Local AI and new frontiers for performance evaluation

Recently, we discussed some ways the PC market may evolve in 2024, and how new Windows on Arm PCs could present the XPRTs with many opportunities for benchmarking. In addition to a potential market shakeup from Arm-based PCs in the coming years, there’s a much broader emerging trend that could eventually revolutionize almost everything about the way we interact with our personal devices—the development of local, dedicated AI processing units for consumer-oriented tech.

AI already impacts daily life for many consumers through technologies such as such as predictive text, computer vision, adaptive workflow apps, voice recognition, smart assistants, and much more. Generative AI-based technologies are rapidly establishing a permanent, society-altering presence across a wide range of industries. Aside from some localized inference tasks that the CPU and/or GPU typically handle, the bulk of the heavy compute power that fuels those technologies has been in the cloud or in on-prem servers. Now, several major chipmakers are working to roll out their own versions of AI-optimized neural processing units (NPUs) that will enable local devices to take on a larger share of the AI load.

Examples of dedicated AI hardware in recently-released or upcoming consumer devices include Intel’s new Meteor Lake NPU, Apple’s Neural Engine for M-series SoCs, Qualcomm’s Hexagon NPU, and AMD’s XDNA 2 architecture. The potential benefits of localized, NPU-facilitated AI are straightforward. On-device AI could reduce power consumption and extend battery life by offloading those tasks from the CPUs. It could alleviate certain cloud-related privacy and security concerns. Without the delays inherent in cloud queries, localized AI could execute inference tasks that operate much closer to real time. NPU-powered devices could fine-tune applications around your habits and preferences, even while offline. You could pull and utilize relevant data from cloud-based datasets without pushing private data in return. Theoretically, your device could know a great deal about you and enhance many areas of your daily life without passing all that data to another party.

Will localized AI play out that way? Some tech companies envision a role for on-device AI that enhances the abilities of existing cloud-based subscription services without decoupling personal data. We’ll likely see a wide variety of capabilities and services on offer, with application-specific and SaaS-determined privacy options.

Regardless of the way on-device AI technology evolves in the coming years, it presents an exciting new frontier for benchmarking. All NPUs will not be created equal, and that’s something buyers will need to understand. Some vendors will optimize their hardware more for computer vision, or large language models, or AI-based graphics rendering, and so on. It won’t be enough for business and consumers to simply know that a new system has dedicated AI processing abilities. They’ll need to know if that system performs well while handling the types of AI-related tasks that they do every day.

Here at the XPRTs, we specialize in creating benchmarks that feature real-world scenarios that mirror the types of tasks that people do in their daily lives. That approach means that when people use XPRT scores to compare device performance, they’re using a metric that can help them make a buying decision that will benefit them every day. We look forward to exploring ways that we can bring XPRT benchmarking expertise to the world of on-device AI.

CES 2023: Adapting to changing realities

The last time the XPRTs attended the Consumer Electronics Show in Las Vegas was in January 2020, shortly before shutdowns due to the global pandemic began. More than 171,000 people attended that year’s show, the 2021 show was totally virtual, and CES shortened the 2022 show after many exhibitors and media pulled out during the Omicron surge. While some aspects of the event are returning to normal this year, about one-third of the typically jam-packed Las Vegas Convention Center space is empty, and only about 100,000 people are likely to attend. Nevertheless, the show is still enormous and full of fascinating new technology.

Just one day into the show, I’ve already noticed some interesting changes in the virtual reality (VR) and augmented reality (AR) areas since I last attended in 2020. One change is a significant expansion in the sensory capabilities of VR equipment. For a long time, VR technologies have focused almost solely on visual and audio input technology and the graphics-rendering capabilities necessary for lag-free, immersive experiences. In 2020, I saw companies working on various types of haptic feedback gear, including full-body suits, that pushed the boundaries of VR beyond sight and sound. Now, several companies are demonstrating significant progress in “real-feel touch” technologies for VR. One such company is HaptX, which is developing a set of gloves (see the picture below) that pump air through “microfluidic actuators” so that users can feel the size and shape of virtual objects they interact with in a VR environment. While we often think of VR being used for gaming and entertainment, advances in realistic, multi-sensory capabilities can lead to VR becoming a valuable tool for all kinds of industrial and professional training applications.

Another change I’ve noticed is how AR seems poised to move from demos to everyday life by means of integration with all types of smartphone apps. I enjoyed speaking with a representative from a Korean AR company called Arbeon. Arbeon is developing an app that will allow users to point their phone’s camera at an object (a wine bottle in the picture below), and see an array of customizable, interactive AR animations surrounding the object. You’ll be able to find product info, see and leave feedback similar to “likes” and reviews, attach emojis, tag friends, and even purchase the product, all from your phone’s AR-enhanced camera and screen. It’s an interesting concept with limitless applications. While VR is here to stay and getting better all the time, I personally think that AR will become much more integrated into everyday life in the coming years. I also think AR apps for phones will allow the technology to take off more quickly in the near term than clunkier options like AR eyeglasses.

The large screen displays how Arbeon’s AR phone app interacts with objects like a wine bottle.

Of course, thinking about AR has led me to wonder if we’ll be able to incorporate AR-related workloads into future XPRTs. As new technologies place new and unprecedented levels of processing demand on our computing hardware, the need for objective performance evaluation will continue. Providing reliable, objective performance data is why the XPRTs exist, and planning for the future of the XPRTs is why we’re at CES 2023. If you have any thoughts about how the XPRTs can help to evaluate new technologies, we’d love to hear from you!

A new HDXPRT 4 build is available!

A few weeks ago, we announced that a new HDXPRT 4 build, v1.1, was on the way. This past Monday, we published the build on HDXPRT.com.

The new build includes an updated version of HandBrake, the commercial application that HDXPRT uses for certain video conversion tasks. HandBrake 1.2.2 supports hardware acceleration with AMD Video Coding Engine (VCE), Intel Quick Sync, and the NVIDIA video encoder (NVENC). By default, HDXPRT4 v1.1 uses the encoder available through a system’s integrated graphics, but testers can target discrete graphics by changing a configuration file flag before running the benchmark. HDXPRT will then use the encoder provided by the discrete graphics hardware. This configuration setting takes effect only when more than one of the supported encoders (VCE, QSV, or NVENC) is present on the system.

As we mentioned before, in all other respects, the benchmark has not changed. That means that, apart from a scenario where a tester changes the targeted graphics hardware, scores from previous HDXPRT 4 builds will be comparable to those from the new build.

The updated HDXPRT 4 User Manual contains additional information and instructions for changing the configuration file flag. Please contact us if you have any questions about the new build. Happy testing!
