He also said 8TF is needed for 4K.
Yet now 9 sucks.

*8TF with the old architecture for 4K PS4 games.
This isn't including performance improvements between architecture
12TF would be 8X base PS4
The closer the heat sink material is to the heat source the more effective it is. Heat sinks don't evenly distribute the heat amongst all the fins. The fins at the base are much hotter than the fins furthest out. Taking half of the height of the heat sink and putting it on the bottom of the chip will increase the efficiency of the material. Heat pipes help the outside fins get more heat but not anywhere near 100% efficiency, and typically are made out of copper which can be expensive.I was thinking about sony's double sided cooling patent and I was thinking is it actually a good idea?
At first glance I think "mmmm double the heatsinks + fans = double the cooling" but is this actually the case? Would just a bigger one sided heatsink and fan do just as good a job?
One advantage double sided cooling could be to have is a smaller console size, where ms just did the more obvious thing of adjusting the dimensions of there XsX.
We don't play the performance-improvements-between-architecture game. Only raw TF. It's stern but fair.
PS2's profits were lower because in 2020 you make a lot more money from the same size user base. Today Sony gets twice the revenue from a digital game than a physical copy and billions from DLC and subscriptions, it changes the revenue stream. PS2 was very profitable, don't confuse that with Sony not even trying or caring about profit just because PS4 is making a lot more money. I would actually argue the opposite, in 2020 it's much easier for Sony to lose money per console sold than in 2000. If Sony needs to sell a 450$ BOM PS5 for 399$, they will sell it for 399$.No they didn't. PS2's profits were maybe a fifth or less of PS4's even though the PS2 sold 50% more in both hardware and software. They also had PSP back then on top of that.
People insist to compare the PS1/2 period with the PS4 even though they aren't really comparable. Nothing implies that Sony is taking a hit of more than $50. Past trends don't apply when ALL major parameters have changed.
If we assume PS5 will have a more expensive SSD solution (and this forum assumes a more powerful ARM processor for decompression and an ESRAM pool) then we are assuming the XSX has a higher BOM mark while at the same time having a cheaper SSD, which widens the theoretical gap in other areas of the console, like the APU for example.We know they are likely extremely similar due to shared design goals and convergence of optimal solutions. It is unlikely a single component, whether it be RAM, storage, or APU is responsible solely for that $70 increase. It stands to reason that the APU will be some portion of it, and mm for mm, they'll have roughly equal performance unless Sony pulls significantly higher clocks out of their butt. You'd also have to presume Microsoft couldn't match those clocks.

I don't believe they would be.

Double sided cooling usually doesn't work, as the only part of the chip that makes heat is the actual silicon die, and you have a giant PCB board between that and the cooling apparatus on the back. That's why CPU's and GPU's don't cool the back - there is no point. Sony needs a very strange PCB design to make that work.
When a device is dissipating heat, there are multiple traversal options: vertical or lateral. The vast, vast majority actually moves down vertically through the semiconductor material. Semiconductors typically have much better thermal conductivity than passivation layers above (dielectrics).I think the idea of it, from the patent, is that there's conducting paths from one side of the pcb to the other, so heat can travel from both sides of the soc/die. You won't get a perfect 50/50 split of heat dissipation from top to bottom obviously, but I presume you'd only go with a solution like this in the first place if the dissipation contribution of the backside is substantial enough to make it worthwhile.

That was in reference to PS4 games. A graphical leap for PS5 is expected along with native 4K.
A 9 TF machine sounds good for a 399 priced machine but, we now know PS5 BOM is at least 450 dollars, so you're not getting a 9 TF machine.

Well this very thread has plenty of folk choosing not to accept Bloomberg so we sure the BOM is $450?m
Are we heading towards another 10 page argument where xbox fans defend the idea of a 9tf console being "enough"?So then that lends more credence to the idea 9 on new architecture doesn't suck no?
I was just providing clarification.So then that lends more credence to the idea 9 on new architecture doesn't suck no?
Like this, for example.This has been quoted out of context so often it has lost all meaning. The whole point was that ~8TF is required to match the level of visuals games achieve on the PS4 at 1080p. If games on the PS5 look exactly like PS4 games just running at a native 4K I would indeed be disappointed.
Why wouldn't it be enough? Assuming this console will hopefully be 400$Are we heading towards another 10 page argument where xbox fans defend the idea of a 9tf console being "enough"?
I'm not sure if it helps, but according to wikipedia
the PS3 RSX GPU had 400.4 GFLOPS and
the XBOX360 XENOS GPU had 240 GFLOPS
So, ....
no clue what i even try to say ;-)
Bigger boxes don't mean better cooling. A well-designed cooling system is how you go from the original Xbox One to the Xbox One S, smaller chips and doodads aside.Seems pretty silly to spend time and money on this fancy double sided cooling when they could of done the painfully obvious thing of just making the box bigger like MS did.
I'm not vegan.

