Application: Embree 2.2 Pathtracer Renderer using Embree and<br />
Optix* RT Libraries<br />
Description: Pathtracing app for use in benchmarking RT libraries<br />
Availability:<br />
• Code: Available here<br />
• Recipe: embree.github.io; http://embree.github.com<br />
Usage Model:<br />
• Native on Intel® Xeon® processor, COI-based offload on Intel®<br />
Xeon Phi coprocessor. Intel® TBB, ISPC and Intrinsics<br />
Highlights:<br />
• Typical ray tracing rendering pipeline code used throughout DCC<br />
to show comparative performance on different types of hardware<br />
with a variety of input 3D data models. Optimized for all Intel ISAs<br />
and delivered to the community and available for download.<br />
• End-User benefits: Ability to achieve competitive performance and<br />
the flexibility of IA for rendering and render farm applications<br />
Results:<br />
• Embree on Intel® Xeon Phi 7120A coprocessor performs up to<br />
2.15X faster than Nvidia<br />
– Path tracing causes low SIMD utilization (better for Xeon)<br />
– Xeon® E5-2699 v3 is latest silicon while Xeon Phi 7120A now<br />
2.5 years old<br />

Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems,<br />
components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated<br />
purchases, including the performance of that product when combined with other products. For more information go to http://www.intel.com/performance *Other names and brands may be claimed as the property of others<br />
