Is the Big Deal about this having what used to be different cards/chips sharing a cpu-style insanely fast bus, instead of trickling stuff over pcie or dram channels? If that is the case, the advantage of this will depend on the amount of bus saturation to be eliminated. Should be interesting. Everything works on Infiniti fabric!

#12Any hardware gurus out there care to tak about how this helps? I guess having a flat pool of heterogenous resources is nice. As long as there’s a decent SDK that abstracts the hard stuff away I’m all for it.

I don't think that's even needed. I just assume what you'll see from inside the program is some resources connected to some sort of very fast interconnect. It's nowhere near what Cell was - a really bad barrel-like PPC core that had to manage DMA to feed a bunch of marginally-smarter-than-DSP cores (with an incompatible ISA, obviously) that had no access to the main memory.

#13What's the difference between chiplets and SoCs?
This looks like a step above what Octavo does with the Sitara cores.

The chiplets are separate pieces of silicon linked together by a larger chip, whereas SOCs are etched onto one large piece of silicon?
Sounds somewhat similar to what Intel started offering recently, in collaboration with AMD. Basically a Intel CPU and an AMD GPU in a single package, for use in laptops that needed something beefier than an Intel GPU but didn't have the volume allowance for a full GPU card.

Pointing to one example of someone failing to do something in the past is not strong evidence it won’t happen this time. If anything there was lessons learned from that failure.

That’s the advantage over having multiple packaged chip on a traditional PCB. The advantage over an SoC is that you can have different subsystems on decoupled development schedules and different process nodes all come together on the same “chip.”

They also have a budget Ryzen that does the same thing but with their own Vega graphics. I am using one now for web development and distributed ledger development.

#18I think would be interesting to see someone like Mellanox make a chiplet with their tech which could be fully integrated into an AMD SoC or APU or whatever they're calling them now.

#19Will this still allow modular builds or it will require buying a single board with everything soldered to it?

I figured those where made much like their APUs of previous years, meaning that it was all on a single die.
