Most devices these days use chipsets featuring CPU and GPU cores from ARM, with new hardware announced once a year. Well, that time of the year has come and the company has now announced the Cortex-A78 and Cortex-X1 CPU cores, as well as Mali-G78 GPU that will greatly boost the performance of future smartphones.
In a series of official posts, ARM introduced a few new technologies that improve on current ones by a significant margin. First, there's the Cortex-A78 that can provide up to 20% more sustained performance compared to the Cortex-A77. What's impressive is that the CPU core takes up less space and reduces energy consumption by up to 50%.
Then there's the Cortex-X1, a custom line of CPU cores that can get up to 30% more peak performance than the Cortex-A77. ARM stated that the Cortex-X1 will be meant for smartphones with new form factors, with the examples of devices with foldable or multiple screens. The blog post about it doesn't explain the reasons behind the idea, but it's possible that the Cortex-X1 being customisable means it'll better fit these new form factors.
Finally, ARM also introduced the new Mali-G78 GPU. Compared to its predecessor, the Mali-G77, the new GPU's performance is up to 25% better. The feature called Asynchronous Top Level is what's helping the GPU cores work more efficiently and reduce power consumption. Additionally, there's a lower-end Mali-G68 GPU that shares the features of the Mali-G78, except it has 6 GPU cores instead of 24.
Before we forget, ARM also announced the Ethos-N78, which is an NPU for all those fancy AI and machine learning features. Overall, we can expect chipsets in 2021 to provide greater performance and higher energy savings. We can expect apps to run better in phones while consuming less battery at the same time.
