Yep, it contains a more detailed description on how to use the individual memory access pathways.
By the way, this quote here
is, as far as I understand it correctly, something the PS4 can do but the XB1 can't. At least the other leaked documents on vgleaks state that the XB1's GPU caches have to be flushed completely.
what's the point of this again? It seems only the sony first parties will utilize these features
What flavour is this secret sauce?

Considering how much we see you bitching about whether the 1st party games look good enough, I would think that'd be important to you.what's the point of this again? It seems only the sony first parties will utilize these features
The below is what this thread will become:
What is hUMA though?

It's time for my lunch.
Basically:
Memory used by cpu and gpu without additional copying.
Its far more complicated than that, but that's essentially what it is, every time something is copied from one place to the other it slows the system down and hUMA prevents this from happening so GPGPU in particular is far more efficient.

Shit for a second i was fooled again.
Impressive demo.
This is not the whole story because the XBONE has a single address space that both the GPU and the CPU use. What the XBONE seems to be lacking is the decent way of flushing the cache of the GPU that the PS4 has, meaning that any coherent access between the CPU and GPU on the XBONE will be more expensive (assuming it has to flush its entire cache).
The nice thing is that most of the PS4 custom features are relatively easy to use so third parties won't have to put too much effort into utilizing it but first parties will do it sooner. Besides, giving Sony first party every advantage possible is a good enough reason anyway.what's the point of this again? It seems only the sony first parties will utilize these features

So was this true or not? IT seems like word keeps going back and forth on it.

Digital Foundry: I seem to recall you might have talked about a toolchain where code could be compiled either for CPU or GPU. Is that right or have I got that completely wrong?
Mark Cerny: Such a toolchain does exist. It's AMD's HSA [Heterogeneous System Architecture]. That's very exciting but our current strategies are about exposing the low-level aspects of the GPU to a higher-level language. We think that's where the greatest benefit is in year one.
