The chart didn't load for me. Wasn't on my main computer. I see it now. The Linus video tends to disagree with the chart though. And my personal experience does as well. But you did say it was a rough estimate so, oh well. But what's the source of the info on the chart?

Edit: Also, I really don't think you've addressed the FPS beats resolution argument.

Sony can get a far larger discount since their console sells 100 million+ while Xbox is half of that. Sony also has the funds easily to eat a loss: they've been making billions of profit every year (far more than Xbox) and have far higher software sales, subscription sales and 1st party sales. 

MS aren't going to burn all that money on a business that makes them a fraction of the money. By this insane logic, Google and MS would win at every market they compete in as they can burn so much more money.

Sony has a console that sells 100 million while MS is declining and selling 50 million. Sony is going to get the better deal from AMD.

AMD will give Sony larger discounts as Sony has a history of consoles selling near 100 million. Avg cost decreases as output increase. Read the article. 

I'm sure Series X will be a bit more powerful. Though, I'm curious what it will cost and if its meant to be a mass market product or more of a niche product like MS's $200 Elite controller. My guess is that Series X will be $599 and that's me being conservative. Sony will want to sell as many ps5's as possible and no doubt aim for a more tolerable price point between $399 -$499 and it'll likely be around 9 to 10Tflops. In real life performance, the games will probably end up looking quite similar between the 2, with Series X games running at a slightly higher res that most people won't notice.

On the other hand, if the ps5 was weaker compared to the Series X, it wouldn't make much sense to do their ps5 tech reveal right after. They must be pretty confident in how the 2 compare so who knows, maybe Sony has some tricks up their sleeves. 

Likely this reveal was planned ahead of time and Sony had no idea MS would drop theirs on monday. Either way, the Playstation reveal is for fans of Playstation (there are over 100m) and ultimately its independent from whatever MS is doing. Sony is feeding the needs of their core audience by giving them a tech breakdown even if its 2Tflops less then what MS showed yesterday. 

155 - 90 = 65

90 - 50 = 40

Well, i wonder, which side dropped more. I think you already knew.

You are welcome.

It's just simple math... It's using the Pixels Per Degree formula which accounts for resolution, size and distance.
It's what Apple would use for it's "retina" display branding... And obviously can be scaled up from there.

Sony cannot guarantee anything, they have sold any consoles yet.
Sony has also had multiple consoles sell less than 100+ million lifetime... Such as the Playstation 3, Playstation Vita, Playstation Portable.

The PC minimizes the financial risk to Microsoft's game division.

Sony hasn't even revealed their console yet, let alone sold a single unit... It could be a giant cock-up and a catastrophic flop with a plethora of anti-consumer stances that draws ire from the entire industry. (Unlikely, but companies make mistakes! Ask Nintendo, Microsoft, Sega etc'.)

Just don't count your chickens before the eggs have hatched.

Does not work like that I am afraid.

Microsoft and Sony pay AMD a 'Lump Sum' for the chip design, R&D and other work. - They then pay licensing fees on a regular basis after the fact.

From there... Sony and Microsoft will pay for chips in "batches" fro various foundries. - They don't forward project 100~ million units, that would be business suicide... And especially as the chips themselves will undergo multiple revisions/respins in order to resolve eratas and so forth, plus die-shrinks on top of it.
Microsoft and Sony will *never* order 100~ million of the same chip because they will never sell 100~ million of the same chip, even the Playstation 2 with 150~ million consoles sold, did NOT sell 150~ million of the same chip.

Take the Nintendo Switch as another example, the new Switch consoles don't use the same chip as the launch console, it's an entirely new variant with entirely new manufacturing and licensing agreements in place.

So before you demand people to "start reading" it does help if the information you provide actually has any factual basis to start with.
