Just delay the damn system until Fall 2014. Put a beefier GPU in the fucking console while you're at it.

You mean spend 500 milllion more dollars, test-test-test, manage to piss off third parties who you have TIMED exclusives with, AND give Sony a head start?
 
There is no way I am purchasing a XbOne anywhere near launch now,mI'm not risking this.

Thanks insider friends.

Im more siding to this.
Seems like a fucking mess with the higher ups at microsoft.
Maybe that is why they are restructuring and give mattrick a better place.

It seems like Microsoft made poor architectural choices this time.
The idea of making this all-in-one entertainment box with 8GB of slow memory has compromised the whole design at different levels.

You might get some of that in PS4 exclusives, but multiplatform games will be layed out for the least common denominator, and most devs will choose the XBox One for that.

Generally, we shouldn't forget we're talking about the GPU's performance here. That means an increase in resolution would come for free, however an automatic boost in framerate isn't guaranteed since the CPU's performance is rumored to be the same.

This logic baffles me, and I don't know why people think this will happen just because.

At the end of the day the console that sells the most becomes the lead platform whether it is underpowered or overpowered, there are instances like the Xbox vs PS2 where the Xbox was the lead platform and was highly favoured by PC devs because of ease of programming, but from what's been said so far Sony is farther along in that regard.

Normally the first year of a console's new launch is ass in terms of displaying what the new generation is about from third parties and you usually end up with what ultimately feels like up-ports from the previous generation.

A slight downclock isn't going to cause drastic differences like in the scenarios you detailed.

PS4 going from 192 GB/S to 176 GB/s was as trivial as this downclock.

It wasnt a downclock... They basically used different memory chips at lower frequency.
 
25% of the APU is occupied by 32MB of ESRAM.

I don't get it man. I just don't get it.

Better than having a failed product for 5 or more years. There's a real chance this shit is gonna backfire.

It not all doom and gloom for MS

power has never determined the winner and its certainly no wii/wiiu situation in regards to power and 3rd party support.

As long as the X1 gets the same 3rd party support as the PS4, the power difference will only effect like 5% of the gaming population.

I don't think going embedded memory with DDR3 was that bad a decision. What I really don't get is why they went with 6t-SRAM instead of eDRAM. The size difference is humongous. Are there production/process advantages to this I am unaware of?

Right now, the EDRAM seems to be only available on 40nm/32nm nodes. 28nm EDRAM is in development, but I'm aware of any shipping products with it.

For MS, I think the decision was a XCGPU setup APU + eDRAM daughter die, a WiiU like setup with CPU and GPU/EDRAM on separate dies (since the eDRAM would be on a different node), or APU with ESRAM on chip. In theory, with everything on chip power consumption and performance could be better.

Using eSRAM guarantees that there will be little issues when shrinking to 20nm, 14nm, and if there's anything beyond that as SRAM is fundamental to any chip design. eDRAM is not guaranteed at those nodes. I think MS just decided to bite the bullet knowing that yields could be an issue now, but after a shrink to the next node, the decision will payoff. It seems everything was designed with long-term cost savings in mind.

Too late better suck up the damages and take on the 3rd gen console curse and rise again like a shining phoenix like sony with ps4.

If there is a 3 gen console curse then the PS3 most have an ample supply of 'curse be gone'.

Two things:
1) The Xbox 360 was/is no joke.
2) Sony performed most of the 'cursing' on themselves.

Wait!.... I didn't refute anything did I? o_O

Ah so those(ME2, Titan, DR3) are timed exclusives like Bioshock? Any idea how long the exclusivity lasts? I'm guessing a year?
 
Same. He's progressively tanked Microsoft and it's stock. I know people will say the stock is on a high right now, but so is most stock, since it's false comfort and boom coming off the back of a great recession.

So if you don't believe in the stock pricing, maybe you should look at their financials instead? Then do a pro forma for the next five years? Then show everyone how MSFT is going to tank by setting your stock price target? Remember that the LTG is a large factor in stock pricing so if you want it to tank, make it negative.

And if you end up being right over all the industry analysts, you could get a job making millions too!

I don't see what the Xbone being weaker has to do with the quality of visuals on the PS4.

