Arm has revealed 2022 Total Compute Solutions (TCS22), its next-generation CPU and GPU designs for mobile devices including phones, with a focus on improved mobile gaming performance. All-around performance of this year's solution is up to 28% better, with up to 16% power reduction. The new second generation Armv9 CPUs are designed to improve performance, efficiency, and scalability across the board, but "especially for gaming". Complementing those are a new range of Arm GPUs for advanced 3D graphics, including a new Immortalis brand for flagship GPUs that are even more powerful than the Mali line. The Immortalis-G715 is the first Arm GPU to offer hardware-based ray tracing support on mobile, while the new Mali-G715 supports Variable Rate Shading. The new Mali-G615 improves on the Mali-G610 and rounds out the lineup. All of the new GPUs offer a 15% performance improvement compared to the previous generation. On the CPU side, the new Arm Cortex-X3 delivers "a 25% performance improvement compared to the latest Android flagship smartphone". The new Cortex-A715 replaces the A710, offering 20% better energy efficiency and 5% better performance. For context, this matches the performance of the Cortex-X1. Meanwhile, an updated Cortex-A510 "little" core offers a 5% power reduction. A newly updated DSU-110 interconnect supports 50% more CPU cores (up to 12) and supports a high number of Cortex-X3 cores. With TCS22, Arm is also introducing two new security technologies to address memory safety vulnerabilities: Asymmetric Memory Tagging Extension (MTE) and Enhanced Privileged Access Never (EPAN). Apple, Qualcomm, MediaTek, Samsung, and Google all use Arm's designs and technology as a starting point for their own processor chips that power essentially all of today's phones.
