Xbox One has a 40nm APU? [UPDATE: Probably not]

[monstercameron]

tsmc 40nm? If confirmed, wouldn't that mean its vliw4 based...also aside, why couldn't vliw4 support dx11.1?

Am I the only one that thinks that MS did an incredible presentation?

It could have been better, yes.

But compared to the Wii U and PS4, I'm actually looking forward to E3 and see what else the Xbox One brings to the table.

MS has a winner here. IMHO

Compared to a black blurry box shot from 100 feet away and numerous views of a PS controller. Hell Yeah, MS is doing a better job. You can already picture what you are going to be able to buy, with a new Forza in the screens.

that presentation did nothing for me as someone who casually plays a few games, where were the games?

the dvr/tv functions seem unnecessary(i get a cable box form whoever, how would I integrate this?).

kinect, cool, but I'm not into playing dancing games...
controller revision, ok...

it was a meh fest imho...

 

[zebrax2]

it seems ars mentions 40nm...http://arstechnica.com/gaming/2013/...u-ray-drive-8gb-of-ram-and-lots-of-buzzwords/

They used the wired as the source for that info. I also doubt its 40nm

So long as capability is similar, I could easily see myself getting xbox one over the PS4. The simple fact of the matter is that with the 360 vs PS3, the PS3 was a significantly worse experience (IMO) due to the extended update downtimes on the PS3 and the laughably bad PS online (bad in comparison to XBLG). Now that may well change with the PS4 - and I hope it does, but *as long as* capabilities and costs are the same i'm kinda leaning towards Xbox one. I gotta admit , I thought the media capabilities, integration and motion gestures were kinda cool - PS4 had *nothing* similar to that in terms of ease of use. OTOH, I was greatly disappointed that the games shown were incredibly lame. The new remedy game trailer didn't even make sense, Sony did WAY BETTER in terms of showing off the gaming capabilities. MS definitely failed in that respect, although I do think the xbox one and PS4 will be very close in capability. Again, this all may change with the release and I may have to revise my opinion nearing launch. We'll see! I know i'm buying one console this holiday season.

Oh yeah. Regarding the topic, it has to be incorrect. There's no way it's going to be 40nm, has to be an error.

 

[notty22]

Many console launches have surprised me with using cpu's on older nodes. The final clock speeds and thus TDP are a product of whatever node they considered, engineered for. So it's obviously a interesting tidbit.

 

[NTMBK]

To be fair the Wii U is on a 45nm CPU and 40nm GPU, so its not entirely out of the question.

 

[RU482]

what is the power consumption of the xBox one or the PS4?

Could either of these be made to mine bitcoins?

Lots of leaked material says it's GCN. I don't see why we should consider one random uncited claim as it being at 40nm as more credible, much less implying VLIW4. And what would that make the CPU, Bobcat? Which we have no information of being able to run beyond dual core?

The whole idea of getting AMD to retrofit an old design for some potentially minor API changes makes little sense. The only way I could see this being 40nm with old 40nm uarchs is if somehow Microsoft froze the design a LONG time ago. Doubt they'd be this uncompetitive and waste this much money, even if Nintendo likes to do it. Only they'd be worse than Nintendo since they'd be launching like a year later.

 

[NTMBK]

Actually, this thing is seriously covered in vents.

A lot more cooling than I would expect for 8 Jaguar cores and a HD7770... so maybe 40nm could be true?

 

[Vesku]

I'm sure they don't want to continue the RROD tradition of heat death Xboxes. The cooler looks like it could handle ~150W or less.

Engadget reports it is 28nm: http://www.engadget.com/2013/05/21/xbox-one-hardware-and-specs/

Big vents looks like using bigger fans over louder fans (see first gen 360s for very loud), doesn't necessarily mean power output is larger than expected.

You are indeed correct the Xbox One has a huge fan and also an equally beefy heatsink. Should be whisper quiet.

Interesting looking packaging on the chip. Anyone know what the purpose of the metal bit around the die is? To make the heatsink sit better, perhaps?

 

[Enigmoid]

I think its that the cpu and gpu are on 28 nm (same as GCN and jaguar) but the edram is on 40 nm (IBM's edram edit:eSram is 40 nm). Several dies (cause the yields of a perfect 5 billion transistor chip would be horrendously low) integrated onto one package.

Where did you hear eDRAM? Rumors have always been eSRAM which can be made trivially on any process and integrated into the SoC.

Sorry typo

 

[Exophase]

But if it's eSRAM there's no reason at all to use IBM's 40nm process, it's trivial to make it anywhere. I also don't think it even really qualifies as eSRAM if it's not integrated into a die with something else.

I think this is just to protect the die... so you can't damage when installing the heatsink...

Cape Verde is 1.5 billion transistors. The 8 cpu cores are probably no more than 500 million. So where is the other 3 billion? The Xbox 360's 10MB embedded RAM only used 100 million transistors, so I would only estimate 300 million transistors spent on this one. Does eSRAM really use that many transistors vs eDRAM?

2.8B Pitcairn
1.2B 8 Core bulldozer.

1B everything else.

Yes it really uses a lot of transistors. 32MB of eSRAM would use a minimum of (32 * 1024 * 1024 * 8 * 6) = 1.61b transistors.

Anand's writeup also states 28nm...
