Intel NUC 13 Pro Arena Canyon Review: Raptor Lake Brings Incremental Gains

HTPC and Digital Signage Credentials

The 2022 Q4 update to our system reviews brings an updated media playback evaluation suite for systems. After doing away with the evaluation of display refresh rate stability and Netflix streaming evaluation, the local media playback configurations have also seen a revamp. This section details each of the workloads processed on the Intel NUC13ANKi7 (Arena Canyon).

YouTube Streaming Efficiency

YouTube continues to remain one of the top OTT platforms, primarily due to its free ad-supported tier. Our HTPC test suite update retains YouTube streaming efficiency evaluation as a metric of OTT support in different systems. Mystery Box's Peru 8K HDR 60FPS video is the chosen test sample. On PCs running Windows, it is recommended that HDR streaming videos be viewed using the Microsoft Edge browser after putting the desktop in HDR mode.

YouTube Streaming Statistics

The GPU in Intel NUC13ANKi7 (Arena Canyon) supports hardware decoding of VP9 Profile 2, and we see the stream encoded with that codec being played back. The streaming is perfect, thanks to the powerful GPU and hardware decoding support - the dropped frames observed in the statistics below are due to mouse clicks involved in bringing up the overlay.

The streaming efficiency-related aspects such as GPU usage and at-wall power consumption are also graphed below.

Energy consumption is a bit of a mixed bag, with the Arena Canyon NUC turning out to be the worst of the lot. It is possible that the iGPU drivers are to blame, but we do not see the issue in other playback workloads.

Hardware-Accelerated Encoding and Decoding

The transcoding benchmarks in the systems performance section presented results from evaluating the QuickSync encoder within Handbrake's framework. The capabilities of the decoder engine are brought out by DXVAChecker.

Video Decoding Hardware Acceleration in Intel NUC13ANKi7 (Arena Canyon)

The iGPU in Raptor Lake-P system supports hardware decode for a variety of codecs including AVC, JPEG, HEVC (8b and 10b, 4:2:0 and 4:4:4), and VP9 (8b and 10b, 4:2:0 and 4:4:4). AV1 decode support is also present. This is currently the most comprehensive codec support seen in the PC space.

Local Media Playback

Evaluation of local media playback and video processing is done by playing back files encompassing a range of relevant codecs, containers, resolutions, and frame rates. A note of the efficiency is also made by tracking GPU usage and power consumption of the system at the wall. Users have their own preference for the playback software / decoder / renderer, and our aim is to have numbers representative of commonly encountered scenarios. Our Q4 2022 test suite update replaces MPC-HC (in LAV filters / madVR modes) with mpv. In addition to being cross-platform and open-source, the player allows easy control via the command-line to enable different shader-based post-processing algorithms. From a benchmarking perspective, the more attractive aspect is the real-time reporting of dropped frames in an easily parseable manner. The players / configurations considered in this subsection include:

• VLC 3.0.18
• Kodi 20.0b1
• mpv 0.35 (hwdec auto, vo=gpu-next)
• mpv 0.35 (hwdec auto, vo=gpu-next, profile=gpu-hq)

Fourteen test streams (each of 90s duration) were played back from the local disk with an interval of 30 seconds in-between. Various metrics including GPU usage, at-wall power consumption, and total energy consumption were recorded during the course of this playback.

All our playback tests were done with the desktop HDR setting turned on. It is possible for certain system configurations to automatically turn on/off the HDR capabilities prior to the playback of a HDR video, but, we didn't take advantage of that in our testing.

Playback was perfect for all codecs except AV1 (the CPU is not strong enough for software-only 8Kp60 decoding). Power consumption numbers are reasonable, and help the Arena Canyon NUC land up in the middle of the pack.

The scenario seen with VLC is replicated in Kodi also. The middle-of-the-pack entry seen in the VLC case makes an appearance here also, with the software decoding attempt for AV1 being one of the main causes for the spike in the energy numbers.

mpv playback with the gpu-next video output driver is the most energy efficient of the lot. We also have hardware accelerated decode for AV1. However, the playback for that clip still has issues, with approximately 60% of the frames getting dropped in the video output (the decoder itself doesn't drop any frames).

Activating the GPU shaders for video post processing does result in increased energy consumption, but there are no dropped frames. The 8Kp60 AV1 decode video output issue remains the same irrespective of the profile used.