The E19T is here, it is the fastest Phison controller mainstream SSD controller. It means the SSD ARM CPU is less powerful than typical high-end SSD it means more pressure on the Xbox X86 Zen 2 CPU and no DRAM, all things form the SSD will be inside RAM. For example, the translation address table is typically 10% of the SSD size here it is 1GB.
But that's the point, 3GB of LPDDR3 RAM "à la PS4" just for background apps is a waste of RAM. Just make it 4 or 6 so you can have the whole OS running off from that pool and leave the main GDDR pool just for games.
According to the RSX entry on wikipedia, it had 192 GFLOPS.

Then why make the XsX into a mini tower thicker then any console ever?
The extra thickness would allow for a taller heatsink, I don't know if a thicker heatsink is better then a thinner one but with more surface area?
According to the ps3 technical specifications entry on wikipedia, it had 400.4 GFLOPS
PlayStation 3 technical specifications - Wikipedia

But actually that number form the RSX entry makes more sense.
Damn, you can't even believe wikipedia anymore.
That is something I can't answer until we open up the XsX for ourselves ^.^Then why make the XsX into a mini tower thicker then any console ever?

It's probably cheaper? But i wonder how would a console of such size will be received by the mainstream market.Then why make the XsX into a mini tower thicker then any console ever?

Sorry, i don't understand.
So it can be quiet/silent. Just like the xbox one (original) was quiet but it was bigger than PS4 which sounds like a jet engine (at least the original model).
Silence was not a big design goal of the sxs, and they have said its about the same noise level as an 1x which is worse the OG X1 (well my 4 X1X's are!).
Phil said to the hardware team that power and performance was the goal of the XsX, to design a box dictated by this goal, that goal took precedence over everything else (apart from BOM limit)
He asked what precision the flops where measured in!

This is an enthusiast forum, so power, price and form factor are valued differently from people that buy consoles for Fornite or annual Fifa or cod.
People here ask for specs that may mean problems to reach wide audiences.
if 450 USD BOM gets u a supposedly 9TF PS5... wouldn't SEX cost >600 by that logic? Couldn't help but bringt that one up, I chuckled. Sorry :D :D :D
It's still a design goal or else everyone would be playing on vacuum cleaners.
Thank you for the explanation but ehm somehow i feel like you are talking down to me...."fancy" cooling solution is based on patents from sony about some sort of double-sided chip cooling thing. I didn't make that up. And furthermore, its the only way I see them being able to get their APU up to 1.9Ghz which is a 100Mhz lower than the leaked clocks suggest.
11.8TF GPU vs 10.7TF GPU (1.1TF difference). That around 10% difference in theoretical power. Trust me, that is going to result in identical real-world performance.
Having a 400Mhz+ PU clock advantage also doesn't mean that much in the real world. Especially when the CPUs are as powerful as they are, to begin with. And isn't "better" its more. But if you read between the lines the XSX doesn't have a separate RAM pool so of its 20GB of RAM its going to use some of that for the OS. The PS5 has a separate RAM pool (LPDDR3, again.. not making this up, both the PS4/PS4pro have DDR3RAM outside the primary GDDR5 pool.
So while the SXS has a better CPU and GPU. They are tied on the amount of available RAM for games, but the PS5 has the edge with RAMbandwidth and faster SSD. All resulting in what would be no more than a 10% advantage which means nothing at all. It's like a game runs at 48fps on the SXS, but the same game runs at 42fps on the PS5.... both games are either locked to 30fps on your screen or using VRR. Either way, it would make absolutely no difference at the end of the day.
yes and no
if Github is correct for PS5 that means they're pushing higher freqs which means worse yields.
Xbox is supposedly pushing lower freqs while potentially binning their APUS (Cloud/XSX/XSS) which means they could have way better yields.
There is a chance that despite performance disparity, the parts would cost roughly the same in the end if MS is going that route and the github leak is correct.
But there's a lot of assumptions there. Github being right is the first, Lockhart existing is another as well as binning.
He asked what precision the flops where measured in!
FP16 Half Precision
FP32 Single Precision
or FP64 Double Precision
If Lockhart doesn't exist the XSX would be crazy expensive at 56 CUs.
