Qualcomm’s System Level Architecture in the Snapdragon X2 Elite (opens the original)
Read excerpt
Laptop chips have gotten very powerful in recent years, with increasing CPU core counts, more powerful iGPUs, and higher DRAM bandwidth to feed that compute. All of that creates pressure on the chip’s system level architecture, which must deliver high bandwidth, service an increasing number of blocks, and keep latency under control. Qualcomm’s Snapdragon X2 Elite Extreme is a good example of how powerful recent laptop chips have become, with 18 CPU cores and an iGPU packing nearly as much comput
On Binary Translation and its Consequences (opens the original)
Read excerpt
The PC market is one of the toughest areas for a CPU designer to compete in. Consumers in the PC segment expect high performance across a wide range of applications, and famously expect their devices to reach beyond a constrained, curated set of use cases. Microsoft’s own Surface RT prominently failed more than a decade ago because it could not run the programs that PC users expect to just work on Windows. Recent 64-bit Arm cores from Qualcomm and others are fast enough to satisfy the performanc
Arm’s C2-Ultra, G2-Ultra NX, and CSS N4 IP (opens the original)
Read excerpt
Editor’s Note (9/8/2026): Arm has reached out to clarify that the maximum IPC increase of the C2-Ultra core over the C1-Ultra core using the parameters shown in the endnotes is 7% along with the memory bandwidth improvement not factoring into the IPC improvement. The article has been edited accordingly.Hello you fine Internet folks,While Arm’s last announcement was about their new datacenter focused CPU, the Arm AGI CPU. Their latest set of announcements bring a much wider focus. The incoming C2

Hot Chips 2026: Fujitsu’s Monaka CPU (opens the original)
Read excerpt
Fujitsu’s A64FX was a pivotal core. For the Arm ecosystem, it introduced SVE. SVE continues to define Arm’s vector execution strategy to this day, with newer extensions like SME adopting a similar vector length agnostic approach. For Fujitsu, A64FX marked a shift away from SPARC and towards the 64-bit Arm ISA (aarch64). Adopting aarch64 let Fujitsu take advantage of a stronger, better supported software ecosystem. Because there’s a lot more Arm software out there than SPARC software, the shift a
