Arm is Developing the Next-Generation Cortex-X5 CPU Core
On January 15th, it has been confirmed that Arm is developing a new generation of Cortex-X CPU core, codenamed “Blackhawk”, expected to be named Cortex-X5. This new core is one of Arm CEO Rene Haas’s key focuses, aiming to narrow the gap with Apple’s self-developed CPU cores as much as possible, and even surpass them.
Although Apple’s self-developed cores also use the Arm instruction set, they outperform the standard Arm cores due to superior design capabilities and ecosystem support.
According to Arm’s estimates, Cortex-X5 is expected to bring a huge performance boost, achieving the largest IPC (instructions per cycle) improvement in five years.
Interestingly, the existing big core, Cortex-X4, was also touted as the “fastest Arm CPU ever” at its release, boasting a 15% performance improvement over its predecessor while reducing power consumption by 40%.
Cortex-X5 is expected to be commercially available by the end of 2024 or early 2025, competing with Apple’s A18 and Qualcomm Snapdragon 8 Gen4.
The Snapdragon 8 Gen4 will be Qualcomm’s self-developed CPU core based on the Arm instruction set.
