👁 OpenVINO GenAI benchmark with settings of Model: TinyLlama-1.1B-Chat-v1.0, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: granite-3.0-8b-instruct, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: Qwen2.5-1.5B-Instruct, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: Qwen2.5-Coder-0.5B-Instruct, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: Qwen2.5-VL-3B-Instruct, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: Qwen3-8B, Device: GPU. Core Ultra 7 258V Lunar Lake was the fastest.

With OpenVINO GenAI there did appear to be a driver/software bug or other anomaly with the Panther Lake graphics falling short of Lunar Lake with the different models tested. Hopefully this software deficiency for the Arc B390 Graphics with OpenVINO GenAI can be addressed soon considering the good Panther Lake showing in the other OpenVINO benchmarks.

👁 Intel Open Image Denoise benchmark with settings of Run: RT.hdr_alb_nrm.3840x2160, Device: Intel oneAPI SYCL. Core Ultra X7 358H Panther Lake was the fastest.

👁 Intel Open Image Denoise benchmark with settings of Run: RTLightmap.hdr.4096x4096, Device: Intel oneAPI SYCL. Core Ultra X7 358H Panther Lake was the fastest.

With the Open Image Denoise library that is used by Blender and other creator software, there was very nice generational gains each step of the way on the Intel graphics. The performance-per-Watt also showed a nice improvement with Panther Lake.
