I'm curious if they even considered the A78C, the variant with a similar cache (except L2) that replaces all LITTLE cores with big and possibly costs less to license as it's probably a roadmap core like the A78. It's chronologically a step behind but could unlock better performance (than A78+55) with a negligible/nonexistent hit to battery life.
- my123 5y agoSnapdragon 8cx Gen 3 is 4xX1 + 4xA78, with no A55s.
- PennRobotics 5y agoI eat my statement. That looks like a better configuration than an octa-A78C, but only if the licensing cost is the same or you REALLY have a need for the latest extensions.
- my123 5y agoSo, it actually is X1C and A78C. https://blogs.windows.com/windowsexperience/2022/02/28/mwc-2022-the-next-microsoft-pluton-device-pac-technology/ https://blogs.windows.com/windowsexperience/2022/02/28/mwc-2... references PAC support, which is only in the C variant of those cores.
- PennRobotics 5y agoGood catch. I wasn't even aware there was an X1C! Then again, my daily driver is a 1 or 2 core Cortex-M. On special occasions (once a month or so) something more exotic lands on my desk.
