ARM debuts eight-core mobile graphics processor

British processor ARM Mali-T658 Chip Diagramdesigner ARM has taken the wraps off its new Mali-T658 graphics processor, which packs eight graphics processing cores where the company currently offers only four—and each of those eight cores runs twice as fast as its predecessors. According to ARM, the Mali-T658 will be an important step in delivering PS3-quality graphics on smartphones and tablets—and it could start appearing in mobile devices by 2013. The chip will likely also get consideration from makers of smart TVs and in-vehicle information and entertainment systems.

“Next generation consumer devices based on the Mali-T658 GPU will address the growing user expectation for slick user interfaces and desktop-class graphics,” said the general manager of ARM’s Media Processing Division Pete Hutton, in a statement. “Intuitive user interfaces will mean that consumers can access the full functionality of their connected devices, for richer user experiences. This includes HD gaming and new compute-intensive applications, such as augmented reality.”

The Mali-T658 is designed to worth seamlessly with ARM’s Cortex A7 and A15 processors, either as a standalone system or in ARM’s big.LITTLE mode, which essentially combines ARM’s Cortex A15 and A7 processors, enabling hardware to jump up to more serious (and more power-consumptive) processing when needed, while scaling back to power-sipping processing during less demanding tasks. The availability of GPU units to take on discrete processing tasks could also help with non-graphical mobile applications, including speech recognition and augmented reality apps.

The 2013 date for the Mali-T658 graphics processor reflects the length of ARM’s technology roadmap: the T658 is actually the follow-on to the Mali-T604, which has four graphics processing cores. The T604 itself hasn’t shipped in any products yet: it should start appearing in smartphones and tablets during 2012.

Although a wide variety of portable devices use processors based on ARM designs, not all use ARM’s graphics technology: Samsung’s Galaxy line is perhaps the best-known user of ARM graphics, and Fujitsu and LG have also signed on to use the Mali-T658 when it’s available. However, Nvidia and Qualcomm also makes graphics processing systems for ARM-based systems (Nvidia and Adreno, respectively), and the UK’s Imagination Technologies designed the graphic processors used by Apple’s iPad and iPhone products.

The Apple Car may be dead, but it became the foundation of Apple Intelligence
A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.
Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Researchers hid a prompt injection inside a PNG, and AI fell for it

AI coding assistants like Claude are becoming every developer's favorite coworker. They can review code, explain confusing functions, and even write entire features with a single prompt. But new research suggests that this growing trust could also become their biggest weakness.

A team of security researchers (professor Sudipta Chattopadhyay and researcher Murali Ediga) has demonstrated an unusual attack that doesn't target the AI model directly. Instead, it targets what the AI doesn't pay enough attention to during code reviews. Rather than hiding malicious instructions in lines of code, the researchers tucked them inside an image file. Since many AI review tools treat images as decorative assets rather than as something worth inspecting, the pull request can appear perfectly harmless and sail through the review.

AI has already fallen into the wrong hands and they’re using it to make bombs

Artificial intelligence has quickly become the go-to tool for everything from writing emails and summarizing meetings to helping students study or developers debug code. But the same technology that saves people time can also be misused, and a new report suggests that terrorist organizations are finding ways to do exactly that.

According to a research paper shared with The New York Times ahead of its publication, researchers found evidence that members of Boko Haram have been using popular AI chatbots to support both day-to-day activities and combat-related tasks. Interviews with 27 former members conducted in Nigeria over the past two years suggest that tools such as ChatGPT, Gemini, Claude, Grok, Meta AI, and DeepSeek were used to gather technical information, troubleshoot weapons, and even assist with planning attacks.
