It's way too early to guess "flops" count right now, too much misinformation going around. The one strategy i'm really liking from xbox here is the dual sku approach though. I'm way into the idea of being able to pay a premium for premium hardware. I'm historically more partial to Sony 1st party software, so if they would copy MS's strategy in releasing a beefy version of the ps5 at launch I'd be all over that.

perhaps amd is extremely confident in their 7nm++ process to justify such high CU count, that would be excellent news for all, including pc gamers

Hmm... It looks like someone just copied the specs for the current Radeon RX 5700 graphics cards and Ryzen 3800X CPU from Wikipedia.

I don't know what "custom" means in this context, but why bother fiddling with AMD's perfectly adequate PC design?

2- ray tracing will be a performance killer, you can look at current pc benchmarks to see that. the difference will be much more noticeable than the pixel count of current gen, which i agree, i don't particularly mind the 1440 upscale vs 4k done in the 2 consoles

56 CUs in the Series X would be insane, even more so than pushing AMD GPUs to 2000 MHz. 400mm²+ on 7 nm ain't going to be cheap chief. But the leaks from Taiwan seemed to point out a ~350 mm² APU for the Series X (broadly consistent with the mock-up images Microsoft divulged) versus a 300 mm² APU for the PS5. That to me indicates room for no more than 48 CUs, so who knows if that's indeed the case. By the way, if RT isn't included in the PS5's APU, it doesn't mean there isn't a custom chip dedicated to it. Cerny confirmed there will be a hardware solution, so I wouldn't be concerned about this particular point.

Both are using RDNA, and  that already 100% confirmed, If one of them choose GCN instead RDNA that will be foolish. Even Lisa Su from AMD made that statement at E3 2019 and CES 2019 th. Sony  next gen machine will be using Navi, the same thing also happen when Phil Spencer shows at CES 2019 at AMD press conference when he explained that Xbox will be using Navi (RDNA).

If this leak is accurate... The Playstation 5 will be 9.2 Teraflops, the Xbox Series X will be 12.1 Teraflops.
Not that I hold much weight in those numbers.

But you are right, there could be some more changes we aren't privvy to... I.E. 128 Shaders per Compute Unit rather than 64. (Albeit very unlikely.)
That would then put the PS5 at 18.4 Teraflops.

Again, unlikely though, that would require allot of expensive redesigning of Navi and no one is going to do that.

We don't know the impact Ray Tracing will have on performance as AMD has never released a GPU with dedicated hardware ray tracing cores before.

Not sure how many times it has to be said, but I'll say it, again, MS=/=Xbox. MS is not going to give Xbox the budget to lose them billions by taking a $200+ loss on HW, not when they are focusing on services as their future. You think the shareholders were loud at the beginning of this gen, they would be 10x louder at the beginning of next gen.

PlayStation, on the other hand, is one of Sony's top priorities. They are going to make sure it sells. And if that means taking a deeper loss on HW, then so be it. And I think plan on it, hence why the PS4 isn't already $199. They're building up a profit buffer. 

1)Who said anything about $200 loss? You think the series X will cost them $600-650 just to make?

2) Even if they did, let's say, take that big of a loss, in the long run people that buy consoles buy video games and on Xbox there is a great chance they subscribe to Xbox gold as well as Gamepass. Subscriptions are what Microsoft's bread and butter is now, Office suite demonstrates this. If they could lose that much on the console sales, they will no doubt still be turning a profit within a year or so with each of those customers, many well before that.

3) Microsoft's massive cash means they could do this sort of thing better than Sony. If they can lose $100 million on consoles, but by doing so capture more of the market to then make $200 million or more on subscriptions down the road that is worth it. Sony's failed businesses  in other avenues makes them with less cash to take this sort of short term risk/long term gain.

Yes, it would make one's favorite toy run at 45 instead of 58 frames per second in the same game.

Gasp, the horror!
