Apple Inc. is designing a new chip for future Mac laptops that would take more on the functionality that were previously handled by Intel Corp. processors, some sources close to the company revealed. Further it is said that the chip was sent for development last year, and is similar to the one used in latest Macbook Pro to power the keyboard's Touch Bar feature.

The updated part is internally codenamed as T310, is expected to handle some of the computer's low-power mode functionality. It is built using ARM Holdings Plc. technology and will simultaneously work alongside an Intel processor.

Apple have accounted for 7.5% of worldwide computer shipments in the fourth quarter, according to a data from IDC, but the Mac line has long set the standard for design and component developments. Its feature always start a new technological trend for other companies to follow, Apple and Intel refuse to comment on it currently.

The recent development of more advanced Apple-design chipset for use in Mac laptops is another step forward for the company towards becoming independent of Intel for its Mac processors. Apple has been using A-series processors inside iPhones and iPads since 2010. Its chip business now has become one of the most critical long-term investments.

Apple's first ARM-based Mac chip was named T1, introduced as part of Macbook Pro update last October. This chip basically powers Touch bar, a screen built into keyboard that lets users access app shortcuts, system settings and emojis. Along with it, there are some security features such as the enclave which stores payment and biometric data tied to to computer's fingerprint reader.

The current ARM-based chip is independent of computer's other components, focusing solely on Touch bar functionality. The new version is in development right now and will go further by connecting other parts of Mac system too, including storage and wireless components, with it takes the additional responsibilities.

Building its own chips will help Apple tie up its hardware and software functions nicely. Further more, it crucially allows more of a say in the cost of components for its devices. However, beyond these Apple have no intention to remove Intel chips in very near future.

Intel dipped on the news and ended the day down 0.8 percent at $36.52. Apple rose 6.1 percent to $128.75 in New York.
