SSD is soldered to the board. With only 8GB you’ll be using the swap partiton a lot so for anything exceeding 8GB of RAM you will be using the SSD as a slower “RAM” which will wear it’s lifespan down by constantly writing/reading into it’ s swap partition.
I don’t like it. I think going from slightly slower vs 7800X3D at just 65W TDP is much better than doubling that just to match it or slightly beat it… And at the end of the day it will be the 9800X3D that’s supposed to compete with 7800X3D anyways.
