What's so odd about that? When the PS4 and Xbox One came in 2013 they were weaker than a GTX 670 from the year before.

in real world condition how many 57000xt (even reference desing) is running at 8.22 tf ?

Would you be satisfied if the PS5 is 399$ ?
Pricing will be a huge factor this generation (console war).

Are these real numbers or are you just taking guesses?
Why would the GPU ever need to drop below 2Ghz?

Dunno. Never seen such benchmarks.
But I do know that all the TF numbers of all the GPUs till now were in "boosted" TFs and nobody was whining.

I prefer Microsoft's transparency to Sony's secret sauce. Everything feels like an inverse to 2013.

You'll see.
Smartshift is used in mobile devices where they're limited to a certain TDP. Chips in mobile drops by over 50% in clocks to boost the other parts. It's not something you use for a mere 10% or even 20% variance in clocks.
CPU and GPUs have a optimal sweet spot. Moving past those sweets spots add diminish returns up really quickly.

I wish people would read: https://www.pcworld.com/article/353...ectstorage-velocity-architecture-windows.html
To me the most impressive part is how the expansion slot directly augments the internal storage. I guess the slot is directly tied to PCI lane, no other explanation. Has that been done before by a PC maker?

For all the talk of how «meaningless» the number of TF is, Sony had to use every trick imaginable to achieve that double digits number, even if it is just on paper.

seems comon sense to me you don't whine when you hardware can perform better than what is advertised.
the reverse ....not same story

they have to justify that 16% advantage

I swear some of the shit I read on Youtube video comments... holy crap makes Resetera seem tame.
And if the reverse never happened, why the concern?

Don't worry Xbox fans. XSX is better than PS5 in every segment. Even SSD.

Not true. PS5 has a better SSD. But that's basically it.

then why is the advertised frequency not fixed or the minimal guaranted ?
dunno if you are gullible here or if it's bad faith.

It is actually better in everything but the SSD and when combined with the variable clock speeds that Sony had to use to reach the damned double digits TF number, the difference becomes even bigger.

PlayStation blog:
Variable frequency, up to 3.5 GHz
Variable frequency, up to 2.23 GHz (10.3 TFLOPS)
Variable/fixed is self explanatory.
Make of it what you will:

Titanic was called the Ship of Dreams, and it was. It really was.
I just watched Digital Foundry's analysis of Gears 5 demo on Xbox Series X.
And, my God! That's supposed to be a generational leap? I can barely see the difference! Even side to side.
It's gonna take a lot of brainwashing, and great games, to make the world buy these new consoles for more than $300. Good luck Sony & Microsoft. I wish you both well.

It is not fixed or guaranteed in any other GPU. Apart from MSFT PR for XSeX.
I'm not saying that MSFT are lying. They may start a new trend of "fixed freq".
But claiming that "unfixed" frequencies is unheard of is... eh...

Eh, you should listen what Cerny said yesterday. Both CPU and GPU are at peak most of the time. 2% drops in frequency ( that's around 55 MHz ) are in worst case scenario and it's still at 10.2 TF. What, you want to difference in TF be bigger? Naaah

Cerny mentioned yesterday that only 2% of clock speed is needed. So, that's around 55 MHz.

I listened to Cerny, I will just wait for an in depth analysis by places like DF WHEN THEY GET THE ACTUAL CONSOLE to draw conclusions, Cerny’s presentation was embarrassing. Compare what he was saying in the ps4 presentation with what he said for the ps5, both presentations are available on Youtube. When he talks about how meaningless TF are and how he dislikes a big number of CU (!!!!!!!!) he legitimately gave me a smile. Silence is golden sometimes.

No, it was done in 2 weeks time, hardly any real usage of XS's features and abilities.
But that's only part of it, when they covered Gears 5 they were already impressed with what was achieved + artistic style makes it hard to distinguish.
That's the best explanation I can give you as I saw both videos (basically it looks really great on Xbox X when compared to PC but it's NOT a game build on NG specs).

you're twisting it again.
what is unheard of is advertised best case scenarios you reach but not at the same time to not look bad.
or you will tell me that 3.6ghz and 12.1ghz on xsx can't be reached an sustained at the same time(and if it's the case i misunderstood that part, it's not impossible)

You do understand that this was just a small presentation of how enhanced BC will work on the XSX and not a presentation of an actual XSX game right ?

Nah, looks like you didn't. So, DF surely know better than Cerny how PS5 is designed? LOL

I'm kinda stuck on the fence with whether the PS 5 will maintain 2.23ghz the majority of the time. Cerny said it would, and I dont take him for too much of a liar. I kinda believe him.
His explanation was that they reversed the way it's typically done.
The XSX has the speed locked, and the power draw goes up or down depending on the load on the APU. He then said the PS5 has the power draw locked, and then the frequency goes up or down depending on the load on the APU.
So from what he is saying, if the game or scene is less demanding, the frequency of the GPU and GPU will drop, thereby lowering heat thermals on the APU. If the scene is demanding it will run at the full speed.
That is why it is variable in speed.

Cerny is the man responsible for the ps5 , he is not an impartial tech person. Some of the things he said were embarrassing, had a MS tech person said some of this stuff he would have been laughed out of the Internet and rightfully so. Again compare his thesis on console design for the ps4 and for the ps5.
Well the same people’s previous semi-Gods were Kleegamefan and osirisblack and now that their God spoke they advise us to listen to him and believe everything he said in blind faith. No thanks....

Again, all Nvidia and AMD GPUs always advertised max clocks and max TF numbers.
Why they can reach it, but Sony cannot?

Not only DF. If you read video game forums from all countries, everyone seems to understand and know much more about PS5 than Cerny overnight. It is better to take it with a lot of humor.

They can reach it but not consistently, have you never used a pc graphics card in your life ? Something has to give in, in the pc space too, whether that’s GPU or CPU when it comes to maximum clock speeds or most PCs would explode.
Ask yourself if both the CPU and the GPU can sustain peak clock speeds all the time why Sony, for the first time ever, gave variable clock speeds in its spec sheet .

Cerny is an employee. Again what did you expect him to say ? The guy said that many CU is a bad thing !!! I have never in my life ever seen this thing being said by ANY tech expert.

PC cards change their clock multiple times within one frame.
What's the problem?
I did heard about game that will damage AMD cards though, but it was a long time ago. And people who made that possible: use a PC card to full 100% for an extended period of time, they don't make these people anymore.
So, it will be all right.
Yep. I do.
