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.

Using WebXPRT 3 to compare the performance of popular browsers in Windows 10 and Windows 11

People choose a default web browser based on several factors. Speed is sometimes the deciding factor, but privacy settings, memory load, ecosystem integration, and web app capabilities can also come into play. Regardless of the motivations behind a person’s go-to browser choice, the dominance of software-as-a-service (SaaS) computing means that new updates are always right around the corner. In previous blog posts, we’ve talked about how browser speed can increase or decrease significantly after an update, only to swing back in the other direction shortly thereafter. OS-specific optimizations can also affect performance, such as with Microsoft Edge on Windows and Google Chrome on Chrome OS.

Windows 11 began rolling out earlier this month, and tech press outlets such as AnandTech and PCWorld have used WebXPRT 3 to evaluate the impact of the new OS—or specific settings in the OS—on browser performance. Our own in-house tests, which we discuss below, show a negligible impact on browser performance when updating our test system from Windows 10 to Windows 11. It’s important to note that depending on a system’s hardware setup, the impact might be more significant in certain scenarios. For more information about such scenarios, we encourage you to read the PCWorld article discussing the impact of the Windows 11 default virtualization-based security (VBS) settings on browser performance in some instances.

In our comparison tests, we used a Dell XPS 13 7930 with an Intel Core i3-10110U processor and 4 GB of RAM. For the Windows 10 tests, we used a clean Windows 10 Home image updated to version 20H2 (19042.1165). For the Windows 11 tests, we updated the system to Windows 11 Home version 21H2 (22000.282). On each OS version, we ran WebXPRT 3 three times on the latest versions of five browsers: Brave, Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera. For each browser, the score we post below is the median of the three test runs.

In our last round of tests on Windows 10, Firefox was the clear winner. Three of the Chromium-based browsers (Chrome, Edge, and Opera) produced very close scores, and the performance of Brave lagged by about 7 percent. In this round of Windows 10 testing, performance on every browser improved slightly, with Google Chrome taking a slight lead over Firefox.

In our Windows 11 testing, we were interested to find that without exception, browser scores were slightly lower than in Windows 10 testing. However, none of the decreases were statistically significant. Most users performing daily tasks are unlikely to notice that degree of difference.

Have you observed any significant differences in WebXPRT 3 scores after upgrading to Windows 11? If so, let us know!
