In May of this year, ARM officially announced the latest generation of mobile processor architecture Cortex-A78, as well as GPU Mali-G78, NPU Ehos N78, etc. Among them, Cortex-A78 supports Big and Little hybrid devices such as 4 large cores and 4 small cores, taking into account performance and power consumption.
However, for the notebook field that ARM is about to enter, A78 is somewhat helpless when facing new platforms with higher power consumption.
In response to such a problem, ARM recently released a new Cortex-A78C architecture, optimized for high-performance computing platforms, mainly for notebook products.
Under the Cortex-A78C architecture, chip manufacturers can configure up to 8 large cores, and the third-level cache has been expanded to an astonishing 8MB, which can also meet high-performance load scenarios such as 3A games and productivity.
At the same time, Cortex-A78C has also been updated in terms of data and device security. A key feature is the function pointer check (PAC), which allows the CPU to correct whether the function pointer is correct when executing a jump to prevent the jump from being artificially modified. .
This feature can significantly reduce the probability of being attacked, reducing vulnerabilities for return programs by more than 60% and vulnerabilities for jumps by more than 40%.
Not long ago, ARM also released the Cortex-A78AE, an architecture optimized for autonomous driving scenarios. It must be admitted that ARM has a very long-term vision. As Apple Mac products move towards the ARM lineup, the ARM ecosystem of Windows will also be driven. In the future, A78C CPUs from Qualcomm, MediaTek, Samsung and other brands may soon meet us. Not long ago, the traditional chip giant Intel just lost 100 billion in market value, and this time it is even more at a loss.
