Of course, Qualcomm may delay Cortex-A78C and instead push a higher-clocked Cortex-A76 architecture which serves as the basis for the current Snapdragon 7c, 8c, and 8cx Gen 2s. Source: Qualcomm (Image credit: Source: Qualcomm) Qualcomm would need to take this Arm design and build it into a Snapdragon chipset by adding graphics, DSP, and more, as that's how this all works. Along with this enhanced CPU configuration, the Cortex-A78C also includes memory system improvements allowing up to 8MB of shared 元 Cache for demanding workloads, including AAA gaming, multimedia editing and other professional productivity suites.Enables high-performance computing with support for up to eight big-core-only cluster and up to 8MB 元 cache running eight threads in parallel for demanding digital immersion workloads, from all-day play to all-day productivity. The Cortex-A78C CPU is built on the foundation of the Cortex-A78 CPU as part of a scalable solution with advanced security and architecture features allowing up to eight big-core-only CPU configurations. Instead of big.LITTLE architecture, the A78-C can utilize a homogeneous structure with all big cores giving much more computing power. The Cortex-A78C is no secret, as details around it were revealed by Arm in late 2020.

The 5nm SoC would likely ship with Qualcomm's Hexagon 780 DSP (Digital Signal Processor), which serves as the basis for the popular Snapdragon 888 chipset used in smartphones.

I think Qualcomm is likely to shift to the newer and more powerful Arm Cortex-A78C platform for its Windows on ARM processors later this year. We don't know much about that chip yet, as Qualcomm hasn't announced it, but here is some informed speculation.

I could see Microsoft doing Surface Go X when Snapdragon 7c Gen 3 hits the market.