PC ports of all 360/PS3 games hands down destroy their console counterparts. It isn't going to be very difficult for devs to make their PS4 games prettier than the Xbone games.

Clearly.

And let's not forget, similar GPU (but faster) and CPU architecture.... with better tools and more available unified and faster ram...

Turning on graphical options will be easy as cake.
 
Best part about timed exclusives is that developers tend to put incentives to buy the game on other platforms. Now add in a vast power difference and those timed exclusives will end up being way better on PS4.

This is where I'm confused, it sounds like these "rumors" just came from a Gaf discussion in the other thread? How does anyone on Gaf have that insider knowledge?
I'd say that the development side is pretty well represented here on GAF, like almost any videogame related group; the outlier being games journalists. They come here to read, but they reply on Twitter.

EDIT: Oh, you were talking about manufacturing specifically. My mistake.

Why would being a GAF member preclude someone from having inside knowledge?

It wouldn't necessarily, but I wasn't aware anyone on Gaf worked at MS or the manufacturing locations and could share this kind of news. Just seemed from the OP like two people speculating, and further down one even mentioned the problems were not true.

This makes sense, thanks for the explanation.
 
I just wanted to thank you for your contribution to the thread with this personal attack, which seems to be standard practice for you. Just for your own reference, here is this post that you always seem to fail to look at :



You're right, everything I say must be off Beyond3D, right? Even though much or most of that content wasn't on B3D during those dates. Was I wrong about memory? Yes and no. At the time where I had garnered information on the PS4, it DID have 2GB of GDDR5 and at its original release schedule, it was going to end up with either 2GB or 4GB. 8GB is Sony getting lucky. I admit to being wrong on that front, and what I say can be corroborated.

Next time, Heavy, instead of hurling personal insults dispute the content of my posts, not the posters themselves. Or go back to WrassleGaf.

Every single quote there was speculation and educated guesses that anyone could have typed from scouring B3D or even here. Barely any specifics. You even linked a quote where you bolded where you said "it will have 8gb of ram"... in a thread about the same subject, and then used that post in your compilation. You don't have any sources. Even in this thread all you did was ape Thuway's rumor. "Yeah, my sources tell me the same"... durrr. And I'm not personally attacking you. Stop trying to spin this into a "personal attack" in an attempt to get someone in trouble. It's called questioning your already dubious credibility, which is perfectly fine to do in a medium like this.

would someone mind updating me from yesterday?

as of the OP, it sounded like the issue was not actually GPU clock speeds, but esram limited. is that still the case, or has more information come out pointing to downgrading clock speeds again?

also, in addition to hardware issues, the OS is fucked? this is based on inside information or just that the reveal demo was faked (which i'd assume would virtually always be the case for a big reveal on stage with early hardware and software to avoid bugs/crashes/embarrassing moments)

People tend to think in patterns, for example many thought that this gen, MS would launch first and Sony would slip into 2014, because that happened last time so its bound to happen again sort of deal

They think because 360 was the often the lead platform for multiplatform games that it will be that again, without counting on the fact that the 360 launched a full year ahead of the competition

The idea that Microsoft will mandate that the PS4 version cannot look or run better is down bizarre, neither MS or anyone else has that kind of leverage to ask this of publishers, its beyond insanity to suggest it. Xbox 1 games and GC games often looked and ran better than the PS2 versions, despite Sony dominating the industry at that time.


People thought that Microsoft would easily make a more powerful console than the PS4 because they were/are financially better equipped to do it, and yet here we are. Its the same reason people threw logic out the window and thought EA was going full exclusive on Xbone.

Publishers have nothing to gain to appease MS or Sony, they will try to push their games as much as they can in order to make as much money as they can. And MS is not some worldwide mob organization that can threaten people with demands, this isent the wild west.

Well at the end of the day, just how bad could it be? I admit I was never a fan of the One for their DRM policies, but I find this amazing this late in the game they only now just realized they had such a huge potential problem.

Will this make them delay their launch, or will they lower their clocks enough to make the system stable no matter how much they affect performance.

They also mentioned 768 operations per cycle, is compatible 768 opc with a frequency downgrade?

That's just a product of the number of shaders. Each shader can execute 1 multiply-add operation per cycle.

Unless they start disabling shaders, that number won't change.
 
