Primate Labs today announced the launch of Geekbench 7, the newest version of the popular benchmarking suite for CPU and GPU performance.


There's a redesigned multi-core benchmark in Geekbench 7 that's meant to better represent how applications work in the real world. A workload only runs in multi-threaded mode if the task it models runs multi-threaded in real applications.

Primate Labs says users can expect a multi-core score that's a more relevant measure of how a device performs when doing actual work.

Along with updates to multi-core testing, a revamped GPU benchmark focuses on machine learning and content creation to reflect how GPUs are used today. The GPU benchmark has tests that track faces and apply real-time filter effects to video, upscale images with machine learning, and blur backgrounds in video conferencing streams. New GPU image editing and synthesis tests are available, like RAW image processing, LUT-based video color grading, path tracing, and fluid simulation.

Nvidia's CUDA is once again a supported API alongside OpenCL, Vulkan, and Metal.

The new version of Geekbench uses more challenging data sets to better reflect how people use their computers today. The File Compression and PDF Viewer workloads have more variation, and developer and image processing tests have more assets and different image formats.

Geekbench 7 adds media workloads for testing audio and video encoding, decoding, and processing. The Whisper speech recognition, AV1, and Opus tests mimic video conferencing, screen sharing, and content consumption workloads.

There's also a Game Physics workload that uses the Jolt Physics engine used by popular video games. Primate Labs added an expanded Photo Editor test with a richer set of real-world edits, and the Photo Library workload supports importing and processing image formats like JPEG XL and DNG.

Geekbench 7 is available for iOS, macOS, and other platforms. The app remains free for personal use, and the Pro version is 20 percent off the regular $99 price through August 6.

It can be unsettling what Gemini and ChatGPT have figured out about you and how easily your privacy can be punctured. Here’s how to find out.

A new study in Nature Communications reports that subducting slabs can become effectively “stalled” for long periods—not simply due to mantle temperature or plate motion, but because distinct rock assemblages within the downgoing plate alter how the slab interacts with the surrounding mantle. Using geophysical constraints combined with thermodynamic modeling, the researchers argue that slab dynamics depend on whether the slab interior is dominated by hydrated ultramafic lithologies or by comparatively dry basaltic components.

The central finding is that wet harzburgite—an olivine-rich, ultramafic rock—can sustain slab stagnation by promoting hydration-related weakening processes and controlling the timing and location of mineral transformation. In parallel, the team shows that dry basaltic slab assemblages can also contribute to stagnation, but through a different pathway: by limiting certain water-driven reactions while still maintaining a mechanically coherent, slow-moving interface at depth.

According to the authors, the fate of volatiles is the key variable. As the slab descends, pressure and temperature drive phase changes and dehydration reactions. These reactions can either increase or decrease the effective viscosity and friction along plate boundaries, shifting the balance between slab pull and mantle resistance. Where hydration is sustained, water remains available to weaken lithospheric portions that would otherwise become too rigid to decouple.

In the wet harzburgite scenario, dehydration and metamorphic reactions are predicted to sustain zones of reduced strength within the slab, preventing it from sinking efficiently into the lower mantle. This creates a feedback loop: slower descent limits thermal loss, which in turn preserves conditions that keep the weakening processes active.

In the dry basaltic scenario, the model emphasizes that even without abundant water, basaltic mineralogy can maintain mechanical coupling over a broader depth range. The study suggests that dry assemblages may delay the development of decoupling horizons, thereby prolonging stagnation until the slab eventually transitions to a different rheological regime.

The researchers also connect their results to the observed diversity of subduction-zone behavior, where some slabs advance smoothly while others appear to linger at mantle depths. By treating rock composition explicitly rather than assuming uniform slab properties, the work offers a framework for interpreting why similar plate boundary geometries can yield markedly different slab lifetimes.

Crucially, the analysis links mineral stability, dehydration partitioning, and viscosity contrasts into a single physical narrative. This moves slab “stalling” away from a purely geometric explanation and toward a lithology-driven process that can be tested against seismic signatures.

