Android Emulator 27.3.10 is now available in the Stable channel as a version number update. It contains the same change as in the 27.3.9 bugfix update:

RAM size configuration fix
  • Recently, users have reported that the emulator is slower than before. We have tracked this down to the AVD RAM size in the AVD's config.ini being set incorrectly. To mitigate this, the emulator increases the minimum RAM level for API 26+ images to the Android Studio default, 1536 MB. Please file a bug if your AVD's config.ini is not listing hw.ramSize in megabytes. The file can be found in the data directory of the AVD:
    • ~/.android/avd/<avdname>.avd/config.ini
