Quoting myself ~1 hour ago:
Good point, but here's a question: when would Sony have come to this conclusion? It would not have been early 2017, because that's not enough time to gauge PS4 Pro's overall market performance. In fact I don't think it would've been 2017 at all, because they maybe would've wanted to see the X's performance relative to that ecosystem's base, to see if they did things better than them and what-have-you.
I think any change in PS5 spec plans would have started in mid-2018. That still doesn't explain the Ariel/Oberon testing going on well past that date (I have my own theories to that however), but that would probably give Sony about 1.5 years from today to be working on this hypothetical other PS5.
Other option is that they've had two different PS5 specs in development the whole time but the less conservative one was behind in development on purpose just in case they saw favorable PS4 Pro results and concluded that a $399 PS5 was the right idea all along because they could do a PS5 Pro later in the gen. So by sometime in mid-2018, they conclude mid-gen refresh isn't the way to go, so they accelerate development of the beefier PS5 spec that was purposefully held back, and they've been working on that the past 1.5 years as the main design.
But that still wouldn't explain Oberon chip testing as late as mid-20
19 (if not even later than that). Again, I have theories on that, but they're beside the point. And there hasn't been any benchmark datamining revealing this other beefier PS5 chip yet, either (which is more worrying imo).
summer of 2018, Charlie Demerjian leaks ps5 info on Semiaccurate. This is the guy who broke the story of nintendo going with nvidia, ps4 specs in 2012, and sonys plan for pspro in 2013. Guy isnt 100%, but he is connected in silicon world. He stated a large number of sony dev kits went out in 2018, indicating a 2019 launch.. there were so many kits out that he thought they could have done a 2018 launch if they had to, he DID NOT predict a 2018, 2019 was the year.
Assuming that is true, Oberon was the 2019 chip. Since they did not release a 2019 console, Something changed between summer of 2018 and 2019, and sony shifted to a 2020 date.
Most likely they saw MS' plan for a huge chip based on superior tech on a smaller node with hugely marketable things like RT (2019 Oberon would not have had RT), as well as Microsoft's plans for a cheap box.
2019 PS5 would look like crap come holiday 2020, and for the next six years, and they couldn't just lower the price because of lockhart, which would also have things like RT. So they scrambled, and paid AMD to fast track their own competitive 2020 chip. Very expensive, but necessary.
this would explain sony's silence in 2019 and yesterday's story about sony having to shift third party games around 2 years ago.
So whats up with github oberon still being tested and worked on as late as summer 2019? It is sony's version of lockhart. Maybe Oberon is dead or maybe it is coming as ps5 weaksauce, but github does not mean a 8-9 TF ps5.
all is good.
I like this; all we need now are benchmarks leaks for this other PS5 chip to confirm its existence. But the fact it hasn't happened yet makes me wonder if they can get it completed in time for a 2020 launch. I know that AestheticGamer guy walked back his comments, but I think that could still be a possible outcome.
This could somewhat comfortably explain Oberon's late (possibly ongoing) testing, but if that's indeed going to be their Lockhart, it'll be..."
interesting"...to see if the same people complaining about Lockhart holding XSX back will do the same about Oberon holding PS5 back. Since, you know, conceptually they're very similar. (I was even one of those one thinking prior about Lockhart holding XSX back, but some research into the efficiency of scalable assets and logic have made me walk back a lot of those worries. Not all of them, but most of them).
