ARM, the company’s which designs chips that power the majority of Android devices out there, today unveiled its latest flagship mobile processor design: Cortex-A75. The company says that its new flagship chip design boasts of a 22 percent improvement in performance over its predecessor, the Cortex-A73.
In addition, ARM also unveiled its new mid-range Cortex-A55 chip design which has the highest power efficiency of any chip ever unveiled by the company.
The two new chip designs will be available under the company’s DynamIQ CPUs brand which means that OEMs are free to pair any number of cores in any order they wish to. This means, that while we have so far seen octa-core and hexa-core big.LITTLE implementations, we can now see 1x Cortex-A75 CPU being paired with 7x Cortex-A55 cores DynamIQ configurations ensuring the best in terms of power efficiency and single-threaded performance.
With Cortex-A55, ARM has focused on improving performance by integrating an L2 cache that reduces latency by 50 percent and a new data prefetcher that leads to a substantial performance improvement while still being up to 15 percent more power efficient than Cortex-A53 despite the slightly higher power consumption.
Then, there’s the Cortex-A75 which ARM claims offers 22 percent better performance than the A73. The chip design now also supports a bigger power envelope as ARM wants to push this chip for use in bigger mobile devices, Chromebooks, and 2-in-1s.
