3-3.5 years of development is 'too soon'? The first one took 5 years because they had to reboot the entire series and ran into creative issues.

I'm pretty confident I've heard Barlog say, 'The next ones wont take as long' or something along that nature. The game was in a terrible spot as well. If anyone has not watched, Raising Kratos, I HIGHLY RECOMMEND IT.



This. Also I would expect it's way easier in dev and more gain time now for SSM to implement no camera cut in Ragnarok with SSD compare to what they used to with ps4 hdd.

Yeah, well, I can record a waveform like that with ambience noise, that doesn't say much of anything, and is not like Audacity is a particularly brilliant software for audio. And anyway, you said it yourself:

"If I listen to that recording I can hear ambience in the quiet parts but nothing that I could identify reliably as the One X operating."

I explained, in my previous post, the reason as to why a sound, being there, could be harder to identify. And you're saying yourself how in the "quiet parts" the mic is picking up the ambience sound. The console working is part of that sound. And this most likely without a good mic for these kind of measurements (even within the 300$ range). Again, you may think that I'm disputing the fact that the console is quiet or anything like that, and I'm absolutely not. I'm just saying that, because of how sound works at a physical level, what Jez said is inaccurate. Is all I'm saying, I'm not denying his claim that the Series X is a quiet console.

But I guess we'll just agree to disagree and move on, this is surely tiring for both of us.
Well, we actually largely agree. With the console running in the same room his level meter wasn't registering anything - that's his experience in his setup. You said that you could do the same thing yourself, just as I replicated that result with both Adobe Audition and Audacity. It's really not an unreasonable thing to claim.

I'm also not disputing that the console makes sound or suggesting that it couldn't be recorded with the correct equipment, it's just a seperate issue from the tweet that triggered some people (well, one person :)) to unfairly brand him a 'liar'.

So why did MS choose to not implement it, since it’s an AMD feature that is available to them? They worked closely with amd on these new chipsets, so if it only offers advantages and would mean an even more powerful console then why do you think they didn’t choose to use it?

Parity with PC? Because the chip will be used for the cloud? MS and Sony have completely different goals next gen, therefore they have completely different implementations.

I agree with your overall view that the XsX design decisions were guided by the server side, but I really don't think they had access to the continuous boosting technology in the PS5 APU.

The reason I think that, is IIRC power draw (of air-con/servers) is the biggest issue with a server farm, so even if it cost die-space and meant they needed more space for more servers, the continuous boost clocking technology at the lower clock would have yield lower cost per performance than what they have in the XsX. And they'd still have the ability to do it as fixed clock - as their fallback - if it wasn't working out for reliability, etc.

Even a server partially utilised (less than 4 copies)would have given them great gains using the PS5 boost tech IMHO, and would have worked better(less power draw, less heat) running different demanding games, say if running a BC game in the cloud.

Its debateable whether Microsoft were involved in gated frequencies or not, at the end of the day the application is clear anyway.

The fast frequencies is more than just adding controls to the CUs, the 10 CU per shader array and layout cache, shaders and other parts will be optimised to lower the distance travelled on silicon for signals to achieve these high frequencies. Its alluded to in the RDNA1 white paper, and it was mentioned in the RDNA2 CU slide but using general wording.

I wish we had a ps5 die shot, but if you look at 6800 die its clear how everything is arranged for this purpose (close and fast). XSX is the opposite of this arrangement from hotchips.

So for XSX, you would also have to reduce the CU 10 to per shader array and re-arrange everything and would need 5 shader arrays and a 60 CU die with front and back end scaled to match 5 arrays (which does not work obviously, and 3 shader engines would be 6 arrays so even bigger and still not fit the bill).

And as I said with 4 instances or games running, 5 or 6 shader arrays does not fit the bill.

So sony likley wanted 36 CU and go fast, Microsoft wanted a sever class CPU and 4 shader arrarys with no freqjency gating and TF. Hence 2 totally different directions, chalk and cheese.

I think he wants to see if it will drop during gameplay.
Ok? That doesn't address what I said. People want to know how often the GPU or CPU won't be having their full power, meaning that 10.2TF isn't all available.
I think some of you may have a heart attack if you see the fixed XBOX clocks don't exactly stay fixed...........

But people are saying it only offers benefits, like reduced heat and power draw, which would benefit the cloud server setup immensely. Again, if there is no drawback why wouldn’t they use it?

Don’t need it at all. The SSD they are using is already fast enough and DirectStorage is coming to PC too so it will be very easy for devs to optimize for Xbox and PC.



Why don't they have a better sound engine like sony's

The sound engine on Xox Series is also very good just look at Project Acoustics:




Why don't they have the latest version of wifi usb-c



It’s a gaming console. Why would you need the latest Wifi or USB-C? It doesn’t provide a meaningful advantage.



Why don't they have any exclusive launch games?



