Not a fair comparison.
Do you also remove L2/L3 die space from Zen 2 chiplets?
Why would they use different DRAM chips?
PS4 Pro and XB1X have set a historical precedent by using the exact same type of GDDR5 (6.8 Gbps). Have you forgotten that? There will be no GDDR5 vs DDR3 clusterfuck this time around, both consoles will be more similar than ever before.
Also, your "perfect mem bw" theory (448GB/s (GPU) + 64GB/s (CPU)) is a bit off because of this (it affects EVERY architecture with unified memory):
New information reveals that the actual bandwidth of the Sony PS4 is 140GB/s instead of 176GB/s as previously stated.

PS4 final APU dev kits were delivered in January 2013:
Sony and Microsoft have had a lot of work with Orbis and Durango. Create a new hardware it’s a long running process, you have to build different versions of hardware and make changes along the core until the last version, the closer one to the retail product. We have created an article with...

Power consumption can easily be measured with a watt-o-meter.
Then again, I don't think we'll see the final APU chips before January 2020, so gotta have patience for another 6+ months.
HBM3 will be the first, affordable iteration, since it uses an organic interposer (vs silicon, which is a lot more expensive):
Plus, Samsung unveils GDDR6 and “low cost” HBM technologies.

Samsung wants to push HBM3 to the high end of the market and adapt the technology to serve lower-cost segments more effectively. Combined, the two approaches could revolutionize memory bandwidth in the next few years.

Apparently it will be available sometime in 2019 or 2020. Not sure if it can be mass produced or not, at best maybe Sony could use 32GB.
Personally, I'm sticking to 24GB GDDR6 384-bit, since it's a safe bet. I wouldn't mind being proven wrong by a 2013-style megaton though.
You're welcome.
Calm your tits though, we don't know if it was Cerny who designed the Aeolia southbridge. Marvell was involved with that.
AFAIK, Cerny is not a chip designer per se:
I've removed the names for anonymity reasons, so don't ask me who that guy is.
I'll just tell you that he has a lot of contacts in the
silicon industry.
nVidia cards have this kind of magic, which Navi doesn't have (still waiting for that "Maxwell sauce"):
Looking back on NVIDIA's GDC presentation, perhaps one of the most interesting aspects approached was the implementation of tile-based rendering on NVIDIA's post-Maxwell architectures. This has been an adaptation of typically mobile approaches to graphics rendering which keeps their specific...

Nintendo is a much smaller company than either Sony or MS and they have already found a solution:
The consoles failed to make an appearance at E3 but could launch soon

We had this discussion when the original PS4 came out. Just go my PS4 Pro and it's made in China, my original PS4 was made in Japan. Just curious to see if there are any Pro's from Japan, check the bottom of your box.

I think you meant to say Giga Rays.
They're not gonna make use of FP32 shader ALUs for SW RT. SonGoku posted a relevant pic straight from AMD.
