I listen the podcast it is before the TGA the 5th december. From 25 minutes Jason Schreirtalk about the fact Lockhart is not cancelled finally and they heard complain about the fact to release on two SKUs. And at 38 minutes he told PS5 and Xbox are very powerful and it compares it positively form what he heard from dev on the GPU side talking about Anaconda and PS5 as more powerful than RTX 2080. Interesting podcast.

So I listened to this part and this is what Jason said...
I think...I mean, I'm pretty sure, don't hold me to this up there everybody...rumormongers out there... but I'm pretty sure that the specs these high end PS5 and Anaconda are going for is more powerful then capabilities of graphics cards like RTX 2080, the stuff you can get now on the market today and they are trying to future proof it. I have heard alot of poisitive buzz about power level these guys are working with
I consider Jason to be probably best source in the industry, and if you look at this quite, I mean, its not like he has specs in his hand he is working with. He thinks they are future proof, he thinks that they are better then RTX 2080, but there is really no exact substance. He even says "Don't hold me to this one up there everybody..."
I am saying this because, difference between updated Navi for next year at around 10TF, with RT/VRS and more BW then 5700 or RX 2080, could very well end up being in that ballpark.
This is why I am "agnostic" to this issue. I think document leak we got is legit, its a snapshot of regression test during late Spring/early summer and I cannot but take it at face value. For some people 9.2TF Navi is slow. For me, even Navi 10 (with less BW then what Oberon shows) is a card only few % behind Nvidia 2070 Super.
Again, anyone can go back to Beyond3d (or any other forum) and find posts when first Oberon leaked. You will see that alot of people, who are now saying 36CU at 2.0GHz make no sense and 9-10TF is low end, sure saw alot of sense back then, because XT performance results were very impressive. That card, even with less BW then Oberon and lacking RT/VRS, decimated Vega 64 and pretty much matched R7. Only, only reason why people do not believe its real is because XSX seems to be pointing at 12TF. Thats only reason. Remove XSX, tell them improved 5700XT with more BW, RT and VRS is card that will find its way into PS5 and people would absolutely rejoice. Since XSX seems to be 12TF, we are now trying to make sense of all the vague leaks that say otherwise.
I am still waiting on complete picture, I still think PS5 is 36CU chip (so, GPU portion should be bigger then one that got into PS4/Pro), but I am willing to stay open minded and wait for confirmation or better leak. Unfortunately, current situation is such that no one actually provided ANY number bar Github. In fact, Github shown Sparkman APU during the summer when every single insider said it was cancelled back in early 2019 (so, someone like Matt and Klee), which was as we can see by data, almost certainly wrong.
Oh, and I want to add. From benchmarks I saw, overclocking Navi core is not going to yield big % gains, but memory bandwidth is. It is well worth to mention that TF per TF, Navi and Touring are ~1%. Alot of people forget it, but it is true, Navi is as good as Nvidia per TF. This is why 5700 and XT are actually closer then their TF count indicates, because per TF 5700 has more BW available.
My opinion on what is Ariel and what is Oberon is...Ariel was GFX1000. Its referred as GFX1000. Its a first Navi chip. It was referred as "Navi 10 Lite" because it was iGPU derived from Navi 10. Oberon is actual APU going to PS5, with additional features refreshed/RDNA2 chips will be getting in 2020. Ariel was used as chip to make sure BC is working, but didn't have RT/VRS and anything else PS5 will have perhaps.
This GPU, in PC space, is 251mm2. Its 10% bigger then equivalent that went into PS4Pro and 20% bigger then the one that went into PS4. This is without counting RT/VRS or any additional hardware logic going in it above what 40CU Navi has in PC space. This is also one of the things that leads me to believe Sony is going for such chip, because even "puny" 40CU Navi with RT/VRS is well above what they put in PS4 and Pro.
