Measuring The Performance Cost To AMD Memory Guard With Ryzen AI PRO CPUs
Code compilation speed for large codebases and compiling with multiple jobs can also be impacted by the performance of AMD Memory Guard for RAM encryption by default on PRO processors.
So there can be a measurable performance cost to this full DRAM encryption via AMD Memory Guard on PRO processors, but for many workloads the cost isn't really significant and this feature is beneficial for added security.
👁 PHPBench benchmark with settings of PHP Benchmark Suite. DRAM Encryption Disabled was the fastest.
For many workloads you won't notice AMD Memory Guard is active by default on AMD Ryzen AI PRO / Ryzen AI Max PRO laptops.
