Outside of Intel Phi, is there anything like an eCPU? That would be really cool, and could be exactly what we need.

Back before Thunderbolt, I used a mini-PCI-express to PCIE adapter for more GPU power. This was great for games, but I immediately became CPU-bound, which wasn't so great.

To fix this, you could have something like Big.Little but where the Big cores are external and only used when connected. Heck, then you could do something like a Big.Medium.Little architecture, where the phone's integrated Big.Little bows to the higher IPC cores in the eCPU device.

In this way, you would be able to have something that was a "soul" device that had all your settings and stuff on it, with expandable CPU & GPU computing resources. Expanded storage would also be pretty neat, but then you'd have to figure out what did and didn't need access when you were away from your "exosuit".
