ARM delivers major performance and efficiency gains with their latest CPU cores
ARM showcases impressive gains with their Cortex-X925 and Cortex-A725 ARMv9 CPU cores
ARM has today revealed two new CPU core designs, both of which promise major performance and efficiency gains over their predecessors. Replacing the ARM Cortex X4 is the new Cortex-X925, which promises users up to a 36% boost in single-threaded performance. Additionally, ARM has revealed their Cortex-A725 core, which replaces their Cortex-A720 core. This new mid-range core delivers up to 35% more “performance efficiency” than its predecessor.
All of these new core ready to be taped out on new 3nm lithography nodes, making them ready for the next round of ARM-based devices. On the high-end, ARM’s Cortex-X925 CPU core delivers tremendous performance gains for users, touting a 50% increase in TOPs for AI. On top of that, this new core is more efficient than the Cortex-X4 and can be configured with up to 3MB of L2 cache.
The new Cortex-A725 core focuses more on efficiency improvements than raw performance increases. The core design is 25% more efficient than its predecessor and can deliver more performance at any wattage category. ARM has stated that this new core design features some major L3 cache improvements. These changes result in a 20% improvement in cache traffic.
Alongside the X925 and the A725 we have the refreshed ARM Cortex-A520. While this is not a new core design from ARM, it is a new implementation that can be used with 3nm lithography nodes. This new implementation of the A520 can deliver users up to 15% energy savings. Not bad considering this isn’t a new core design. That’s great news for any0ne that wants a longer battery life from their devices.
With their new high-end Cortex X-series cores, ARM have delivered some major performance improvements. This is a big deal form ARM. This change will boost the appeal of ARM for future server and PC processors. With Microsoft and Qualcomm pushing Windows on ARM, it makes sense for ARM to work on more performant CPU cores.
