ARM unveils Cortex-A75, a new high-performance processor to power laptops

ARM today announced DynamIQ technology that will change the multi-core ARM experience across a greater range of devices from edge to cloud across a secure, common platform. Today, they announced two new processors based on DynamIQ technology.

The new Cortex-A75 processor a massive 50 percent uplift in performance and greater multicore capabilities. This will enable SoC vendors like Qualcomm to address multiple high-performance use cases including laptops within a smartphone power profile. Cortex-A75 offers 20% more performance over the Cortex-A73 when compared at same frequencies.

  • Superscalar processor core, decoding, issuing and executing more instructions than our previous generations. Full out-of-order processing, non-blocking high-throughput L1 caches and advanced instruction and data prefetching.
  • Private L2 caches close to the processing cores. Configurable in size, these private L2s shorten latencies to memory and keep workloads closer to the cores for faster processing and lower power consumption.
  • Unified shared L3 cache in the DynamIQ Shared Unit (DSU) that can be used across all processors in the cluster, including the Cortex-A75 and Cortex-A55.

SoC vendors like Qualcomm can use the Cortex-A75 either standalone with up to 4 high-performance processors, or in big.LITTLE combination with the Cortex-A55 processor, with up to 8 processors total depending on the tradeoffs between performance levels and cost. Along with the new Cortex processors, ARM today also announced the latest premium version of the world’s No. 1 shipping GPU, the Mali-G72. The new Mali-G72 graphics processor is based on the Bifrost architecture and it is designed for the new and demanding use cases of ML on device, as well as High Fidelity mobile gaming and mobile VR.

Initial devices based on the new Cortex processors will be shipping in early 2018. At Computex 2017 this week, Microsoft and Qualcomm are expected to reveal more about Windows on ARM. Hopefully, we will soon see some Qualcomm-based Windows laptops in the market.
