With two channels you could have more memory pages open at any one time. Also, CPUs aren't the only memory users in these unified memory systems, there's graphics, sound, cameras, I/O, wireless networking and so forth, so having two independent memory channels would result in less contention overall I would think.
Apple A9 SoC

OT
But, I was replying to your assertion that the A53 better suits the need of the Apple Watch than a ARM A7. The Apple S1 uses a single core processor, and WatchOS is 32-bit so the extra 64-bit silicon in the A53 is wasted. Perf/w of the A53 is worse than the A7, so higher IPC may not be any use if it causes overall power requirements to increase, in such a power constrained package. As the Apple Watch partially offloads processing to its companion iPhone , it kinda obviates the need for phone class SoC performance, just my 2 cents
WatchOS 2 supports entirely native apps (restricted by hardware limitations of course, such as need for iPhone's cellular modem for internet connection when no wifi is available, for example.) And whether wOS is 32-bit or not is entirely up to Apple's whims - undoubtedly at some point in the future it will migrate to 64-bit, just as other iOS devices have.
Original iPad had only 2Gflop shader performance? Holy friggin hell, how is that even possible?

Xcode seems to confirm 2GB RAM for the iPhone 6s and 6s Plus and 4 GB for the iPad Pro. Peek and Pop in the new iPhones wouldn't be very effective as a time saving shortcut to briefly interact with another function or app if you had to wait for the original screen to reload on return due to lack of RAM.

I wonder if using the pen (sorry, "pencil") will enable peek&pop on the ipad pro or not...
Maybe the next version will have full force touch (sorry, "3D touch") for the entire display. *shrug*
That's the deal with gadgets. They always gotta hold something back for next year, to make you wanna upgrade.

They are part of the new 3D Touch functions. For instance if you medium-press "Peek" on a link in an email in Mail, a mini-Safari overlay will open so you can preview that website. If you start pressing harder or you did a hard press to begin with, you activate "Pop" which brings up a full screen Safari instance to that link. There is then a shortcut at the top left to return to the calling app, in this case Mail. It's kind of a contextual fast-app switching/multitasking and of course works better with more RAM so things don't have to reload as you're switching back and forth.
it's not the entire display? how is the support area defined? just like the lower part of the screen for the thumb? I got the impression (by the presentation) it was for the entire display.
next is to give the display a texture that you can feel with your fingers. apple filed that patent at the same time as the multi-level touch patent, if I recall correctly.That's the deal with gadgets. They always gotta hold something back for next year, to make you wanna upgrade.
iPad Pro doesn't seem to support "3D Touch" though.
oh, I thought he was referring to the phone, pardon!
My bad... I just meant to say maybe it will support "3d touch" without having to use the pen.
AFAIK, ipad pro's display doesn't support force sensitivity at all; only standard capacitive multitouch.
I don't think so. The pencil only seems to sense/transmit pressure and angle, while the capacitive screen detects coordinates.
Or they could do four smaller ones in/near each corner of the device for example.