MS has a huge ecosystem, they don’t care if you play their games only on XSX or only on PC. All games will be on XSX and PC. Consoles are now like PCs more than ever, it’s very easy for Devs to create games for PC and XSX.



why did they not invest in have a better controller like sony?

I like the Xbox Controller more due to ultra low latency and better analogue stick positions.

And all those features the DS has, what if devs forget about those features in a year or two, like they did with the Switch HD Rumble or the DS4 Touchpad? Not many devs use those features, except at launch.

Also, due to corona not many people have that much money to pay $70 for another controller to play with their friends together.

But again, if AMD show them this feature that literally has no drawbacks and makes the APU better, why wouldn’t they do it? It doesn’t make sense.
Because the wanted to play it safe, they didn't find a reason to change it since nearly every console in history has followed this convection so they did the same or maybe they couldn't implement it as good as they wanted to so they didn't bother.

They both have draw backs and upsides there's for and against each solutions each company did what they thought was best, if that wasn't the case you can just ask why didn't Sony do the same as Microsoft and nearly all consoles prior if fixed frequency method was so superior?

no, they could easily implement it. But they won’t. Why should they? They already have the most powerful console. And they want to make it as easy for the developer as possible.
And having sustained and predicable clocks makes it easier for devs than variable clocks.
No, ps5 doesn't take much more trouble than Series x, the clock adjustment happens automatically, also dev can use fixed frequency profile while developing games, ps5 will adjust clocks automatically for consumers.

Your honesty going to sit there and tell me your happy with a 12 tflop machine when a 10.3 tflop one is trading blows with it in parity.

Microsoft unfortunately went with the standard option, sony are the ones that are innovating. look at all those examples i gave, there is no question there. Why would you not want the latest tech in your system, what happens in three years time when something comes around that needs it, silly, very silly.

Without question Sony's machine is better engineered, a 10.3 tflop machine, trading blows with a 12 tflop one, while having all those extra goodies i mentioned.


Microsoft have a huge ecosystem lol, with no launch titles haha, done like a kipper.

But if you want to believe Microsoft's spin, luckily the vast majority of people are heading towards sony's system, yer it must be them that's wrong, not you. Have a great day. :messenger_heart:

It could be that because Nvidia doesn't offer something similar (enough) so they can't implement it generically in DirectX 12 and don't want the headache of maintaining two power management paradigms. This is the downside of having an API that has to account for multiple types of target hardware. The benefits are that as it is more abstracted they can do things at the API level that will apply to all (hence easier BC enhancements)

Also I don't think Sony took Smartshift off the shelf, I believe the fundamental technology used in AMD based laptop GPUs was taken and customised specifically for console to allow for a fixed power budget. This kind of thing is the benefit of having a single target hardware profile.

Oh so AMDs smartshift isn’t actually anything new then? The Xbox has the same power shift as the ps5 then?

Smartshift is just marketing and shifting power around on die, which is what Big Navi does (and Ps5)

Again, why would mcirosoft want to push power from CPU (when its doing little work at end of a frame) to GPU if there are 4 games running.

When you design for 4 games at once, the design requirements are totally different.

I mean not long to see how all this plays out. Ps5 gonna have some serious good looking first party stuff anyway. I just don't buy the spin that lowering clocks but not detailing the amount is somehow revolutionary and in our best interest. If ps5 outstrips the performance of series x in 3rd party releases then I'll be amazed and will eat my crow, and i hope those saying opposite will do same. I just can't see it from the numbers

Do you have proof of this? I highly doubt the series x will not adjust clocks at any time. What about just sitting on the home screen or watching Netflix? Is this gonna be 12 TF? Digital foundry have already measured different power draw for different games, indicating different clocks for cpu and gpu.
As expected, we're getting eight CPU cores and 16 threads, delivered via two quad-core units on the silicon, with one CPU core (or two threads) reserved for running the underlying operating system and the front-end 'shell'. Microsoft is promising a 4x improvement in both single-core and overall throughput over Xbox One X - and CPU speeds are impressive, with a peak 3.8GHz frequency. This is when SMT - or hyper-threading - is disabled. Curiously, developers can choose to run with eight physical cores at the higher clock, or all cores and threads can be enabled with a lower 3.6GHz frequency. Those frequencies are completely locked and won't adjust according to load or thermal conditions - a point Microsoft emphasised several times during our visit.
But up until now at least, the focus has been on the GPU, where Microsoft has delivered 12 teraflops of compute performance via 3328 shaders allocated to 52 compute units (from 56 in total on silicon, four disabled to increase production yield) running at a sustained, locked 1825MHz. Once again, Microsoft stresses the point that frequencies are consistent on all machines, in all environments. There are no boost clocks with Xbox Series X.

Remember Ps5 is also a 17 % or so smaller die, so if the performance is within 17 % or closer to parity, then the design choices were correct.

If the performance of XSX > 17 % differential, then the design choices were not so great IMO. lets see.

