Hitting these desktop processors first was Llama.cpp for some CPU-based AI inferencing. Interestingly for Llama.cpp the Framework Desktop with Ryzen AI Max+ 395 delivered a narrow lead over the Ryzen 9 9950X and 9950X3D processors. Part of the Ryzen AI Max+ 395 advantage here may be due to its LPDDR5-8000 memory feeding the Zen 5 cores. What was really astonishing was the CPU performance-per-Watt lead of Strix Halo.

The Llama.cpp-powered LocalScore AI benchmark from Mozilla was also showing the Ryzen AI Max+ 395 performance comparable to the 9950X/9950X3D but with far greater power efficiency.

👁 ONNX Runtime benchmark with settings of Model: yolov4, Device: CPU, Executor: Standard. Ryzen 9 9950X3D was the fastest.

👁 ONNX Runtime benchmark with settings of Model: super-resolution-10, Device: CPU, Executor: Standard. Ryzen 9 9950X3D was the fastest.

👁 ONNX Runtime benchmark with settings of Model: GPT-2, Device: CPU, Executor: Standard. Ryzen 9 9950X3D was the fastest.

👁 ONNX Runtime benchmark with settings of Model: ArcFace ResNet-100, Device: CPU, Executor: Standard. Ryzen 9 9950X3D was the fastest.

Meanwhile for Microsoft's ONNX Runtime the raw performance was trailing the Ryzen 9 9950X series desktop processors but with superior power efficiency.
