Last Update

2021-03-14

This article reports performace measurement result related to AVX2-enabled plugins.

Test Environment

• Intel Core i7-6700K
• DDR4-2166 16GB main memory
• RME HDSPe AES
• Samplitude Pro X5
• Buffer Size: 256 samples
• A.O.M. Audio Plug-ins v1.11.4

Measurement

CPU Load[%] = Processing Time[second] ÷ (Buffer Size[samples] ÷ Sampling Frequnecy[Hz]) × 100

• Used time profiler-enabled private build. Other settings (like optimization) are same to release build.
• std::chrono is used for time measurement.