TSMC 7nm is very expensive and the major cost component.

Great points about the software convenience the current GPU setup gives them for running 4 virtual machines -with less software complexity.

That does remind me that Bo_Hazem Bo_Hazem and me were discussing(many months ago in this thread) the AMD Eypc roadmap, Infinity fabric, the incoming Eypc solutions, likelihood of chip stacking that had helped AMD win a first US government server/cloud contract that will be happening next year, and what that might tell us about the PS5 APU.

If the US government solution is almost certainly using gated frequencies with RDNA2-3-ish technology for a similar purpose to Microsoft's servers, and Sony will again most likely try using Playstations for their Sony Pictures CGI cloud with PS5 - that has gated frequencies or even more advanced. Other than the difficulty of virtual machine complexity, which for Microsoft being a business software company shouldn't put them off, it is hard to see (IMHO) why they wouldn't have copied the US government choice in tech, had they had it available.

You are completely right, though, a die-shot of the PS5 apu will certainly tell us far more.

Each L1 private to each game makes sense to me, but I dont design game servers so I am just speculating, but I cant see how could time slice game application L1 caches like that anyway for cache misses etc.

I am sure there will be other differences, the display outputs and other stuff will need 4 x , its more complex than we are talking here. I am sure ps5 would be awful at running 4 x ps4 games, its not desigjned to do that.

Phone reception is more important to me than human rights
1.-If you are dev with access to a dev kit you already know it because you need that kind of info
2.-In PS5 the clocks can drop depending of the kind workload you system is doing in that moment
because clock != power consume is more (clock*workload)=power consume
3.-The games are not stress test as many people think
4.-The locked clocks are are the norm in current/old consoles like PS4 and Xbox one X but are not invencible
5.-If you have a scene which stress too much your system with locked clocks, can shutdown it, see the issue
which happens with Watch Dogs Legion in Xbox one X

6.-Any decent game dev will not use Flops as a magical measure, only the marketing and fans/users use that metric
in so universal way

The conclusion could be: is okay to have curiosity but if you are not someone who really need that low info is because
you don't need it, as user you should only care results not more.

Cerny even mention such a scenario in the DF interview:


But what if developers aren't going to optimise specifically to PlayStation 5's power ceiling? I wondered whether there were 'worst case scenario' frequencies that developers could work around - an equivalent to the base clocks PC components have. "Developers don't need to optimise in any way; if necessary, the frequency will adjust to whatever actions the CPU and GPU are performing," Mark Cerny counters. "I think you're asking what happens if there is a piece of code intentionally written so that every transistor (or the maximum number of transistors possible) in the CPU and GPU flip on every cycle. That's a pretty abstract question, games aren't anywhere near that amount of power consumption. In fact, if such a piece of code were to run on existing consoles, the power consumption would be well out of the intended operating range and it's even possible that the console would go into thermal shutdown. PS5 would handle such an unrealistic piece of code more gracefully."

Ppl with so many questions, "concerns".....just read the interviews, watch the video of said interview.....and please actually watch The Road to PS5.

It depends on priorities when allocating costs, Microsoft spent the money on things that actually matter to games, more compute units, faster CPU and higher memory bandwidth with a bigger SSD.

Ever heard of exaggeration?

But just applying a similar difference between your comparison. What was the purpose of your exaggeration? To say that having a faster ssd is useful, think everyone wants a faster ssd but that's not really that interesting unless it unlocks a step change in game performance/development that the xbox can't achieve. The real change is more likely to be from moving from 7200rpm drives to a nvme ssd.

Microsoft designed a server class CPU to optimise running 4 games at once at 1080p. They said so at Hotchips.

The GPU was also designed with this purpose (4 shader arrays), and indedd the memory bandwidth to facilitate 20 or 40 GB GDDR6 for servers.

It is clever how MS did a dual purpose APU for sure, but MS requirements were totally different to PC gaming and ps5 parts.

SmartShift shifts power to the CPU or GPU or both on demand. That is done through Infinity Fabric, Memory Access and Machine Learning.......If the XBOX can do that, please specify it in the MS Docs and PDF.....

I think most of us will be waiting for your breakdown on the matter, since you are so sure of yourself, I'm thinking such information should be at your fingertips.....Can't wait for your breakdown on the matter since you are so genuinely passionate on the subject...
 
3-3.5 years of development is 'too soon'? The first one took 5 years because they had to reboot the entire series and ran into creative issues.

I'm pretty confident I've heard Barlog say, 'The next ones wont take as long' or something along that nature. The game was in a terrible spot as well. If anyone has not watched, Raising Kratos, I HIGHLY RECOMMEND IT.



Yes, this. The first game as it was being developed so was the tech behind it. Now the core foundation is set and i am sure they had already mapped the flow of the story across at least two more iterations. The sequel releasing in 2021 isn't improbable at all. Could be a 2021 Q2-Q3 release!
