Arm introduces new mobile device technology and chips for faster performance.

SoftBank-owned chip designer Arm has launched new technology for mobile devices, including the Immortalis-G720 chip for video image processing and AI applications, and the Cortex-X4 processor. Taiwan's MediaTek has said it will use the new chips in its next-generation smartphones. Arm said both new chips have 15% better performance than their previous generations, and the Cortex-X4 uses 40% less power. Arm also said it has "taped out" the Cortex-X4 at Taiwan Semiconductor Manufacturing Co, which means it had a chip manufactured at the factory.
