Google appears to be readying an upgrade to its hardware security with the next generation of its custom Tensor silicon. Since the release of Titan M on Pixel 3 and its RISC-V-based Titan M2 chipset follow-up, Google is seemingly working on Titan M3 to beef up Pixel's hardware-level security.
Titan M3 could debut with Tensor G6
According to a report from Mystic Leaks on Telegram, Google is developing a new Titan M3 security coprocessor that could launch alongside the upcoming Tensor G6 (codenamed Malibu).
The new M3 chipset is internally codenamed Google Epic. It is running firmware called "longjing" If accurate, this would mark the first major refresh to Google's dedicated security silicon since the release of Titan M2 on Pixel 6.
Mystic Leaks also suggests that Titan M3 is designed to bring significant architectural improvements to compete more directly with the latest iterations of Apple's Secure Enclave Processor used in the iPhones, which runs Apple's customised version of the L4 microkernel.
While specific details about the Titan M3 and the Tensor G6 remain scarce, we do know that Titan M3 will be a RISC-V-based chipset. The Titan M2 was marketed for its ability to fend off advanced attacks like laser fault injection. It also handles bootloader validation and the storage of private encryption keys via StrongBox KeyStore.
Another user-facing scenario that the Titan co-processor helps with, indirectly, is Factory Reset Protection on Pixels. For example, if a thief tries to load a tampered OS to bypass FRP, the Titan M2 halts the boot sequence.
More information about the Tensor G6 and the Titan M3 processor should be unveiled as we inch closer to the launch of the Pixel 11 series. It should happen sometime in August 2026 this year, so stay tuned.
