ARM has unveiled new CPU and GPU designs that the company says will bring better performance to next-gen smartphones, tablets and laptops while. The new designs are also more energy efficient, which could lead to longer battery life… or at least better performance without taking a bigger toll on battery life.

The ARM Total Compute Solutions 2023 (TSC23) platform introduces three new CPU designs, next-gen graphics, and new technology that helps them all work together.

ARM’s new highest-performance CPU design is the Cortex-X4, which the company says offers 15% better performance than Cortex-X3, while using 40% less power. That said, it takes up about 10% more physical space.

You probably won’t see processors with only Cortex-X4 CPU cores though. Like earlier Cortex-X CPU cores, it’s meant to be paired with big.LITTLE cores, and ARM has new versions of those as well.

The Cortex-A720 big cores brings a 20% improvement in power efficiency over the previous generation, while Cortex-A520 promises a 22% improvement. Interestingly ARM isn’t saying anything about performance gains here, but improvements in performance-per-watt can typically either be used to offer the same of performance while consuming less power or better performance at the same power level.

ARM is also introducing the Immortalis-G720 GPU, which the company says is based on ARM’s 5th-gen GPU architecture that will serve as the foundation for the next few generations of graphics processors.

Immortalis-G720 should bring a 15% boost in performance, 40% reduction in memory bandwidth usage, as well as improved power efficiency: ARM says it’s the company’s “most efficient GPU architecture ever,” and also introduces new technologies including Deferred Vertex Shading.

ARM is also introducing new Mali-G720 and G-620 GPU designs that will likely show up in cheaper, lower performance processors.

TSC23 also features a new DSU-120 “DynamicIQ Shared Unit” that allocates resources between CPU cores for multi-threaded tasks.

The company’s presentation also teases some code-names for the next-gen CPU and GPU technologies coming in 2024:

  • “Blackhawk” will be the successor to Cortex-X4
  • “Chaberton” will follow Cortex-A720
  • “Hayes” will follow Cortex-A520
  • “Krake” will follow Immortalis-G720

There are no details about performance, efficiency, or new features for those next-gen technologies though.

    1. I do hope so. Personally I don’t care so much about it closing the gap with ARM, but with x86.

    1. What are you trying to run an external gpu with a phone LOL. Lets be real. USB4 is not needed on a phone, or any device these would be put in.

    2. This is a reference design for CPU and GPU cores. There are no such thing as an ARM made SoC. Whoever licences and implements the cores can add their interconnect, PCIe, audio, radios and I/O handling and decide to get a different GPU as well (like Qualcomm and nvidia does).