The findings will likely influence how future models incorporate water budgets and rock types in subduction simulations. If validated by geophysical observations, the wet-versus-dry assemblage distinction could become a practical lever for predicting which slabs will stagnate and for how long.

In short, the study portrays slab stagnation as a sustained state maintained by the contrasting rheological effects of hydrated harzburgite and comparatively dry basaltic materials, reshaping our understanding of how deep Earth water and rock chemistry govern plate evolution.

The First Nuclear-Powered Satellite is Now in Orbit

Tuesday marked a new chapter in the quest for novel power systems for spacecraft, with the launch of the world’s first satellite equipped with a commercial betavoltaic nuclear power system.

The City Labs Betavoltaic Orbital High-Reliability (BOHR) satellite was carried to space on board a SpaceX Falcon 9 rocket, and in the coming weeks will begin tests to determine whether miniature nuclear batteries can reliably generate electricity in space.

Designed primarily as a proof of concept, the first BOHR satellite will rely on conventional solar panels for its primary power system. However, the first-of-its-kind spacecraft also carries the company’s proprietary “NanoTritium” betavoltaic power source, which, according to the company, uses beta particles emitted during the radioactive decay of tritium that are converted into electricity.

In a statement, Peter Cabauy, CEO of City Labs, called this week’s launch “a historic step for commercial nuclear power in space,” adding that the BOHER satellite “demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment.”

“This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life,” Cabauy added.

Harnessing the Power of Beta Radiation

The innovative satellite was carried to space earlier this week as part of the recent SpaceX Transporter-17 mission.

“On Tuesday, July 7 at 12:12 a.m. PT, Falcon 9 launched the Transporter-17 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California,” read an update that appeared at the SpaceX website announcing the successful launch that carried the City Labs BOHR satellite to space.

“Transporter-17 was a dedicated smallsat rideshare mission,” SpaceX’s update earlier this week added. “There were 81 payloads on this flight, including cubesats, microsats, hosted payloads, and orbital transfer vehicles carrying eight of those payloads to be deployed at a later time.”

Following the satellite’s successful delivery to orbit, its power systems will begin testing the feasibility of beta radiation as a primary driver to produce electricity. In the past, radioisotope thermoelectric generators have been used to propel landmark space missions, such as Voyager 1 and Voyager 2. By contrast, BOHR’s beta radiation system does not rely on heat generated by radioactive decay, which allows for a compact power source that, if all goes according to plan, could one day be deployed in future missions to support spacecraft operating in environments where sunlight is limited. Such applications include the permanently shadowed craters on the Moon and future missions into the outer solar system.

Primarily, City Labs says a tritium-based system is also more beneficial than traditional nuclear fuels like plutonium since it emits relatively low-energy radiation. This, the company says, makes it easier to shield and safer to handle during spacecraft assembly and launch.

Challenges Ahead

The technology does face significant hurdles, however. One involves the fact that tritium is presently still one of the world’s rarest—and most expensive—radioactive materials. Right now, with only around 20 kilograms produced annually throughout the world, the limited quantity and exorbitant costs (current prices reach tens of thousands of dollars per gram) make large-scale adoption anytime in the near term a significant challenge.

There are also regulatory considerations, as noted in a news article released this week by the American Nuclear Society (ANS) following the launch. “In 2019, National Security Presidential Memorandum – 20 (NSPM-20) laid out updates to the process for launching spacecraft containing nuclear systems,” the article states.

“Now the Department of Transportation, which includes the Federal Aviation Administration (FAA), directs the coordination of various agencies to review the safety analysis for missions with nuclear components,” the ANS news brief added, noting that the FAA updated its launch regulations in 2020.

Despite the existence of a few hurdles and other considerations, the mission nonetheless marks an important milestone in the development of next-generation spacecraft power systems. If successful, BOHR could demonstrate that compact betavoltaic power sources are a viable complement to solar energy, opening new possibilities for long-duration missions in some of the darkest and most remote regions of the solar system.
