Can Jaguar be clocked higher than Bobcat?, i.e. something ilke 2.2GHz.
Semiaccurate article on Jaguar had this quote
Officially, I don't think anything has been said what clocks a Jaguar core is capable of.
10% faster at the same tdp im sure, it would be interesting to see jaguar and steamroller at the same power envelope, kinda like the p3 vs netburst years back.
bobcat ranged from 800mhz @ 5watts to 1600@18 watts. i doubt you can extrapolate power draw based on those numbers, but 2.2ghz seems easily achievable.

I've searched forum a while ago about Bobcat overclocking potential and what I found (may be wrong) is that it was pretty much a dog.
Jaguar are meant to clock higher, but I would not go that much higher 2GHz as the upper limit.
110% of 1.6GHz is 1.8GHz. Pushing voltage higher (though not free) you may reach 2GHz.

If the clock is ~ 2ghz that's not bad at all .
I think the bobcat cores can work at much higher clock, the trouble of overclocking is that you hit other limitations of the platform, since the multiplier is locked...

ARM security is basically hardware DRM.
Assuming both chips are based on the same card series, I'd read the 'supercomputer' quote as referring to the architecture rather than performance... which is intriguing.
That's true,but I'm not sure that's the route MS will take. Power dissipation scales with frequency and voltage squared. Scaling both down is almost a cubed relationship. Lower frequency requirements will also lower the transistor sizes so static power will be lower.
If MS will truly go with an 8-core CPU, my guess it will be clocked and "voltage" appropriately to fit within a power budget.
A Bulldozer based AMD Opeteron 4256EE CPU is a 8-core CPU clocked at 1.6 GHz with 1MB of L2 (per core) and 8MB of L3 cache @ 32nm it's wattage is rated at 35W.
I speculate that at 28nm, 1.6GHz 8-core Jaguar based CPU could probably come in under 25 Watts.
The question I have is that the cores have been designed in such a way that 4 share a 2MB L2. If 8 cores were placed on a CPU, would it make more sense to have them all share a 4-8 MB L2 or go with another hierarchy level: 2MB L2 per 4 cores and 4-8 MB of L3 shared between them? Or something outrageous like 32-64MB of L3 shared by both CPU cores and GPU?
Whenever I think of supercomputer I always think of distributed computing. I always thought that MS was going to go with a Power A2 derivative for the next xbox. It seems like the supercomputer model on a chip. Perhaps AMD is delivering something similar.
Actually, as dual core it ranges from 1.0 GHz@4.5W (Z-60, Hondo) to 1.7GHz@18W (E2-1800, Brazos2.0). The lowest single core is an embedded version (T16R) with just 615MHz and a TDP of 2.3 Watts.
What would make a Jaguar based 8 core version within a power budget of ~35W or less faster than a BD based version assuming a similar IPC (which is conceivable outside of FMA use cases).
The next level of HSA? A large "L3 cache" (eDRAM), which can be used by both, the GPU and the CPU? I've put the "L3 cache" in quotes as one would probably want to be able to directly address the eDRAM array.

Not sure if this was posted before or if there's any new info:

This seems to explain why Dae insisted his devkit had Intel/Nvidia parts:

Interesting...But, no doubt the dev kit picture that leaked had AMD card. Maybe different kits, although I doubt that. He does get 8-core and 8 gigs right though, and Intel CPU on custom motherboard sounds like something from Supermicro (thats chassis Durango dev kits are).
Anyway, Superdae tweeted 12 hours ago that he will post something very interesting regarding Durango in 12 hours. So...we will find out what it is pretty soon.

So I wrote this big long tweet about Durango the predecessors, and ended up losing it when I copy-pasted it, didn't end up copying

@superDaE nooooo, re-write ?

@ChrisArmota I'll do something special in 12 hours time. For now. I sleep.
The link that you gave has mostly made up information. We already know that the early alpha kits are 2 quad core Xeons and a 6870/6950.
Why not Xbox Infinity? The infinity sign is two circles side by side so it looks like 720 and it looks like an 8 on its side.

Yes, I know that.
But maybe this is why he originally thought that it was an Nvidia/Intel combo inside (he didn't realise that based on the card exterior it was an AMD 6870/6950 like we did).
Maybe someone told him (based off earlier devkits) that they had Nvidia/Intel cards but the devkit he actually got (and tried to sell) was a later one with an AMD CPU/GPU.
That's also possible, as a play on the '8'. (I could see ads where at the end the infinity symbol rotates to become an 8.)
Xbox 8 and Xbox Next were always strongly rumoured to be names for the next console (MS even secured an Xbox 8 domain)
The only other name mentioned was Xbox Loop (aside from 720, which was never going to happen, despite MS paying fan service to the name in the leaked strategy doc).
Getting rid of the identifying suffix and just going with 'Xbox' is also an interesting idea.
It's like Apple has done with the new iPad (though it makes more sense for a product that's refreshed every 6 months rather than the long lifecycles of consoles).

That Sandy Bridge processors were part of some previous dev kit also explain this:

Xbox Infinity sounds good. It even has the right number of syllables...
X-box = 2
X-box 3-60 = 4
X-box In-fin-i-ty = 6
so that means it must be right. LOL
Or it could be called Xbox Forever to disrupt Sony's next system like Microsoft did with 360.
Personally I always they would just name it Xbox Live. There's no need to have 2 separate brand names for the console & the online system. It needs to merge into one. Makes more sense now that Xbox Music & Xbox Video is now part of more than just the console & is Microsoft's entertainment brand.