How can Microsoft be so bad when it comes to hardware. They have so much money, why can't they hire people to be smart in this.

They did hire the best people to make the hardware. But at the same time, they gave those people a shitty goal.

In reality, it could've been worse.
 
It not all doom and gloom for MS

power has never determined the winner and its certainly no wii/wiiu situation in regards to power and 3rd party support.

As long as the X1 gets the same 3rd party support as the PS4, the power difference will only effect like 5% of the gaming population.

Outside of digital foundry and similar technical analysis, most people will never notice the real-world difference between the two consoles. Those "50%, 33%, 123.4%" numbers throw out really don't mean much outside of the paper its printed, mainly because for both boxes we do not know what the system bottleneck is (my guess is the CPU for both). And in the long run, bottlenecks is where the great equalizer is located. If the X1 has a worse bottleneck, then it will be worse, and vice versa for the PS4 if it had a more severe one by chance.

I like that answer more, I was thinking about this earlier about how MS is trying to compete with EVERYONE and make a product to capture everyone and everything in it that to try to get there, they're going to miss their goal horribly.

It was a bet, like any other bet, but the downclock isn't what is worrisome, it's the half baked OS. I hope they just fix things in time. I'm optimistic they'll get it right, but it might be a few months after launch.

They have a very ambitious goal with the Xbox One OS.

You cray. Shitty downgrade is forever. They can fix a shitty os.

I still hold the thought that in previous generations it was easy to mask power differences through showpiece games most people couldn't tell the difference between unless side by side.Except last gen when it came to the phenomenon that was the Wii, which I don't think we will see again this gen. Part of that was because of the differences in architecture making porting and optimization more of a hassle. However, this coming generation the architecture is the same with PS4 actually having all the advantages of better specs, unified memory pool, and a maturer dev environment. So all of that should make optimization for the PS4 not only easier but yield very noticeable results. Jonathan Blow even went as far as speculating it could be a difference of the PS4 getting a 60FPS version while the Xbox gets 30FPS.

The real kicker? The PS4 could very well be cheaper to purchase.

Xbox's "all in one" approach kinda reminds me about this:

Their goal relies more on (a change of) perception than (a change of) reality. They have built a filter/funnel. I don't see why they can't succeed.

CPU is only a bottleneck if a game is designed to demand a lot from the CPU. This is highly up to a game per game basis.

Even so, considering the fact that GPGPU is going to be a big thing this gen, even more importance will be put on the GPU as it will be able to pick up some tasks normally given to the CPU (physics being the obvious one). I actually don't really think the CPU will be much of an issue at all this gen if the physics are offloaded.

Better than having a failed product for 5 or more years. There's a real chance this shit is gonna backfire.

Even if Xbone will release at state like rumors say it won't be failure. Only failure will be when Xbone won't sell.

Someone here said eDram can't be produced everywhere (only few fabs)

For everyone asking- this information is all pretty recent. Around the PlayStation Meeting the Xbox One was way behind (OS + hardware). Engineers were scrambling to get things sorted out.

It turns out, they didn't sort it out. The OS you saw was a complete and total lie. The current plan is to get the yields up, lower the clock rate, and to have enough units out for a sell out in the Fall.

Honestly this sounds to me more like they didn't plan at all lunching 2013 but Sony suprized them and shit got real @ MS. This would explain why they waited so long for response to that meeting.

One thing is sure. Sony got lucky a lot.

I actually don't really think the CPU will be much of an issue at all this gen if the physics are offloaded.

Honestly after you take physic off from CPUs there isn't really much that CPU need to calculate. Only few games on PC are CPU limited like Civilization and i don't see many of those games being on consoles.

For those asking how this affects performance- to be perfectly frank; it is nothing turning down features won't solve. The mass market will never notice a difference between 1080p and 900p; neither will they care about dynamic shadows / global illumination / or tesselation. Go to your PC - and turn shadows from Ultra to medium, disable tesselation, and lower the resolution to 900p; and you'll find games run totally fine.

Microsoft is purely behind and it's now time to make drastic decisions. I don't think any one is happy about the lower clocks, but no one is depressed about it either. The Xbox One is an all-in-on device; and that's how it will be marketed.

Good grief, what a disaster. No wonder they're rumored to be launching a salvo of money hats to third-parties for exclusives.
