👁 OpenVKL benchmark with settings of Benchmark: vklBenchmarkGPU Intel oneAPI SYCL. Core Ultra X7 358H Panther Lake was the fastest.

For the Open Volume Kernel Library there was little benefit over Lunar Lake for this particular benchmark.

👁 OSPRay Studio benchmark with settings of Camera: 1, Resolution: 1080p, Samples Per Pixel: 1, Renderer: Path Tracer, Acceleration: oneAPI SYCL GPU. Core Ultra X7 358H Panther Lake was the fastest.

👁 OSPRay Studio benchmark with settings of Camera: 1, Resolution: 1080p, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: oneAPI SYCL GPU. Core Ultra X7 358H Panther Lake was the fastest.

👁 OSPRay Studio benchmark with settings of Camera: 2, Resolution: 1080p, Samples Per Pixel: 1, Renderer: Path Tracer, Acceleration: oneAPI SYCL GPU. Core Ultra X7 358H Panther Lake was the fastest.

👁 OSPRay Studio benchmark with settings of Camera: 2, Resolution: 1080p, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: oneAPI SYCL GPU. Core Ultra X7 358H Panther Lake was the fastest.

Intel's OSPRay Studio software with GPU-based rendering was painfully slow on Meteor Lake while a night-and-day difference with Lunar Lake's Xe2 graphics Now with Xe3 graphics on Panther Lake are very nice gains compared to Lunar Lake both for performance and power efficiency.

👁 OSPRay Studio benchmark with settings of Camera: 3, Resolution: 1080p, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: oneAPI SYCL GPU. Core Ultra X7 358H Panther Lake was the fastest.

Very nice performance and power efficiency improvements for OSPRay Studio use from Lunar Lake to Panther Lake.

👁 CPU Power Consumption Monitoring Overview benchmark with settings of Accumulated CPU Power Consumption Monitoring.

👁 Geometric Mean Of All Test Results benchmark with settings of Result Composite, Intel SYCL oneAPI iGPU Benchmarks Panther Lake. Core Ultra X7 358H Panther Lake was the fastest.

Across these iGPU benchmarks with OpenVINO and Intel Rendering Toolkit packages, going from Lunar Lake to Panther Lake was 1.2x the performance. That 1.2x performance was delivered with just 1.13x the power use of the Core Ultra 7 258V. Driven in large part by the very slow OSPRay Studio performance on Meteor Lake, going from the Core Ultra 7 155H to the Core Ultra X7 355H was 2.9x the performance with these GPU compute benchmarks.
