And very strong uplift out of TensorFlow with AVX-512... Beyond the performance provided by 16 cores in a laptop form factor and the Radeon 8060S graphics being available too for accelerating AI workloads with Vulkan or ROCm.

👁 OpenVINO benchmark with settings of Model: Face Detection FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Age Gender Recognition Retail 0013 FP16-INT8, Device: CPU. AVX-512 On was the fastest.

Intel's own OpenVINO open-source AI toolkit continues showing the great capabilities of AVX-512 on Strix Halo.

👁 OpenVINO benchmark with settings of Model: Person Detection FP16, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Weld Porosity Detection FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Vehicle Detection FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Person Vehicle Bike Detection FP16, Device: CPU. AVX-512 On was the fastest.

OpenVINO is well tuned for AVX-512 to benefit Intel Xeon processors but it also performs pretty darn well on AMD Zen 4 and Zen 5 processors too from laptops to servers.

👁 OpenVINO benchmark with settings of Model: Face Detection Retail FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Handwritten English Recognition FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Road Segmentation ADAS FP16-INT8, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Person Re-Identification Retail FP16, Device: CPU. AVX-512 On was the fastest.

👁 OpenVINO benchmark with settings of Model: Noise Suppression Poconet-Like FP16, Device: CPU. AVX-512 On was the fastest.

AVX-512 helps a lot for these AI workloads on the CPU cores of Strix Halo while not hurting the power/thermal characteristics of the HP ZBook Ultra G1a.
