- The Arm’s design may be partly to blame for Samsung and Qualcomm’s overheating problems.
- There may be a solution, but it will not be easy to achieve.
Samsung has been in the news for throttling its phones, but the underlying problem is far more widespread and is likely to get worse.
Samsung admitted to throttling the apps, though it said the reason was to keep the phone from overheating. There may be more to Samsung’s claim than some originally thought, and it may not be entirely the company’s fault. As per reports, the flaw could lie with the underlying Arm design on which flagship processors from Samsung and Qualcomm are based.
Unlike Intel, Arm does not manufacture its own chips. Instead the firm designs the processors and licenses those designs to any interested company. Qualcomm and Samsung are two of Arm’s biggest clients, with both companies using Arm’s design in their respective Snapdragon and Exynos flagship processors.
Interestingly, Apple’s chips seem to be unaffected, despite being based on the Arm design. Industry experts believe that Apple and Arm have been able to better tune the processor for use with iOS. In contrast, Samsung and Qualcomm are saddled with the task of making their chips work with different device manufacturers and versions of Android, making it very difficult for those processors to be as optimized as Apple’s A-series or M1s.
“The iPhones are also based on Arm’s chip design but Apple and Arm tune the processor for use in iOS,” said business of korea Industry sources, adding, “Samsung Electronics and Qualcomm, on the other hand, are developing application processors for use in various models from several manufacturers and it appears that processors using the unmodified design are causing problems. “
Hopefully, Qualcomm and Samsung will figure out an efficient way to tune their designs to compete with Apple’s energy efficiency. Otherwise, overheating phones and throttled processors may become the new norm.
