Casio’s newest PRO TREK smartwatch finally adds heart rate monitoring

Serious runners and outdoor athletes look to a handful of brands when they want the best wearable to connect them with the outdoors and track their ventures throughout. While Casio may have a place in such discussions, the lack of a heart rate monitor on its wearables seriously hindered that consideration for some. Finally, the newly announced PRO TREK WSD-F21HR changes this with Casio’s first hear rate-enabled smartwatch.

Focused on tracking and facilitating runs, cycles, and climbs via GPS and heart rate monitoring, this $500 Google WearOS-running wearable offers the durability, usability, and range of sensors needed to help you keep track of your exercise and the world around you.

The WSD-F21HR may not have a name that just rolls off the tongue, but it has a list of features that do. Packing an altimeter, barometer, compass, and GPS, the WSD-F21HR has all of the tracking ability of its predecessors, plus the newly added heart rate monitor. This takes real-time measurements to display which of the five heart rate zones you’re in and can be set to appear automatically on the home screen when it senses motion. Trekkers can also keep track of tides and fishing times, as well as sunrise and sunsets, and even follow along previously tracked routes via logged GPS information, all from the watches built-in software.

Casio’s Activity app has also been updated to include menus for running and trail running which show real-time stats for heart rate, pace, and distance. All logged data is saved to Google Drive, with the added ability to view activity history on Google Calendar.

The wearable does run Google’s WearOS, and is therefore compatible with any WearOS-compatible apps, like STRAVA, MapMyRun, and BIKEMAP. This smartwatch is compatible with iPhones, but will have much less third-party features.

The WSD-F21HR is water resistant up to 50 meters and meets the United States Military’s standard for environmental durability with regard to temperature, shock, and humidity.

Coming in black and red colorways, this latest smartwatch also features Casio’s signature dual-layer display which shows time, date, and other tidbits on a monochrome watchface, while underneath lies a 1.32-inch color display with resolution of 320 x 300.

Available for pre-order now, the WSD-F21HR is available through Amazon, Casio, and select retailers for $500 or 400 British pounds in the U.K.. Orders begin shipping September 13.

AMD is giving up on Windows 10
AMD's CEO delivering the Computex 2024 presentation.

It's official: AMD's Ryzen AI processors will not support Windows 10. With a neural processing unit (NPU) that reaches up to 50 trillion operations per second (TOPS), the Ryzen AI lineup is more than ready for the future -- so it makes sense that it'd also leave the past in the rearview mirror. As a result, today's findings are just a confirmation of previous rumors. But is this decision a big deal, and will it stretch toward other Zen 5 processors?

Microsoft's Copilot+ sparked a revolution that left AMD and Intel scrambling to release new CPUs that are capable of meeting the 40 TOPS requirement, so it's really no surprise that the laptops built around the AMD Ryzen AI 9 HX 370 and the Ryzen AI 9 365 will not support Windows 10. The chips were built for AI, and all of the latest developments in that area are in Windows 11. In fact, the Ryzen AI 300 series only supports Windows 11 64-bit and Ubuntu. This information comes straight from the source, as can be seen on the AMD product page.

Samsung’s upcoming and heavily leaked Galaxy Ring may be getting all the attention right now, especially with Samsung Galaxy Unpacked around the corner in July. However, it looks like Samsung may have an additional competitor soon. According to a report by Gadgets & Wearables, a patent was filed with the U.S. Patent and Trademark Office (USPTO), and it reveals that a new Fitbit smart ring is in the pipeline.

It’s official: AMD Ryzen AI 300 is up to 40% faster
AMD announcing its Ryzen AI CPUs at Computex 2024.

AMD's upcoming Ryzen AI APUs stole the show at Computex 2024, but we haven't seen them in action -- until now. Three Geekbench tests have just leaked, showcasing the performance of AMD's flagship APU, and it's safe to say that it did an excellent job. It's not just the highest number of TOPS in an NPU that AMD can now brag about -- it's also competitive, desktop-worthy CPU performance and a vastly improved GPU. Let's dig in.

The Ryzen AI 9 HX 370 appeared in two Geekbench tests and one OpenCL test, meaning that we get some insight into both CPU and GPU performance. Before we get into comparing test scores, it's worth noting that in these tests, the APU appears under the name of AMD Ryzen AI 9 HX 170 with a Radeon 880M GPU. In reality, as Wccftech points out, AMD appears to have changed its naming scheme at the last minute, and the HX 170 is now the HX 370. The GPU in that model should also be the 890M, so there are some discrepancies.
