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.

So XB1 has 2.5 OS now?

I don't think that's going to happen if the difference gets so massive. If you're going 1080p on PS4, you would have to drop to 720p on Xbone to get comparable performance. If you're going to something in between on the PS4, you would have to cut more on Xbone unless you're going sub-HD. Either way, PS4 will end up with a massive IQ advantage. If the devs target a solid IQ on the Xbone and design their games around that, they games will end up looking poorly compared to PS4 exclusives. If they want to match Sony's 1st party stuff, they'll be forced to make severe IQ concessions.

Good points, well made. However this shakes out I think the possible disparity involved could put 3rd parties in a genuinely tricky situation when direct comparisons are drawn to devs fully pushing the more powerful machine. Much like when PC is lead. It might even mean increased second party and/or one off exclusives trickles here and there. Or maybe just a renaissance of art style over realism (where the differences wouldn't be anywhere near as noticeable). It's certainly going to be interesting to see how it all unfolds.

In theory if this is the case, down the line with a slim version when they get the yields fixed they can fix the clocks correct?

Yeah, a fractured skull is hilarious...

Seriously, you could kill somebody doing that.

she landed on her back, a few bruises and tears and nothing more.

It Was stupid from the guy though, he must be really sensitive to get a drink splashed on him lol
 
I thought those Data Move Engines were just PR nonsense for DMA... which the PS4 will definitely have.

Or is it something more than that?
The DME are another part of the silicon commonly accepted as true. Digital Foundry, for example, assumes that it's there although aren't part that big complex SoC with yields problems. They are there to fix the low bandwidth of the system and if this rumour is true they are more needed than ever. The less powerful the X1 gets the more it needs to be more efficient than the PS4.

Worst comes to the worst they'll delay it...honestly £99/$99 360 with one or two exclusives this xmas will be enough for MS.

That then gives them time to delay the X1 until just before the MS new financial and at least helps them gets some time to fire Marc Whitten and takes some control and rethinks the device.

You can't have some consoles play a game better than others.

The platform is whatever it is day one.

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?

Different fab process (or foundry) is what I vaguely remember reading once.

No. You can't do that mid generation, anyone who has the old hardware wouldn't be able to use the new games/features that you just enabled in your hardware revision.
 
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.

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.


Yeah unlike some of the info we had that was quite old all this stuff has been coming out only recently and only get reconfirmed over and over.

People should have seen this coming though when MS didn't announce anything about the GPU and instead focused on the transistors which was ridiculous. They are using misdirection and dropping random spec info in a attempt to make casuals think "Wow 5 Million Transistys is a lot!!" They very likely won't be revealing the specifics of the GPU even at E3 and take a page out of Nintendo and keep that stuff under wraps.
 
No, it is in theory easier to manufacture than EDRAM in smaller nodes due to not having capacitors and above all, due to not depending on others to do it ( IBM, NEC...).

Is it impossible to design it with redundancy so you can disable part with defunct transistor ?

Truth. This post has it.

There would be no point because devs would still be bound by the original specs.

Hardware parity is a must for game consoles. Otherwise there would be weaker consoles in the wild that would not run games.

I don't doubt that they're there, just that they're not really a distinguishing feature because DMA is a standard part of any modern architecture.

They may have an LZ77 codec and a jpeg decoder, but I don't know that that is going to make a huge difference.

I dunno. They're there for a reason, of course, and they'll make something of an impact... but they're not going to help a drop from 1.2 to 0.9/0.8 TFLOPS. You can move data around as fast as you like, but it's not going to change the throughput of your GPU.

I'm just skeptical, the whole Data Move Engine thing reeks of PR BS.
 
Thank you!!

My home is a breast with MS products, however folks should remember why MS got into the gaming business to begin with. Hint.. it wasn't to make money in the gaming industry.


What we are seeing today with MS is their end game/goal. MS is betting that they are the one software company that can bring all the components of life and entertainment together. And by doing so will become the only information gathering conglomerate that will have a major television viewing angle.

Guys "Please understand" Nothing makes money like advertisement sales and MS is looking for a piece of That pie. Not gaming.


You know, an always-online, always-on Kinect would be pretty useful in gathering information about your TV/advert viewing habits, interests....

MS still make a lot of money under Ballmer even if it's obvious that it's total short-termism. He's no Howard Stringer.

MS would even make a lot of money under me playboy, and I know dick shit about business. Aside from common sense.

Unfortunately it's not. There are performance issues. In some cases, its quite significant.

Bkillian was right, the new Xbox team turned the product into the next Kin.

I was reading the gametrailers/youtube comments on the reveal video, and many were 'yep same specs as PS4, 8 core CPU, 8GB RAM'

Pretty ridiculous

It is BS.

Its a renamed DMA controller with some FF compression hardware.

Oh, I didn't know that. Thanks for the info :)

Another confirmation. I'm fascinated to see how this turns out.

The bird has spoken.

No, they do it all the time for DRAM, and I'd assume they could do it for eSRAM too. It's called Error-Correcting Code memory, but it comes at a cost of a LOT more transistors, and the cost of...well, a lot more cost. If you're building a cruise missile or a supercomputer, it makes sense. For a console, not so much.

EDIT: and if the problem really is a timing issue, adding more transistors would only exacerbate the problem.

Seriously, you could kill somebody doing that.

If you do stupid things, other bad things will happen to you. Stupidity is one of the leading causes of death nowadays.

Seriously, that could have been bleach, or acid in that cup. Never know.
 
Either way, weather or not its downclocked, 1St party games will still make Xbone great, right? Didnt the Wii survive pretty well last gen...

If heat is a factor in the problem, I suggest they call Nancy Tellum to Engineering quick, she'll hook them up with a watercooler for the watercooler
 
In theory if this is the case, down the line with a slim version when they get the yields fixed they can fix the clocks correct?

They could but the older models would be the lowest common denominator from a development standard still.

MSFT won't ship with a downclocked chip that will be upgraded later. Makes zero business sense.

If there are yield issues, they will bin the chips and (console) supply will be low until yields are fixed. That is the ONLY thing that will happen if any of this is true.

EDIT: I'm not buying these insider rumors from anybody at this time as they are too outlandish. At best, there is some small tidbits of facts, like yield issues in the first steppings, that are being extrapolated and / or opinionated into what is going on.

I don't understand how someone who is clearly mentally challenged is allowed to run a company the size of MS.

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.

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

Imagine for a moment if Sony wouldn´t have gone finally with 8GB of RAM. The MS marketing campaign with the 8 in capitals everywhere...
 
Just delay the damn system until Fall 2014. Put a beefier GPU in the fucking console while you're at it.

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.
With all the virtualisation i wouldn't be surprised if they came out with a new box within 3 years.
