Ryzen 7 PRO 7840U and Radeon 780M
- Performance improvements range from 18-23%
- The feature is significant for users of older hardware who want to take advantage of the latest AI features
With PerfOpt, older AMD Ryzen computers can now perform better with AI tasks, which can help people who are using these computers for work or other tasks.
However, not all older AMD Ryzen computers will see the same performance improvements, and some users might not notice a big difference.
