The 7% boost or higher clock speed and memory bandwidth was needed to absorb the extra cost of rendering to a HDR output buffer, 10 bit instead of 8 bit.
HMDI 1.4 also supports 10 bit (and 12 bit color) however not HDR 10, the new format used by 4K tvs for HDR. The ps4 and original XBox One could already output games in 10 bit (and 4K 30fps), yet without the extra brightness range that HDR allows. HDMI 2.0 is needed for HDR. (And HDCP 2.0 DRM for video content)
The 20nm planar die shrink failed. XBox One S is now using 16nm finfet which keeps the cost up for now. The release of the 500GB model is likely delayed due to very low to no profit margins, get the hardcore to buy the profitable 2GB model first. Perhaps the slight increase in clock speed is also to compensate for any low level differences between planar and finfet architecture, but that's pure speculation on my part.
Anyway it's good news for the price of the Neo. Without the esram its gpu shouldn't be much more expensive than the 16nm redesign in the XBox One S. Maybe even cheaper as it's a standard component. Neo is partly due to the die shrink problems, we should have cheaper slims already and the relatively higher cost of the delayed slims worked in favor of a mid gen refresh.

Oh ok thanks that makes much more sense now.
But this brings me to another question.....
If sony is going first with the Neo, does that mean they keep making the base PS4 at 28nm? and for how long? Cause I'm guessing they go with the Neo for now then eventually do a 16nm version of the core PS4 APU further down the road.

Sony said they would keep the base ps4 around for the rest of the gen, dunno if there's any point in making a 16nm version of it. I imagine the Neo will quickly become cheaper to produce than the older tech and slowly replace the base ps4. Why make things harder by introducing yet another hardware spec for QA.
My guess is all this stuff of base ps4 will stick around and the xbox one S has no influence on performance is all PR so people won't stop buying the base consoles until the successors are freely available.
