Fabless Taiwanese chip biz MediaTek has unveiled the fourth flagship entry in its Dimensity family of system-on-chips for smartphones and other mobile devices. It's sticking with close companion Arm rather than jumping ship to RISC-V for the CPU cores, for those wondering. The Dimensity 9400 processor – a rival to Qualcomm's …

So you'll be charging your phone every day, as usual.

Genuinely challenging Qualcom

The 9400 is being touted as a genuine competitor, performance-wise, for the Snapdraggon 8 gen 4 (or whatever it will be called)

^{(ARM added the Kleidi library to PyTorch and ExecuTorch to accelerate AI right on the shake-and-bake CPU itself last month)}
